    Notes: Abstract The problem of T classification of proximal gastric carcinomas is becoming increasingly important due to a rise in the incidence of these tumors. The aim of this study was to examine the gastric insertion of the lesser and greater omenta and its role in the T classification of gastric carcinomas. The stomach and greater and lesser omenta were removed from 76 fixed cadavers and 12 measurements each were done in defined localizations. The lesser omentum extended to the gastric wall in 98% of the cases. This junction as well as the omental thickness and thus the retroperitoneal part are especially pronounced in the cardiac region. According to the current UICC classification, even advanced tumors extending into the gastric wall can be classified T2 as long as they do not penetrate the visceral peritoneum. This results in « understaging » and a seemingly poorer prognosis for cardiac carcinomas. Our study results support the recommendation of Hermanek and Wittekind [5] to subdivide the T2 stage of gastric carcinomas on the basis of infiltration depth.

    Notes: Abstract Spinal cord sarcoidosis is a rare disorder whose natural history and therapeutic outcome are not fully known. We examined four patients with spinal cord sarcoidosis both clinically and radiologically, particularly in relation to corticosteroid treatment. The initial manifestation was cervical myelopathy in three and uveitis in one. All four patients progressed slowly until corticosteroid therapy was initiated. The cervial spine was involved in all patients. Magnetic resonance imaging (MRI) showed spinal cord swelling with T2-weighted high intensity and linear leptomeningeal and patchy or diffuse intramedullary enhancement with gadolinium diethylene triaminepentaacetic acid. With corticosteroid therapy, dramatic improvement was seen on MRI, including disappearance or marked reduction of swelling and enhancement. Plasma levels of angiotensin-converting enzyme (ACE) were also markedly improved. In contrast, the clinical symptoms were little improved in one patient, unchanged in two, and rather worsened in one patient. Recurrence was seen on MRI at the maintenance dose in all four patients, without any dramatic change in clinical manifestation. MRI findings and plasma ACE are well correlated with active leasion of the spinal cord sarcoidosis, providing a useful marker for recurrence, but do not parallel the clinical manifestations.

    Notes: Abstract A systematic evaluation of anterior horn cell, motor and sensory pathways is possible by electromyography (EMG), motor (MEPs) and somatosensory (SEPs) evoked potentials, respectively, which may provide valuable information on acute transverse myelitis (ATM). In a prospective hospital-based study, EMG, MEP and SEP studies were carried out on admission and after 3 months in 39 patients with ATM. All the patients also underwent detailed clinical evaluation, and spinal magnetic resonance imaging (MRI) was performed in 28. Outcome was defined at the end of 3 months as poor, partial or complete recovery on the basis of functional status. Spinal MRI revealed hyperintense signal changes in T2 extending for two segments to the entire spinal cord. Central motor conduction time to tibialis anterior (CMCT-TA) was more frequently abnormal (90%), followed by tibial SEP (77%). CMCT to abductor digiti minimi (ADM) was abnormal in 30% and median SEP in 15% of patients. Evidence of denervation on EMG was present in 51% of patients. The CMCT-TA improved in 48% patients and tibial SEP in 32%. Median SEP improved in all patients, and CMCT-ADM remained prolonged in two. At 3 months 2 patients had died, and 18 had poor, 10 partial and 9 complete recovery. CMCT was correlated with miscle power, tone, reflec and MRI changes. Patients' outcome of was correlated with CMCT, SEP and EMG. These results are consistent with pronounced involvement of dorsal region of spinal cord in ATM. MEP is more frequently abnormal than SEP.

    Notes: Abstract  Objective: To contribute toward the understanding of the therapeutic management of fallopian tube cancer. Methods: Recent studies related to the treatment of fallopian tube cancer were reviewed. Results: Current evidence indicates that even patients in early stages have nodal disease, and often experience relapses in distant sites. In advanced stages, survival prolongation by the use of platinum-based chemotherapy has been demonstrated. Aggressive cytoreductive surgery followed by chemotherapy and negative second-look laparotomy offer the possibility of long-term survival. However, a significant fraction of patients eventually relapses after negative second-look laparotomy, and a poor survival rate after positive second-look laparotomy has been observed. Conclusions: This series suggests the need for thorough evaluation of lymph nodes at the time of surgery. The use of platinum-based chemotherapy is probably the best adjuvant therapy for both early stages and advanced stages. The clinical value of second-look laparotomy will remain limited until effective salvage therapy is developed. The potential benefits of neoadjuvant chemotherapy and the use of paclitaxel will be increasingly important.

    Notes: Abstract Five patients suffering from spinal epidural abscess associated with neurologic deficit are reported. Four patients underwent a decompressive procedure for abscess drainage, and one patient was medically treated. One of the patients showed a neurologic deterioration at the early postoperative period. The long-term follow-up showed a good outcome in all patients. It is concluded that epidural abscess associated with progressive neurologic deficit requires immediate decompression and administration of antibiotic. Postoperative neurological deterioration may be seen despite proper and immediate decompression and in such a case neurologic improvement is observed in the late postoperative period.

    Notes: Summary It is believed that direct hernias are less likely to strangulate because, in contrast to an indirect inguinal hernia, the neck of the direct hernia is wide. For this reason, some surgeons do not repair direct hernias in I elderly patients. We analyzed all incarcerated hernias repaired on an emergency basis during a 3-year period in order to discover the extent of incarcerated direct hernias in our practice. A total of 293 patients with incarcerated hernia were evaluated; of these, 222 were inguinal (193 indirect −86.9%- and 29 direct −13.1%-). The strangulation rate for inguinal hernias was found to be 29.7%. There was a significant difference between indirect and direct inguinal hernias in respect to strangulation rate (32.6% vs 10.3% p = 0.014). However, we did not find any difference between bowel resection rates in incarcerated-strangulated indirect and direct hernias (14/193 −7.3%- vs 2/29 −6.9%-, p = 0.95). Hospitalization time was significantly longer for the patients who developed strangulation than those who did not. The side of direct hernia had no effect on strangulation (10.5% for right-sided vs 10.0% for left-sided, p = 0.97). The only prognostic factor for strangulation and resection in regression analysis was the age-group of the patients (〈 60 vs. 60 or older). At operation the average diameter of the defect in the transversalis fascia was 23.8 mm. The diameter of the defect had no effect on strangulation.

    Notes: Abstract In order to assess the place of HLA-identical allogeneic bone marrow transplantation (BMT) and to compare it to other post-induction therapies, we analyzed patient outcome in intention-to-treat based on the presence or not of an HLA-identical familial donor in young adults with de novo acute myeloid leukemia (AML) in first complete remission (CR). Between 1985 and 1998, 152 consecutive AML patients aged less than 41 years old, seen in our institution, were treated according to 3 different successive protocols (LYLAM85, LAM90, AML10). 144/152 patients entered our prospective study in which they were registered at time of diagnosis for presence or absence of HLA-identical donor and analyzed in intention-to-treat. In this study, 52 patients (36%), who had at least one identical sibling donor (group 1), were offered allogeneic BMT after CR achievement. The 92 patients without donor were allocated to group 2 and were assigned to receive chemotherapy or autologous transplantation as post-remission according to the protocol they were initially included in. Patients from both groups had similar disease characteristics at diagnosis. Karyotypes at diagnosis were defined as low risk (t(8;21) or t(15;17) or chromosome 16 abnormalities(, intermediate risk (normal karyotypes), or high risk (other abnormalities). Overall, 114/152 patients (75%) achieved a CR. Of the 144 eligible patients, 46/52 (88%) with a donor and 68/92 (74%) without a donor achieved a CR. The median follow-up duration of the 144 patients was 21.2 months. The relapse rate was higher in group 2 (56%) than in group 1 (31%). However, the overall survival was not different between patients with and without donor (median survival respectively at 16.7 months and 26.6 months with estimated survival at 5 years respectively at 32% and 34%). Thirty-four patients from group 1 (65%) were actually transplanted in first CR. The probability of 5-year survival for patients receiving effectively allogeneic BMT was 44% and was not significantly better than that of patients who did not. In univariate as in multivariate analysis, karyotypic status was the main prognostic factor for CR achievement (p = 0.002), CR duration (p 〈 0.0001), and overall survival (p 〈 0.0001). There were no significant differences between group 1 and group 2 when survivals were compared with adjustment for karyotypes. We conclude that the availability of an HLA-identical sibling donor did not confer any prognostic advantage in terms of outcome for young adults with AML in first CR. These results make allogeneic BMT process questionable as systemic post-remission therapy in patients with an HLA-identical familial donor.

    Notes: Abstract Background. In patients with early stage breast cancer who have breast-conserving therapy (BCT), the impact of local recurrence on the risk of distant metastasis is still controversial. Local recurrence after BCT is an uncommon event, so it is impossible to determine a standard treatment method by a clinical trial because not enough patients can be enrolled. Methods. Between February 1988 and December 1997, 399 patients with clinical stage I and II breast cancer underwent BCT in our department. Of these 399 patients, 22 developed local recurrence during this period. To assess the relationship between their clinical characteristics and prognosis, we performed a retrospective review of these 22 patients. Results. The 5-year overall survival rate after local recurrence was 66.7%. All four patients who had cutaneous or inflammatory type recurrence developed distant metasta-sis after salvage treatment. Of three patients with multiple recurrence, two developed disseminated disease after salvage treatment. Two of four patients treated by repeat lumpectomy developed further local recurrence after salvage lumpectomy. Conclusion. To improve prognosis in patients with multiple, cutaneous, or inflammatory recurrence, aggressive adjuvant systemic therapy may be required after salvage surgery.

    Notes: Abstract Background. The prognostic significance of c-erb B-2 in breast cancer remains controversial. The aim of this study was to determine the practical prognostic significance of c-erb B-2 protein status in breast cancer extracts, using an enzyme immunoassay. Methods. An enzyme immunoassay was used to measure levels of c-erb B-2 protein prospectively in 360 patients with breast cancer, using cytosol fractions prepared for steroid receptor assay. The status of c-erb B-2 protein was assessed using a cut-off value for positivity of 18 ng/mg protein. Univariate and multivariate analyses were performed. To evaluate the prognostic significance of c-erb B-2 protein status. Results. Levels of c-erb B-2 protein in tumor tissue extract ranged from 0 to 213.0 ng/mg protein (mean, 15.5 ng/mg protein). In 52 tumors (14.4 %) more than 18.0 ng/mg protein was detected, and these tumors were regarded as c-erb B-2 protein-positive. Correlations were found between c-erb B-2 protein positivity and large tumor size (〉3 cm; P = 0.0095), higher histological grade (P 〈 0.0001), estrogen receptor negativity (P 〈 0.0001), and progesterone receptor negativity (P 〈 0.0001). There was also a marginally significant correlation between c-erb B-2 protein positivity and lymph node positivity. Multivariate analysis showed that c-erb B-2 protein status was a significant independent prognostic factor for disease-free survival, being strongly significant in patients with positive lymph nodes. Conclusion. c-erb B-2-positive breast cancers are biologically more aggressive and c-erb B-2 protein status could be a candidate as a prognostic factor for patients with breast cancer, being particularly valuable in patients with positive lymph nodes.

    Notes: Abstract Background. The value of splenectomy for secondary splenic tumors remains unclear. The aim of this study was to disclose the clinical significance of splenectomy for colorectal cancer metastases to the spleen by reviewing our two patients and the 24 other patients reported thus far. Methods. We report two patients with splenic metastasis from colonic cancer. A review of 26 cases, including ours, was conducted. Results. One of our patients had isolated splenic metastasis and is alive with no evidence of disease 14 months after splenectomy, while the other had non-isolated splenic metastasis and died of disseminated disease 17 months after splenectomy. In the 26 patients overall, the outcome of those with isolated splenic metastasis (n = 20) was significantly better than that for those with non-isolated splenic metastasis (n = 6; P = 0.05). There were three long-term (more than 3 years) survivors; all three were patients with isolated splenic metastasis, with the longest survival being 110 months. Patients with mucinous carcinoma showed a better survival rate than patients with other histological types (P = 0.08). In patients with isolated metastasis, metastases after splenectomy occurred in the peritoneum (n = 3), liver (n = 1), and lung (n = 1) within 2 years. Conclusions. Splenectomy may provide long-term survival for patients with isolated colorectal cancer metastasis to the spleen. The mucinous variant may be a favorable prognostic factor after splenectomy. Recurrence after splenectomy is likely to occur within 2 years, mainly in the peritoneum.

    Notes: Abstract Study objective: To review the epidemiology of meningococcal disease in Malta over the period 1994–1998, and to identify factors at presentation and in the management of meningococcal disease which may influence mortality. Design: All admissions with meningococcal disease to a national hospital in a population-based study over the period 1994–1998 were studied retrospectively. Main results: Fifty-six cases were diagnosed over 1994–1998, the incidence rising from 0.8/100,000 to 7.2/100,000 total population (p 〈 0.0001). The median time interval from arrival at hospital to administration of parenteral antibiotic decreased over the 5-year period from 4.4 to 1.2 hours (p = 0.025), with no significant change in the case-fatality rate. There was no association between the time interval from arrival at hospital to parenteral antibiotic administration, and mortality. The following features at presentation were associated with increased mortality: older age (p = 0.03), meningococcaemia compared with meningitis (p = 0.05), shock (p 〈 0.0001), disseminated intravascular coagulation (p = 0.0001), a normal/low white blood cell count (p = 0.0003), a low platelet count (p = 0.0001) and a high serum creatinine (p = 0.003). Conclusions: The upsurge of cases in the population was accompanied by a decrease in intervention time in the general hospital, probably due to increased awareness of the disease. This study did not show a positive relationship between early in-hospital administration of antibiotics and improved survival, probably because antibiotics were given earlier to those with fulminant disease and, with therefore, an inherently worse outcome. Stratification of cases by severity on admission is recommended in future studies.

    Notes: Abstract Host-tumor interactions are primarily controlled by paracrine interactions between adjacent normal host cells and malignant cells. Recent evidence from experimental and clinical neoplasms indicates that neoplasms, or their products, produce levels of circulating pro- and anti-inflammatory cytokines that modulate these local paracrine interactions in such a way that promotes tumor growth. This brief review focuses on several cytokines (interleukin-6, interleukin-10, transforming growth factor-beta, and vascular endothelial growth factor) that have systemic effects in experimental models and are associated with prognosis in patients with colorectal carcinoma. The primary focus of this review is on colorectal carcinoma, but implications for other malignancies are also considered. Colorectal and similar carcinomas may exert systemic control over neoplastic progression by modulating circulating levels of cytokines that then influence the growth of distant metastasis by affecting local paracrine interactions.

    Notes: Abstract Background. The purpose of this study was to investigate the correlation between P-glycoprotein status and outcome in adult patients with high-grade osteosarcomas and soft-tissue sarcomas. Methods. P-glycoprotein status was determined im-munohistochemically in specimens from 28 patients with osteosarcoma and 34 patients with soft-tissue sarcoma. The polyclonal antibody mdr(Ab-1) was used for either decalcified or undecalcified tissue samples which were formalin-fixed and paraffin-embedded. The expression of P-glycoprotein mRNA was also determined by the polymerase chain reaction in 23 fresh sarcoma specimens. P-glycoprotein status was analyzed in relation to the duration of event-free survival. Results. Positivity for P-glycoprotein was found in 29% of the osteosarcomas and 34% of the soft-tissue sarcomas. Consistent results were obtained at both the immunohistochemical and reverse transcriptase-polymerase chain reaction (RT-PCR) levels in 19 of 23 sarcomas (83%). In patients with osteosarcoma, the presence of increased levels of P-glycoprotein was significantly associated with a decreased probability of event-free survival after diagnosis (P = 0.022). In contrast, in patients with soft-tissue sarcoma there was no correlation between the level of P-glycoprotein and prognosis. Conclusions. In patients with high-grade osteosarcomas, the presence of increased levels of P-glycoprotein detected by polyclonal antibody mdr(Ab-1) was associated with a significantly increased risk of adverse events. This association was not found in patients with soft-tissue sarcomas.

    Notes: Abstract Background. Metachronous solitary metastasis of renal cell carcinoma (RCC) to the contralateral adrenal gland is very rare. We assessed the clinocopathological findings of such patients who received adrenalectomy. Methods. We retrospectively reviewed the records of all 495 patients who underwent nephrectomy for RCC; excluding those in stage IV, between 1980 and 1993. Of these patients, 5 who showed metachronous solitary metastasis to the contralateral adrenal gland, and also received adrenalectomy were the subjects of this study. Results. The adrenal metastasis was found between 14 and 132 months (median, 81 months) after nephrectomy. After the solitary adrenalectomy, patient survival ranged from 450 to 2160 days (median, 660 days); 2 patients were alive with no evidence of disease at 660 and 1830 days, respectively, and 3 patients died of this disease, at 450, 480, and 2160 days, respectively, after adrenalectomy. The overall survival rate was 100% at 5 years, 80% at 6 years, 60% at 7 years, and 40% thereafter. The 2 patients with no evidence of disease did not receive steroid supplementation, because they had not received ipsilateral adrenalectomy. No significant difference was observed between survivors and non-survivors in terms of clinicopathological factors such as affected side, location of the tumor, tumor size of primary/metastatic lesion, and stage or grade of primary/metastatic lesion. From the viewpoint of outcome, patients with early recurrence tended to show an unfavorable prognosis compared with prognosis in those with late recurrence. Conclusion. The prediction of outcome in patients with RCC who undergo, adrenalectomy for metachronous solitary metastasis to the contralateral adrenal gland is difficult. Although the factors that affect prognosis are uncertain, long-term observation for unusual metachronous metastasis to the contralateral adrenal gland is mandatory in patients with RCC.

    Notes: Abstract  Early identification of patients likely to deteriorate post-hepatic portoenterostomy for biliary atresia (BA) would be beneficial. α-Glutathione-s-transferase (α-GST) is a serologic marker of reactive hepatocellular damage because of its low molecular weight, uniform hepatic distribution, high cytosol concentration, and short half-life. We evaluated whether serum α-GST in post-surgical BA patients correlates with liver function (LF) and investigated its potential as a medium- to long-term marker of prognosis. Postoperative BA patients (n = 30; mean age: 11.8 ± 3.7 years) were divided into three groups based on average LF over the 3 months prior to this study. Group I (n = 8) were jaundice-free and had normal LF. Group II (n = 12) had moderate liver dysfunction, and group III (n = 10) had severe liver dysfunction. Serum α-GST was determined using a specific ELISA. Tissue α-GST was determined immunohistochemically, using liver needle-biopsy specimens. Bile lakes were found in 5 group II patients and 5 group III patients. Serum α-GST was significantly higher in group II (20.7 ± 8.4 ng/ml) than in groups I (4.7 ± 1.3 ng/ml) and III (8.0 ± 1.2 ng/ml) (P 〈 0.0001) and was highest in group II subjects with bile lakes. In control liver specimens α-GST distribution was weak but uniform throughout normal liver lobule hepatocytes. In group II there was strong staining in centrilobular hepatocytes, and in group III α-GST was only found in regenerative nodules. We conclude that α-GST may be a more sensitive indicator of hepatocellular damage in BA because its distribution is correlated to the proportion of functioning liver tissue present. This is the first report of this relationship, which has great implications for group II subjects because a sudden shift in concentration of α-GST may be a better predictor of impending hepatic dysfunction than conventional LF tests.

    Notes: Abstract  Clinical and histologic findings from 206 patients operated upon for extrahepatic biliary atresia (EHBA) are analyzed in order to define the prognosis of patients with EHBA. The prospective study took into consideration both initial fibrosis of the liver and the morphology of the porta hepatis (PH) at surgery. Kaplan-Meier survival estimates and statistical calculations demonstrated a relationship between long-term survival and histologic findings in the liver and porta hepatis. The efficacy of HPE is significantly influenced by the morphology of the PH and to a lesser extent by the initial liver fibrosis. Surgery should thus achieve pattern 1 morphology of the PH, but this is problematic because of the close relationship of the vascular and biliary structures in its two lateral zones.

    Notes: Abstract  Glasgow Coma Scale (GCS) scores on admission may be predictors of outcome in patients with brain injuries. This study correlated the outcomes of children with traumatic brain stem lesions with their initial GCS scores and morphological patterns of injury as shown on computed tomography (CT) or magnetic resonance (MR) imaging. During the last 16 years, we have treated 1,108 children with brain injuries. The entire series included only 21 (1.9%) children who had clinical signs of brain stem lesions with morphological correlates on CT or MR imaging. Clinical findings were assessed according to the GCS and compared with scores on the Glasgow Outcome Scale (GOS). Of these 21 children, 16 (76%) had morphological lesions seen on CT scans. In 5 (24%) of the children only the MR images revealed brain stem lesions and their CT scans were negative. Generalized severe brain swelling was present in 6 cases (28%). There was a significant difference in GOS scores between patients with initial GCS scores of 3 and 4 and those with GCS scores between 5 and 7 (P〈0.02). Children with intracranial pressure higher than 40 mmHg had poorer outcomes than patients whose intracranial pressure was lower, but the differences were not significant. Outcome did not correlate significantly with morphological patterns of injury or the presence of extracranial injuries. The GCS is a reliable indicator of severity of injury and of outcome in children with brain stem injuries. MR imaging was more sensitive than CT in detecting brain stem lesions.

    Notes: Abstract  This review evaluates the contribution of prenatal diagnosis to the understanding of intracranial cysts. We describe the outcome of 54 fetuses in which prenatal investigations indicated the presence of such lesions. The cysts were diagnosed between 20 and 30 weeks of gestation. Most (63%) were supratentorial and interhemispheric. There was only a single sylvian cyst. In the infratentorial compartment, median retrocerebellar cysts were predominant. Incisural cysts accounted for 14.8% of the series. Nine pregnancies were interrupted because of the presence of associated brain disorders. Forty-five children are alive. Thirty-four had neuropsychological tests. Cysts rarely progressed, most frequently stabilized and often regressed postnatally. Hydrocephalus was rare. In two cases delivery was precipitated at 36 weeks to allow urgent treatment of rapidly evolving cysts. Thirteen children (28.2%) were treated postnatally, in general for developing cysts. The median follow-up for the whole series exceeds 4 years. Behavior, neurological development, and intelligence are normal in 88% of the cases, and 91% have a normal neurological status. Prognosis at the time of the prenatal consultation was correct in 89% of the cases. We emphasize the value of prenatal magnetic resonance imaging and karyotype studies to limit risks of incorrect prognosis.

    Notes: Abstract  A care network has been created in the Paris area according to two criteria – the continuity and the specificity of the care, with a single place to manage pediatric neurosurgical emergencies. This network makes possible research about brain-injured children. Until recently, the ”Kennard principle”, that is, the assumption that recovery after similar lesions is greater in children than in adults has been supposed to be always true. In fact, if the lesions are diffuse, recovery is not greater in children compared with adults, or in younger children compared with older ones: the prognosis depends on the remaining ability to learn new practices. Normal IQ does not mean absence of sequelae. The cognitive deficits are very similar to those found in adults at the acute phase. For instance, visuo-spatial neglect appears as rather frequent when systematically looked for. The final assessment of outcome after childhood traumatic brain-injury should be done only after several years.

    Description / Table of Contents: Abstract A severe course of alcohol withdrawal has been observed in 28% of patients in a neurological intensive care unit due to complicating central nerve system (CNS) diseases. In any atypical alcoholic delirium, especially with focal neurological signs, partial seizures, or decreased level of consciousness, CNS diseases like meningoencephalitis, intracranial hemorrhage, or central pontine myelinolysis must be diagnosed by computed tomography (CT) scan and cerebral spinal fluid (CSF) tap. The diagnostic and prognostic value of CT scan and CSF analysis was examined in 32 persons with alcohol withdrawal syndrome or delirium tremens. Neurological complications and cerebral convulsions at the beginning of delirium tremens appear to predispose the patient to a protracted clinical course and necessary mechanical ventilation. Blood-CSF barrier permeability is increased in 70% of alcohol withdrawal patients and that also seems to be a marker of a prolonged clinical course. Cerebral atrophy as shown in CT scan does not play a role in predicting clinical course. In our experience, CT examination or lumbar puncture is not necessarily recommended if clinical signs are typical for alcohol delirium.
    Notes: Zusammenfassung Der Verlauf intensivmedizinisch behandelter Alkoholdelirien ist in 28% der Fälle durch eine begleitende ZNS-Erkrankung erschwert. Durch das Delir mitigierte neurologische Begleiterkrankungen, wie Meningoenzephalitiden, intrakranielle Hämatome oder eine zentrale pontine Myelinolyse können bei Vorliegen einer atypischen deliranten Symptomatik durch eine neurologische Zusatzdiagnostik mit Hilfe von CCT/MRT und Liquoranalyse ausreichend diagnostiziert werden. Der diagnostische und prognostische Wert dieser Zusatzdiagnostik wurde an 32 neurologisch-intensivmedizinisch behandelten Alkoholikern im Delir untersucht. Das Auftreten zerebraler Komplikationen korreliert dabei ebenso wie ein initialer Grand-mal-Anfall mit einem protahierten Verlauf und Beatmungspflichtigkeit. Eine Blut-Liquor-Schrankenstörung ließ sich bei 70% nachweisen. Es finden sich Hinweise für einen verlängerten Krankheitsverlauf dieser Patienten. Dem alleinigen Nachweis einer zerebralen Atrophie im CCT/MRT kommt dagegen kein prognostischer Wert hinsichtlich des Delirverlaufes zu. Ein Alkoholdelir mit jedoch typischem klinischem Bild erfordert nach unseren Ergebnissen keine bildgebende oder liquoranalytische Untersuchung.

    Description / Table of Contents: Summary Paraneoplastic neurological syndromes are rare diseases that occur in relation to cancer. Supporting the hypothesis of an autoimmune mechanism, specific antineuronal antibodies have sometimes been detected. The current possibilities for treatment are limited. A female patient, aged 57, suffering from a breast cancer, developed a severe paraneoplastic cerebellar syndrome and limbic encephalitis within a few weeks. It is possible that the impressive partial remission that occurred during the ensuing 6 months was not due to therapy. Although the patient was still bound to a wheelchair, discharge from hospital was possible because she was still able to perform daily tasks by herself. A recurrence of the cerebellar symptoms with mild alterations of mental status occurred 2 months later but again showed a good remission.
    Notes: Zusammenfassung Paraneoplastische neurologische Syndrome sind seltene Erkrankungen in Assoziation mit einem Tumor, die bei vermutetem Autoimmunmechanismus mit antineuronalen Antikörpern einhergehen können und deren Verlauf therapeutisch nur bedingt beeinflussbar ist. Berichtet wird von einer 57-jährigen Patientin mit Mammakarzinom, die in engem zeitlichen Rahmen sowohl eine schwere paraneoplastische Zerebellopathie als auch eine limbische Enzephalitis entwickelte. In unklarem Zusammenhang zur Therapie kam es innerhalb von 6 Monaten zu einer vergleichsweisen guten Rückbildung beider Syndrome, so dass zwar noch eine partielle Rollstuhlpflichtigkeit bestand, bei weitgehender Selbständigkeit aber eine Entlassung nach Hause möglich war. Ein Rezidiv 2 Monate später mit im Vordergrund stehender zerebellärer Symptomatik verlief ebenfalls günstig.

    Notes: Abstract We report herein the case of a 59-year-old man found to have adenosquamous carcinoma of the remnant stomach which demonstrated rapid progression. The patient was admitted to our hospital to undergo surgery for a papillary tumor of the remnant stomach. Total resection of the remnant stomach with lymph node dissection was performed, and pathological examination confirmed a diagnosis of adenosquamous carcinoma with invasion into the muscularis propria and lymph node metastasis around the perigastric areas. Multiple liver metastases were found 6 months after the operation, for which a right hepatectomy was performed with curative intent; however, he died 2 months later due to lymphangitis carcinomatosa of the lung.

    Notes: Background. During the 1970s, a special type of Gastric Cancer with excellent prognosis (early gastric cancer; EGC) was identified by the Japanese Research Society for Gastric Cancer. EGC has been defined as a tumor which invades the mucosa and/or submucosa, regardless of the lymph node status. Using this definition, we identified an initial phase of tumor development which could be treated both endoscopically and surgically. Methods. We examined 412 EGC patients, recruited between 1976 and 1999, with an average follow-up of 9 years. All tumors were classified according to the macroscopic and microscopic criteria proposed by the Japanese Society of Gastroenterological Endoscopy (JSGE) and Lauren, respectively. The infiltrative growth pattern was evaluated according to Kodama's classification. Only tumor-related death was considered as an end-point of interest for the survival analysis. Results. Submucosal tumors (P = 0.008), Pen A (see definition below) type disease (P = 0.0001), and lymph node-positive cancers (P = 0.0002) were significant prognostic factors on univariate analysis. Moreover, bivariate analysis showed that the worst prognosis, in terms of survival, was for patients with nodal involvment, submucosal invasion, and node-positive and Pen-A type cancer. The abbreviation Pen, penetrating, indicates a lesion with a diameter of less than 4 cm, which invades the submucosa diffusely. Pen A type EGC represents a subgroup of tumors which infiltrates the submucosa extensively, with nodular masses, causing the complete destruction of the muscularis mucosae. Conclusion. In our series, Pen A type was an important prognostic factor (hazard ratio; HR, 8.32; 95% confidence interval [CI], 3.49–19.86. For this reason, we believe it is important to evaluate the infiltration into the wall in all patients with EGC, paying particular attention to the growth pattern of the neoplasm. Moreover, submucosal Pen A type tumors had a considerably worse prognosis and this finding was reinforced when lymph node metastases coexisted. We suggest, therefore, that surgical treatment with at least a D2 lymphadenectomy is performed in all these patients, as the lesions must be considered to be advanced, no longer being EGC.

    Notes: Gastric carcinoid tumors associated with chronic atrophic gastritis type A have been reported to show good prognosis, because invasion and metastasis are rare. We report a case of gastric carcinoid tumor associated with hypergastrinemia that showed no malignant changes for 12 years. A 15-year-old man with abdominal discomfort underwent endoscopic examination. A polypoid lesion was detected on the atrophic mucosa of the fundus, and was diagnosed as a carcinoid tumor. Serological examination revealed a high level of anti-parietal-cell antibody, suggesting that the patient had chronic atrophic gastritis type A. The tumor was treated by endoscopic mucosal resection. Follow-up examinations were performed for 12 years, but showed no recurrence. This case confirms that gastric carcinoid tumors associated with chronic atrophic gastritis type A may have a good prognosis.

    Notes: Background. This clinicopathological study evaluated the utility of serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 as predictors of locoregional recurrence and long-term disease-free survival in patients with gastric cancer. Methods. During the period January 1989 to December 1994, 485 patients with primary gastric cancer were evaluated. Gastrectomies were performed in 434 patients. Prognostic factors were analyzed by the Kaplan-Meier method and multivariate analysis, using Cox regression. Results. Elevated serum CEA and CA19-9 levels were observed in 92 of the 485 patients (19.0%), and in 95 of the 435 patients (21.8%), respectively, and both markers were elevated in 29 of these 435 patients (6.7%). Elevated serum CEA and CA19-9 levels correlated well with lymph node metastasis, lymphatic invasion, vessel invasion, stage grouping, depth of invasion, and curability. Patients with elevated serum CEA levels were at significantly higher risk of having all recurrence factors than were those with normal serum CEA levels. Patients with elevated serum CA19-9 levels were at significantly higher risk of having peritoneal metastases and distant metastases than were those with normal serum CA19-9 levels. A significant difference in the cumulative survival curves of patients was demonstrated between those with elevated and those with normal serum CEA or CA19-9 levels, even for patients at the same disease stage (stage III). Patients with elevated levels of both markers had a significantly worse prognosis than patients in whom the levels of both markers were normal. In patients who underwent gastrectomy, elevated serum CEA levels either preoperatively or within 3 weeks after gastrectomy were associated with significantly worse prognosis than were normal levels. When the cutoff level of serum CEA was increased to 10 ng/ml, serum CEA, age, lymph node metastasis, and surgical stage grouping were selected as independent prognostic factors by multivariate analysis of 14 prognostic factors, using Cox regression. Conclusion. Serum CEA and CA19-9 levels provide additional prognostic information in patients with primary gastric cancer. In particular, an elevated serum CEA level provides additional prognostic information and is a useful indicator of curability in patients who undergo gastrectomy. Serum CEA level is an independent prognostic factor in patients with primary gastric cancer.

    Notes: Background. Although many authors have investigated the prognostic factors of gastric cancer, there are few comprehensive studies on the prognosis of patients with extensive lymph node metastasis. The aim of this study was to clarify the prognostic factors of gastric cancer with extragastric lymph node metastasis, using multivariate analysis. Methods. The study population consisted of 121 patients who had undergone radical gastrectomy and extended lymph node dissection (D2, D3) for gastric cancer with extragastric lymph node metastasis. We examined 18 clinicopathologic factors, including the type of gastrectomy, tumor size, depth of wall invasion, status of lymph node metastasis, and stage of disease. Survival rates were analyzed by the Kaplan-Meier and Mantel-Cox methods, and multivariate analysis was done using the Cox proportional hazards model. Results. The overall 5-year survival rate was 32%, and the 5-year survival rate after curative gastrectomy was 37%. Overall survival rate was associated with the type of gastrectomy, stage of disease, operative curability, tumor size, depth of wall invasion, and anatomical distribution of positive nodes, whereas the survival rate after curative gastrectomy was correlated with the type of gastrectomy, stage of disease, tumor size, gross type, and depth of wall invasion. Independent prognostic factors were operative curability and depth of wall invasion, and survival after curative gastrectomy was influenced only by the depth of wall invasion (mucosa and submucosa [T1], muscularis and subserosa [T2] vs serosa [T3]). Conclusion. In patients with gastric cancer with extragastric lymph node metastasis, independent prognostic factors after gastrectomy were operative curability and depth of wall invasion. Long-term survival can be achieved when the patients have no serosal invasion (T1, T2) and are treated by curative gastrectomy.

    Notes: Abstract  Interleukin(IL)-2 is a T helper (Th) 1 type cytokine that has been shown to play an important role in antitumour immune responses. In this study, the prognostic significance of serum IL-2 levels was investigated in 60 advanced non-small-cell lung cancer (NSCLC) patients. IL-2 serum levels were determined before chemotherapy, at the end of chemotherapy and during follow-up, using a commercially available enzyme-linked immunoadsorbent assay kit. The results were analysed according to the response to therapy and were used to generate a model predicting overall survival and time to treatment failure. All 60 patients were shown to have higher IL-2 serum levels than controls (P 〈 0.0001). Stage IV patients had significantly lower IL-2 levels than stage III patients (P 〈 0.0001), although they were still significantly higher than controls (P 〈 0.0001). It is interesting that, when patients were divided into responders and non-responders according to the response to therapy, the former were shown to have significantly higher pre-chemotherapy levels than the latter (P 〈 0.0001). Moreover, a further significant increase in IL-2 serum levels (P=0.004) and a significant decrease (P 〈 0.0001) were shown in responders and non-responders, respectively at the end of the therapy. Using univariate and multivariate analyses, both overall survival and time to treatment failure were shown to be affected by the mean pathological levels of IL-2. Furthermore, the prognostic significance of the serum level of IL-2 was confirmed by the stepwise regression analysis. In conclusion, determination of pre-treatment IL-2 serum levels was shown to be of independent prognostic utility in patients with advanced NSCLC; therefore, its possible use for prediction of outcome is proposed.

    Notes: Abstract The αvβ3 integrin has emerged as a key mediator in angiogenesis. Its role in tumor-induced angiogenesis is supported by its up-regulation in vivo in the vasculature of a number of different types of carcinoma. The potential clinical significance of αvβ3 expression on blood vessels in carcinomas is suggested by its association with tumor progression. Currently no information is available about the clinical significance of αvβ3 expression on the vasculature of lesions of melanocytic origin. Since we have previously found that αvβ3 expression on melanoma cells in primary lesions is associated with a poor prognosis, in the present study we have compared αvβ3 expression on blood vessels and on cells of melanocytic origin in nevi and in malignant melanoma lesions. In addition we have examined the lesions for expression of the αv subunit to gain information on the regulation of αvβ3 expression on endothelial cells and on cells of the melanocyte lineage. αvβ3 expression on endothelial cells and on melanocytic cells was a relatively sensitive and specific marker for malignant lesions. However, αvβ3 expression on endothelial cells in primary melanoma lesions was not associated with the prognosis of the disease. The αv subunit and the αvβ3 complex were differentially expressed on endothelial cells and on melanocytic cells, implying that different regulatory pathways control their expression. This finding may account for the differential clinical significance of αvβ3 expression on tumor vasculature and on melanoma cells we observed in our patient cohort. Lastly, αvβ3 may be a useful target for immunotherapeutic approaches in melanoma because of its high expression on the vasculature of all metastatic lesions tested and its restricted distribution in normal tissues.

    Notes: Abstract  Purpose: The aim of this work was to evaluate the prognostic significance of DNA image cytometry in thymoma. Patients and methods: Image cytometric studies with an automatic video-based analysis system (LEYTAS) were carried out on 47 archival specimens from 36 patients with thymomas who underwent operation at a single institution from 1954 to 1992. The significance of aneuploidy DNA-content (5c-exceeding events), and nuclear size on stage and survival were evaluated. The median follow-up was 52.7 (6–164) months. Results: Masaoka's stage was predictive of aneuploidy (P 〈 0.01) and disease-free survival (P 〈 0.015). In stage I 18% of the tumors were aneuploid, in stage II 78%, in stage III 85% and in stage IV 100%. The occurrence of 5c-exceeding events was associated with both decreased disease-free survival (P 〈 0.01) and overall survival (P = 0.013). Nuclear size was not significantly correlated to stage. Under multivariate analysis, aneuploidy and DNA content failed to attain independent significance for stage, performance status, and histology. Conclusion: DNA image cytometry may provide additional information about the prognosis of resected thymoma.

    Notes: Abstract The deletion of blood group ABH isoantigens on tumor tissues has been reported to be an adverse prognostic marker for patients with various solid tumors. In the present study, we evaluated the prognostic value of altered expression of ABH isoantigens in colorectal carcinomas. Using monoclonal antibodies, the expression of A, B, and H antigens was assessed by immunohistochemistry on paraffin-embedded carcinoma samples from 82 patients who had undergone surgery for colorectal cancer. ABH isoantigens were found to be deleted in 36 carcinomas (43.9%) and expressed in 46 (56.1%). Univariate and multivariate analysis using a logistic regression model revealed that N factor (lymph node metastasis) and blood group type were independently related to the expression of ABH isoantigens. In contrast to previous reports on other cancers, patients whose colorectal carcinomas express ABH isoantigens had a poorer prognosis than those whose carcinomas showed deletion of ABH isoantigens (P = 0.0008). The expression of ABH isoantigens was an independent prognostic variable, in addition to T (depth of tumor invasion), N, and M (distant metastasis) factors, as shown by means of Cox regression analysis. In conclusion, the expression of ABH isoantigens in carcinoma tissue is an important poor prognostic factor in patients with colorectal cancer. This variable needs to be considered in the design of future trials of therapy.

    Notes: Abstract Objective: To determine the epidemiological trends, spectrum of etiologies, morbidity and mortality of acute renal failure (ARF) in patients over 80 years old.¶Design: Historical cohort analysis.¶Setting: Intensive care unit (ICU) of nephrology, Tenon Hospital, Paris.¶Patients and participants: The criteria of inclusion was ARF, defined on the basis of a creatinine value over 120 μmol/l, in patients over 80 years of age admitted between October 1971 and September 1996. When moderate chronic nephropathy was pre-existing, ARF was defined by the increase of at least 50 % over the basal creatininemia.¶Measurements and results: Three hundred and eighty-one patients over 80 years of age were included. The etiology and mechanism of ARF are detailed. 29 % of the patients received dialysis. Global mortality at the hospital was 40 %. Factors significantly associated with a poor prognosis are identified. Mean survival after hospitalization was 19 months.¶Conclusion: The frequency of admission to ICUs for ARF in patients older than 80 years seems to be on the increase. Mortality is less severe than expected. These patients could benefit from the renal replacement therapy of modern intensive care medicine.

    Notes: Abstract Objectives: To describe risk factors for the development of acute renal failure (ARF) in a population of intensive care unit (ICU) patients, and the association of ARF with multiple organ failure (MOF) and outcome using the sequential organ failure assessment (SOFA) score. Design: Prospective, multicenter, observational cohort analysis. Setting: Forty ICUs in 16 countries. Patients: All patients admitted to one of the participating ICUs in May 1995, except those who stayed in the ICU for less than 48 h after uncomplicated surgery, were included. After the exclusion of 38 patients with a history of chronic renal failure requiring renal replacement therapy, a total of 1411 patients were studied. Measurements and results: Of the patients, 348 (24.7 %) developed ARF, as diagnosed by a serum creatinine of 300 μmol/l (3.5 mg/dl) or more and/or a urine output of less than 500 ml/day. The most important risk factors for the development of ARF present on admission were acute circulatory or respiratory failure; age more than 65 years, presence of infection, past history of chronic heart failure (CHF), lymphoma or leukemia, or cirrhosis. ARF patients developed MOF earlier than non-ARF patients (median 24 vs 48 h after ICU admission, p 〈 0.05). ARF patients older than 65 years with a past history of CHF or with any organ failure on admission were most likely to develop MOF. ICU mortality was 3 times higher in ARF than in other patients (42.8 % vs 14.0 %, p 〈 0.01). Oliguric ARF was an independent risk factor for overall mortality as determined by a multivariate regression analysis (OR = 1.59 [CI 95 %: 1.23–2.06], p 〈 0.01). Infection increased the risk of death associated with all factors. Factors that increased the ICU mortality of ARF patients were a past history of hematologic malignancy, age more than 65 years, the number of failing organs on admission and the presence of acute cardiovascular failure. Conclusion: In ICU patients, the most important risk factors for ARF or mortality from ARF are often present on admission. During the ICU stay, other organ failures (especially cardiovascular) are important risk factors. Oliguric ARF was an independent risk factor for ICU mortality, and infection increased the contribution to mortality by other factors. The severity of circulatory shock was the most important factor influencing outcome in ARF patients.

    Notes: Abstract We performed a study to investigate differences and similarities between patients with Sneddon's syndrome and those with primary antiphospolipid syndrome (PAS), by clinical follow-up, magnetic resonance imaging (MRI) and angiography. Nine patients with Sneddon's syndrome and 11 patients with PAS were assessed at diagnosis and followed for a mean fo 6 years. The clinical and MRI findings indicated that Sneddon's syndrome and PAS are distinct entities. Patients with Sneddon's syndrome had a progressive clinical course with increasing disability and cognitive deterioration; patients with PAS had a more benign course. Infarcts in territories of the main cerebral arteries were frequent in PAS, while leukoaraiosis and smaller lacunar infacts were more comon in Sneddon's syndrome. In 3 of 7 women initially diagnosed with PAS, the diagnosis was changed to systemic lupus erythematosus during follow-up. Differential diagnosis of Sneddon's syndrome and PAS is important, as early therapy is effective for the latter, more benign, condition.

    Notes: Abstract Purpose: p21WAF1, a cyclin-dependent kinase inhibitor, is an important mediator of the cell-cycle arrest and tumor suppression induced by the protein p53. Although alterations of the p53 gene and its overexpression are frequent in most malignancies, including non-small-cell lung cancer (NSCLC), and may be associated with poor patient prognosis, the clinical utility of p21WAF1 expression in NSCLC has not been established. Methods: We have used a commercial enzyme-linked immunosorbent assay (ELISA) kit for p21WAF1 to test soluble extracts of 54 NSCLC specimens with known clinicopathological properties. Results: There was no correlation between p21WAF1 and p53 concentrations, the latter being determined by a time-resolved immunofluorometric assay developed in-house. Furthermore, p21WAF1 levels were not associated with patient age, tumor/node/metastasis (TNM) stage, lymph node metastasis, histological grade or type, or smoking history, in Mann-Whitney analysis. χ2-tests, based on cutoffs equal to the 25th, 50th, or 75th percentiles of the p21WAF1 distribution, similarly did not reveal any statistically significant associations between p21WAF1 and other clinicopathological variables. Because of the small number of patients and the median follow-up of only 18 months, a meaningful survival analysis could not be performed. Conclusion: In summary, this preliminary study suggests that ELISA-quantified p21WAF1 levels in NSCLC extracts are weaker than p53 in terms of prognostic value and do not contribute to the further subclassification of patients.

    Notes: Abstract Background/aims: The family of erbB receptors includes four transmembrane glycoproteins with tyrosine kinase activity. These receptors are widely expressed in normal tissues, but they also have been implicated in the development of several human adenocarcinomas. c-erbB-3/HER-3 has been detected to a greater or lesser extent in many tissues from the digestive, urinary, reproductive and respiratory tracts. The overexpression of c-erbB-3/HER-3 protein has also been shown in 53%–88% of colorectal adenocarcinomas. In this study we investigated the expression of the c-erbB-3/HER-3 gene product in colorectal tumour samples, and compared the results obtained with several clinicopathological parameters, including the survival of patients. Methods: Paraffin-embedded tissue sections were analysed immunohistochemically, using monoclonal antibody RTJ1 to human erbB-3 protein. Antibody RTJ1 specificity was confirmed by immunoprecipitation followed by Western blotting analysis. Amplification of the erbB-3 oncogene was tested by dot-blot hybridization. Results: Adenocarcinomas of the colon were positive for erbB-3 protein in 78% of samples examined. Dot-blot analysis showed no amplification of the erbB-3 gene in colon adenocarcinomas. Statistical analysis showed that patients with tumours that could not be stained for erbB-3 protein survived significantly longer (P 〈 0.05) than patients with tumours staining positive for the erbB-3 protein. A Cox proportional-hazards model with stepwise variable selection identified age, sex and erbB-3 expression as important prognostic factors. Conclusion: These findings demonstrate that erbB-3 protein expression could serve as a prognostic factor in colorectal malignancies.

    Notes: Abstract Objective: To examine the incidence, risk factors, aetiologies and outcome of the various forms of the septic syndromes (the systemic inflammatory response syndrome [SIRS] sepsis, severe sepsis, and septic shock) and their relationships with infection.¶Design: Review of published cohort studies examining the epidemiology of the septic syndromes, with emphasis on intensive care unit (ICU) patients.¶Results: The prevalence of SIRS is very high, affecting one-third of all in-hospital patients, and 〉 50 % of all ICU patients; in surgical ICU patients, SIRS occurs in 〉 80 % patients. Trauma patients are at particularly high risk of SIRS, and most these patients do not have infection documented. The prevalence of infection and bacteraemia increases with the number of SIRS criteria met, and with increasing severity of the septic syndromes. About one-third of patients with SIRS have or evolve to sepsis. Sepsis may occur in approximately 25 % of ICU patients, and bacteraemic sepsis in 10 %. In such patients, sepsis evolves to severe sepsis in 〉 50 % of cases, whereas evolution to severe sepsis in non-ICU patients is about 25 %. Severe sepsis and septic shock occur in 2 %–3 % of ward patients and 10 %–15 % or more ICU patients, depending on the case-mix; 25 % of patients with severe sepsis have shock. There is a graded severity from SIRS to sepsis, severe sepsis and septic shock, with an associated 28-d mortality of approximately 10 %, 20 %, 20 %–40 %, and 40 %–60 %, respectively. Mortality rates are similar within each stage, whether infection is documented or not, and microbiological characteristics of infection do not substantially influence outcome, although the source of infection does. While about three of four deaths occur during the first months after sepsis, the septic syndromes significantly impact on long-term outcome, with an estimated 50 % reduction of life expectancy over the following five years. The major determinants of outcome, both short-term and long-term, of patients with sepsis are the severity of underlying diseases and comorbidities, the presence of shock and organ failures at onset of sepsis or evolving thereafter. It has been estimated that two-thirds of the overall mortality can be attributed to sepsis.¶Conclusions: The prevalence of sepsis in ICU patients is very high, and most patients have clinically or microbiologically documented infection, except in specific subset of patients. The prognosis of septic syndromes is related to underlying diseases and the severity of the inflammatory response and its sequelae, reflected in shock and organ dysfunction/failures.

    Notes: Abstract Objective: To investigate procalcitonin (PCT) levels in patients undergoing cardiopulmonary bypass (CPB) in order to assess the prevalence and prognostic capacity of elevated PCT levels following CPB in open heart surgery.¶Design: prospective observational study in consecutive patients.¶Setting: Twenty-four-bed ICU, department of thoracic and cardiovascular surgery, university hospital.¶Patients: Seven hundred and twenty two patients, 691 of whom underwent CPB, i. e., 476 had coronary bypass surgery (CABG), 130 valve replacement, 34 combined CABG and valve replacement, and 23 thoracic aortic surgery.¶Interventions: Standard perfusion techniques were used with cardioplegic arrest and mild hypothermia (28–32 °C). With the exception of thoracic aortic procedures, full–flow perfusion was performed.¶Measurements and results: PCT was measured prior to surgery and daily thereafter until ICU discharge or death. PCT significantly increased at day 1 postoperatively compared to baseline values (0.25 ± 1.65 vs 6.49 ± 22.0 ng/ml, p 〈 0.005). However, in 55.1 % of patients PCT was below 1.0 ng/ml. In 12.8 % of CABG patients PCT was increased to 〉 5.0 ng/ml, compared to 39 % in valve patients and 35 % of patients with aortic surgery. An elevated PCT level 〉 1.0–5.0 ng/ml at day 1 was highly predictive of mortality (P 〈 0.03, vs 〈 1.0 ng/ml), with an additional accuracy when levels 〉 5.0 ng/ml were measured (P 〈 0.002 vs 〈 1.0 ng/ml).¶Conclusions: These results provide evidence that PCT might serve as an early prognostic marker in patients undergoing CPB in open heart surgery. It may be worth considering immunomodulating approaches in patients presenting elevated PCT levels in the early phase after CPB.

    Notes: Abstract. The aim of this study was to evaluate the therapeutic effect more accurately and predict the prognosis of treated non-small cell lung cancer by using contrast-enhanced magnetic resonance imaging (CE-MRI). Contrast-enhanced computed tomography (CE-CT) and CE-MRI were examined 90 non-small cell lung cancer patients treated with conservative therapies. Enhancement patterns of CE-MRI were classified into three types: peripheral; mottled; and homogeneous. Reduction ratio of tumor size (RRT) based on the World Health Organization response criteria and a new response rate; reduction ratio of viable tumor size (RRVT) which evaluates not only the reduction of tumor size but also changes in necrosis and/or cavity size, were evaluated. Changes of enhancement pattern were compared and correlated with pathological diagnosis. The RRTs, RRVTs, and interobserver agreements evaluated by all modalities were compared. The RRTs and RRVTs in each subgroup were correlated and compared with prognoses. Change of enhancement pattern depended on therapy had no tendency (p = 0.06). Enhancement pattern had significant correlation with pathological diagnosis (p 〈 0.0001). Partial response (PR) case of RRVT had significant difference between imaging techniques (p = 0.04). The RRVT of other cases and RRT had no significant difference. Interobserver agreements of RRT and RRVT were almost perfect (ϰ≥ 0.93). Prognosis had better correlation with RRVT than with RRT. Differences of relapse-free survival and survival between patients considered as having no change (NC) by RRT and PR by RRVT (NC-PR) and patients considered as having NC by RRT and RRVT were significant (p = 0.03, p = 0.01). There were no significant differences of relapse-free survival and survival between NC-PR patients and patients considered as having PR by RRT and RRVT. The CE-MRI technique could accurately evaluate the therapeutic effect and predict the prognosis of treated non-small cell lung cancer.

    Description / Table of Contents: Abstract Undifferentiated small-cell hepatoblastoma (HB) is a rare malignant tumor of childhood. The cell of origin is supposed to be a pluripotential, probably entodermal, stem-cell. Differential diagnosis of this type of HB is difficult among the group of small round and blue cell malignant tumors of children. The immunohistochemically determined coexpression of cytokeratin 8, 18, and 19 and of vimentin and actin, regularly in the absence of α-fetoprotein expression may be diagnostically helpful. We present the case of an undifferentiated small-cell HB of a 15-month-old girl with agenesis of the right kidney. As morphological peculiarity the tumor presented disseminated histiocytic giant cells.
    Notes: Zusammenfassung Undifferenzierte kleinzellige Hepatoblastome (HB) zählen zu den seltenen malignen Tumoren der Leber im Kindesalter. Da der Tumor in der Regel kein α-Fetoprotein exprimiert, ist der Nachweis von Zytokeratin 8, 18 und 19 sowie Vimentin und Aktin diagnostisch wegweisend. Als Ausgangszelle wird eine pluripotente, wohl entodermale Stammzelle vermutet. In der Gruppe der klein-, rund- und blauzelligen malignen Tumoren des Kindesalters bietet diese Variante des HB differenzialdiagnostische Schwierigkeiten. Wir berichten über ein undifferenziertes kleinzelliges HB eines 15 Monate alten weiblichen Kleinkindes mit Agenesie der rechten Niere. Als morphologische Besonderheit des Tumors werden disseminierte histiozytäre Riesenzellen beschrieben.

    Description / Table of Contents: Summary A total of 123 manifestations (97 primary tumours and 26 metastases) of neuroendocrine tumours of the gastrointestinal tract observed in 95 patients was investigated for the prognostic value of clinical, histological and DNA cytophotometric parameters. Metastases almost exclusively occurred among ileal carcinoids, which also were responsible for all 14 cases of lethal outcome observed during the follow-up period of mean 42 months. Aneuploid DNA values could be determined significantly more frequently among ileal than in non-ileal carcinoids and showed – upon analysis of the total group of gastrointestinal neuroendocrine tumours – a significant correlation to lethal course of disease. In addition, among 18 cases with primary and secondary carcinoid manifestations available for DNA cytophotometry, an association between the DNA content of metastatic neuroendocrine tumours and prognosis came to light. When applicated to the group of ileal neoplasms, however, the parameter DNA content did not allow a better prognostic assessment.
    Notes: Zusammenfassung Untersucht wurden 123 Manifestationen (97 Primärtumoren und 26 Metastasen) von bei 95 Patienten beobachteten neuroendokrinen (NE-)Tumoren des Gastrointestinaltrakts auf die prognostische Bedeutung verschiedener klinischer, histologischer und DNA-zytophotometrischer Parameter. Metastasen traten fast ausschließlich bei ilealen Karzinoiden auf, denen auch sämtliche 14 während der durchschnittlichen Nachbeobachtungszeit von 42 Monaten aufgetretenen letalen Erkrankungsverläufe zuzuordnen waren. Aneuploide DNA-Verteilungsmuster wurden signifikant häufiger bei ilealen als bei nichtilealen Karzinoiden angetroffen und waren – bezogen auf die Gesamtgruppe – signifikant mit tödlichem Krankheitsausgang korreliert. Darüber hinaus zeigte sich bei 18 Fällen mit DNA-zytophotometrisch auswertbaren primären und sekundären Karzinoidmanifestationen eine Assoziation zwischen dem DNA-Histogrammtyp metastatischer Karzinoide und der Prognose. Innerhalb der Gruppe der Ileumtumoren erlaubte der Parameter DNA-Gehalt aber keine Verbesserung der Prognoseabschätzung.

    Description / Table of Contents: Summary Apoptosis and proliferation are important regulators of normal development and homeostasis in the bone marrow. Therefore, dynamics of hematopoiesis is mainly defined by these two parameters. However, since only few data are available from previous studies, we performed a retrospective analysis to elucidate some aspects of this complex pathomechanism. A total of 400 patients with chronic myeloproliferative disorders (CMPDs) and corresponding reactive bone marrow lesions were enrolled into this study. Apoptosis was detected in bone marrow tissue by the ISEL-technique and topoisomerase II α expression was demonstrated by the monoclonal antibody Ki-S1. Furthermore, by determination of the proliferating-cell nuclear antigen labeling (PCNA) index, we were able to calculate the proportion of cells in the G2/M phase, because both nuclear antigens are expressed in different phases of the cell cycle. Patients with IMF, PV, and ET revealed a normal range of apoptosis, whereas in chronic myeloid leukemia (CML) a significant increase could be observed. On the other hand, IMF and PV were characterized by a raised proliferative activity. Dynamics of hematopoiesis was assessed by calculation of the so called hematopoietic turnover index. In CML and reactive lesions no alterations of this parameter were detectable, but IMF and PV showed a significant increase. Survival analysis disclosed a relevant worsening of life expectancy for patients with reduced apoptosis and proliferation. In conclusion, our in-situ results confirm and extend previous experimental data on hematopoietic cell kinetics. In this context, a greater regenerative capacity of hematopoiesis may be reflected by an increased rate of apoptosis and/or proliferation and therefore is associated with a more favorable outcome.
    Notes: Zusammenfassung Apoptose und Proliferation stellen im Rahmen einer funktionsgerechten Regelung der Hämatopoese einen integralen Bestandteil für die Aufrechterhaltung des zellulären Gleichgewichts im Knochenmark dar. Insofern ist die Dynamik des hämatopoetischen Zellumsatzes durch diese beiden Parameter gekennzeichnet. Da weiterführende Untersuchungen in dieser Hinsicht lediglich vereinzelt am Knochenmark durchgeführt worden sind, haben wir im Rahmen einer retrospektiven Analyse versucht, einige Aspekte dieses komplexen Mechanismus zu beleuchten. Insgesamt wurden 400 Patienten mit chronischen myeloproliferativen Erkrankungen (CMPE) sowie korrespondierenden reaktiven Veränderungen in die Untersuchung aufgenommen. Neben dem direkten Nachweis der Apoptose im Knochenmark durch die ISEL-Technik haben wir die Topoisomerase II α Expression mittels des monoklonalen Antikörpers Ki-S1 gemessen. Zusätzlich konnten wir durch die Bestimmung der PCNA-Markierung aufgrund der Zellzyklus-spezifischen Färbereaktion beider nukleärer Antigene den Anteil der in G2-/M-Phase befindlichen Zellen ermitteln. Während die IMF, die PV sowie die ET eine im Normbereich liegende Apoptoserate erkennen ließen, war dieser Wert bei der CML signifikant erhöht. Auf der anderen Seite wiesen IMF und PV eine deutlich gesteigerte proliferative Aktivität im Knochenmark auf. Bei der Berechnung eines hämatopoetischen Zellumsatz Index (HZI) zeigten diese beiden CMPE-Subtypen einen signifikanten Anstieg, wohingegen bei der CML sowie den reaktiven Läsionen keine relevante Verschiebung dieses Parameters festzustellen war. Im Rahmen prognostischer Analysen hatten IMF und PV Patienten mit reduzierter Proliferation und Apoptoserate jeweils eine signifikant kürzere Überlebenszeit. Unsere in-situ Ergebnisse erweitern und bestätigen vorausgegangene experimentelle Studien zur hämatopoetischen Zellkinetik. Darüber hinaus lassen sich aus unseren Daten prognostische Überlegungen ableiten, da insbesondere bei der PV und IMF Apoptose und Proliferation signifikanten Einfluß auf das Überleben der Patienten hatten. In diesem Zusammenhang spiegelt eine vermehrte Apoptose- und Proliferationsrate im Knochenmark offenbar eine größere regenerative Kapazität der Hämatopoese wieder und könnte daher für einen günstigeren Verlauf verantwortlich gemacht werden.

    Notes: Abstract Immunoreactivity of p21WAF1/CIP1 and cyclin D1 proteins was assessed in a cohort of 207 patients with superficial (pTa-pT1) bladder cancer followed up for a mean of 4.9 years. The results of the immunostainings were compared with T category, WHO grade, tumor cell proliferation rate (MIB-1 score), the expressions of p53 and bcl-2 as well as survival. Sixty-eight percent and 75% of the tumors were p21WAF1/CIP1 positive (≥5% of cells positive) and cyclin D1 positive (≥10% of cells positive), respectively. The p21WAF1/CIP1 expression was related to cyclin D1 immunolabelling (P 〈 0.001) but not to the other variables studied. The expression of cyclin D1 was inversely associated with T category (P=0.001), WHO grade (P=0.006), MIB-1 score (P=0.014), p53 expression (P=0.001), and bcl-2 (P=0.011) immunoreactivity. In univariate analysis, T category (P=0.0001), WHO grade (P 〈 0.0001), MIB-1 score (P 〈 0.0001), bcl-2 (P=0.0092), p53 (P=0.0016) and p21WAF1/CIP1 (P=0.009) expressions were significant prognostic factors with regard to tumor progression, whereas cyclin D1 was without any prognostic significance (P=0.1). Out of 123 p21 positive tumors 21 progressed, whereas only 2 out of 58 p21 negative tumors progressed. In multivariate analysis, the MIB-1 score was the only independent predictor of cancer-specific survival (P=0.03), whereas tumor grade (P=0.002) and cyclin D1 expression (P=0.04) were independent predictors of tumor recurrence. Only the WHO grade (P=0.04) retained its prognostic value indicating the risk of progression. We suggest that in superficial bladder cancer p21WAF1/CIP1 and cyclin D1 immunohistochemistry provide no additional prognostic information compared with already established prognostic factors for predicting the risk of progressive disease.

    Description / Table of Contents: Abstract In individual patients with head and neck squamous cell carcinomas (HNSCC), established prognostic factors do not satisfactorily predict clinical outcome. For the first time we investigated a total of 100 HNSCC by Comparative Genomic Hybridization (CGH) to define chromosomal alterations that are associated with the patients prognosis. Patients were followed for at latest 4 but at least 2 years after surgery or until death. During this observation period twenty-nine of them died because of cancer disease. The Kaplan-Meier method was used plotting survival curves for every single chromosomal alteration as well as every clinico-pathological parameter. The curves were tested for significance by the log rank as well as the Breslow test. Significance of particular prognostic parameters was then evaluated by the Cox regression model. The overall survival time as well as the recurrence free survival time were significantly lower in patients who's tumors showed amplifications of the chromosomal region 11q13 (p=0.0008 for LR and p=0.0024 for B). The survival time of the patients was also lower if the carcinomas carried overrepresentations of chromosome 3q (p=0.0299 for LR and p=0.0546 for B). Multivariate analysis (Cox's proportional hazards model) revealed both alterations as most important independent prognostic factors in HNSCC. None of the conventional clinico-pathological parameters (pT-, pN-status, UICC stage, grading) achieved statistical significance in the multivariate model. These results suggest that in HNSCC the occurence of 11q13 amplification and 3q overrepresentation are highly significant independent prognostic markers and of better value than the established TNM and grading criteria.
    Notes: Zusammenfassung Die Prognose von Patienten mit Kopf-Hals-Karzinomen lässt sich anhand der etablierten Stagingparameter oft nur sehr ungenügend einschätzen. Auf der Suche nach neuen Markern, die den Tumorphänotyp genauer charakterisieren, wurden in der vorliegenden Studie 100 primäre Plattenepithelkarzinome des Kopf-Hals-Bereichs mit Hilfe der Comparativen Genomischen Hybridisierung (CGH) molekularzytogenetisch untersucht. Die detektierten genetischen Veränderungen (Deletionen oder DNA-Überrepräsentierungen bzw. Amplifikationen) wurden für jeden Chromosomarm aufgeschlüsselt und statistisch zusammen mit den klinisch-pathologischen Daten uni- und multivariat hinsichtlich ihrer prognostischen Aussagefähigkeit überprüft. Alle Patienten dieser Studie wurden primär operiert und in Abhängigkeit vom Tumorstadium adjuvant nachbestrahlt. In dem längstens 4-jährigen Beobachtungszeitraum waren von den 100 Patienten 29 am Tumorleiden verstorben. Die kumulierten Überlebensraten nach der Kaplan-Meier-Methode zeigten, dass sowohl die rezidiv- und metastasenfreie als auch die Gesamtüberlebenszeit signifikant kürzer ist bei Patienten, deren Tumoren eine Amplifikation der chromosomalen Region 11q13 und/oder eine DNA-Überrepräsentierung des Chromsomarms 3q aufweisen (p=0,0008 bzw. p=0,0299 im Log-Rank-Test und p=0,0024 bzw. p=0,0546 im Breslow-Test). Die Cox-Regression wurde für das rezidiv- und metastasenfreie Überleben und für das Gesamtüberleben jeweils mit den klinisch-pathologischen Parametern pT-, pN-Status, UICC-Stadium, Grading und den genetischen Markern 11q13-Amplifikation sowie 3q-Überrepräsentierung durchgeführt. Die Analyse ergab die genetischen Veränderungen im Bereich von 11q13 und 3q als die wichtigsten Marker für die Einschätzung des Überlebens, während die klinisch-pathologische Tumorklassifikation ohne prognostischen Einfluss war (bei Signifikanzniveau p〈0,05). Das Ergebnis unserer Studie eröffnet die Möglichkeit eines “genetischen Tumorgradings”, das als Zusatzinformation einer verbesserten Prognoseeinschätzung bei Kopf-Hals-Karzinomen dient.

    Description / Table of Contents: Abstract. Aim: To determine clinical and physiologic parameters enabling the prognosis of continence after protective ileostomy closure secondary to rectal resection for rectal cancer. Method: Patients who had undergone rectal resection (n = 65, of whom 24 had had radiochemotherapy) were evaluated by clinical examination, anorectal manometry and orthograde contrast enema before ileostomy closure. Continence was evaluated by clinical findings 91 ± 52 weeks after stoma closure with the help of standardized questionaires and classified according to the Wexner continence score. The relationship between findings before stoma closure and continence score was calculated with Pearson's correlation coefficient. Results: Correlations were found to be significant between the continence score and the level of anastomosis (r = –0.58, p 〈 0.001), median resting pressure (r = –0.52, p 〈 0.001), rectal compliance (r = –0.43, p 〈 0.001). Additionally, radiochemotherapy impairs continence (p = 0.0001). Correlations were not significant between continence and functional sphincter length, squeeze pressure, threshold for perception, urge and maximal tolerable volume, and continence for semiliquid contrast medium. Conclusion: Incontinence after rectum resection is multifactorial: the level of anastomosis, resting pressure, rectal compliance and radiochemotherapy all play a dominant role. Based on these findings, the continence score can be calculated before closure of a diverting ileostomy by applying multivariate analysis with the help of the following formula: Continence score = 18.23–0.94 · level of anastomosis – 0.18 · resting pressure + 3.72 · radiochemotherapy.
    Notes: Zusammenfassung. Ziel dieser Studie war eine Evaluation von klinischen und physiologischen Parametern zur Vorhersage des Kontinenzgrades nach Rückverlagerung der protektiven Loop-Ileostomie nach Rectumresektion wegen eines Carcinoms. Methode: 65 Patienten wurden klinisch mittels anorectaler Manometrie und orthograder Röntgenkontrastmitteldarstellung vor der Ileostomieresektion untersucht. Bei 24 Patienten war eine Radiochemotherapie durchgeführt worden. Der klinische Status wurden 91 ± 52 Wochen nach der Ileostomieresektion mittels eines standardisierten Fragebogens erhoben und der Kontinenzgrad nach dem Wexner-Kontinenzscore bewertet. Der postoperative Kontinenzscore wurde mit den Befunden vor Stomarückverlagerung korreliert und ein Pearson-Korrelationskoeffizient berechnet. Ergebnisse: Es ergab sich eine signifikante Korrelation des Kontinenzgrades mit der Anastomosenhöhe (r = –0,58, p 〈 0,001), dem mittleren Ruhedruck (r = –0,52, p 〈 0,001) und der rectalen Compliance (r = –0,43, p = 0,001). Die Kontinenz war nach Radiochemotherapie schlechter (p = 0,0001). Es fand sich keine signifikante Korrelation zwischen Kontinenzgrad und funktioneller Sphincterlänge, Kneifdruck, Perceptionsschwelle, Drangschwelle, maximal tolerablem Volumen und Kontinenz für semiliquides Kontrastmittel. Schlußfolgerung: Inkontinenz nach Rectumresektion ist multifaktoriell. Anastomosenhöhe, mittlerer Ruhedruck, rectale Compliance und Radiochemotherapie (RCT) spielen eine dominante Rolle. Basierend auf diesen Befunden ist über die Berechnung einer multivariaten Regressionsanalyse eine Abschätzung des Kontinenzgrades vor Ileostomieresektion mit folgender Formel möglich: Prognose-Wexner-Score = 18,23–0,94 · Anastomosenhöhe – 0,18 · Ruhedruck + 3,72 · RCT.

In addition to conventional MRI diagnostics for the detection of small epileptogenic lesions, proton magnetic resonance spectroscopic imaging (HMR spectroscopy) can be useful for assessing the bilaterality of pathological changes in cryptogenic temporal lobe epilepsies. The technique and findings of HMR spectroscopy are reported in patients with cryptogenic temporal lobe epilepsies. The findings indicate that chemical shift imaging (CSI) investigations of the ipsilateral and contralateral hemispheres provide important information for the prediction of seizure outcome after epilepsy surgery.
    Notes: Zusammenfassung Bei der epilepsiechirurgischen Behandlung kryptogener Temporallappenepilepsien kommt neben der Lokalisation des epileptischen Fokus der Beurteilung der Prognose hinsichtlich der postoperativen Anfallskontrolle Bedeutung zu. Hierbei kann die Protonen-MR-Spektroskopie (1 HMR-Spekroskopie oder Chemical Shift Imaging CSI) nützliche Informationen liefern. Technik und Befunde des CSI im Vergleich zu einem Normkollektiv werden bei Patienten mit kryptogenen Temporallapenepilepsien dargestellt. Hierbei werden Ergebnisse der 1HMR-Spekroskopie (NAA/Cholin) und der T2-Relaxometrie mit der postoperativen Anfallskontrolle verglichen. Die Ergebnisse zeigen, dass die 1HMR-Spekroskopie mit NAA/Cholin wichtige Informationen für die Prädiktion hinsichtlich der postoperativen Anfallskontrolle liefert.

    Notes: Abstract Increased expression of argyrophilic nucleolar organizer regions (AgNORs) has been identified in certain malignant tumors including nasopharyngeal carcinoma (NPC). However, its prognostic significance in NPC is uncertain and remains to be evaluated. To address this we silver-stained 63 paraffin sections of NPC cases, and examined the correlation between AgNOR count and area, calculated by the CAS 200 image analysis system, and tumor behavior, locoregional control, and survival of patients. The mean AgNOR count and area were 1.62 ± 0.31 and 3.98 ± 11.4 μm2, respectively. The AgNOR area was positively associated with T stage (r = 0.26, P = 0.04). The Mann-Whitney test confirmed no significant difference in AgNOR area and count between patients with different outcomes. Multivariate analysis using the Cox proportional hazard model showed neither AgNOR count nor area to be significant predictors of actuarial survival or disease-free survival. It is concluded that AgNOR does not have an independent and significant prognostic value in NPC. AgNOR expression may be merely a reflection of malignant phenotype as well as cellular activity but not necessarily the ultimate behavior of the tumor.

    Description / Table of Contents: Summary Background: The outcome of 20 patients is summarized in a retrospective study to identify clinical findings that influence the long-term prognosis of postoperative endophthalmitis. Patients: Between 1991 and 1997 a total of 20 patients with postoperative endophthalmitis were admitted. Median age was 80 years (range: 9–95), 11 patients were male, 9 female. Sixteen pars-plana vitrectomies, 2 anterior vitrectomies and 2 rinsings of the anterior chamber without vitrectomy were performed. Furthermore, all patients received intraocular and systemic antibiotic treatment. For microbiological investigation, specimens from vitreous, anterior chamber and conjunctiva were sent in. Long-term outcome was controlled for an average of 14 months after treatment of the endophthalmitis (range: 4–36 months). Results: At the end of treatment, 40% of patients had a visual acuity of 0.4 or better, 80% had 1/20 or better. Patients with a preoperative visual acuity of at least hand movement had a better postoperative visual outcome than patients with only light perception. Visual acuity was better in patients with chronic endophthalmitis than in patients with acute or subacute endophthalmitis. In patients with chronic or subacute endophthalmitis, improvement of visual acuity was found some months after the operation more often than in patients with acute endophthalmitis. However, in 40% of cases with an acute onset, no improvement or even worsening of the visual acuity was documented. Best postoperative results were found after infection with Staphylococcus epidermidis and Propionibacterium acnes. Conclusion: Important prognostic factors of postoperative endophthalmitis are visual acuity, the onset of the endophthalmitis (acute, subacute or chronic) and the microbiological findings. At the time of surgery and antibiotic treatment, visual acuity should be at least hand motion to expect an improvement in the visual outcome.
    Notes: Zusammenfassung Fragestellung: Im Rahmen einer retrospektiven Studie sollte das Patientengut mit postoperativer Endophthalmitis bezüglich prognostischer Gesichtspunkte ausgewertet werden. Patienten und Methode: 20 Patienten (9 weiblich, 11 männlich), im Alter von 9–95 Jahren (Median 80 Jahre) mit postoperativer Endophthalmitis wurden im Zeitraum von 1991 bis 1997 in unserer Klinik behandelt. 16mal wurde eine Pars-plana-Vitrektomie (PpV) durchgeführt, weiterhin 2 vordere Vitrektomien und 2 Vorderkammerspülungen ohne Vitrektomie. Alle Patienten erhielten intraokular und systemisch Antibiotika. Der postoperative Beobachtungszeitraum betrug 4 bis 36 Monate (im Durchschnitt 14,0). Die mikrobiologische Untersuchung umfaßte Kulturen von Glaskörper, Vorderkammer und Bindehaut. Ergebnisse: Bei 80% der Patienten war der letzte Visus 1/20 und besser, bei 40% mindestens 0,4. Bei einem präoperativen Visus von mindestens Handbewegung (HB) war der postoperative Visus besser als bei einem schlechteren Ausgangsvisus (Lichtschein). Die chronischen Endophthalmitiden hatten ein besseres Visusergebnis als die akuten und subakuten Endophthalmitiden. Bei den chronischen und subakuten Verläufen war häufiger als bei den akuten Verläufen noch ein Visusanstieg in den ersten Monaten nach der Operation möglich. Bei 40% der akuten Verläufe stagnierte der Visusanstieg, oder der Visus wurde schlechter. Der postoperative Visus war bei Staphylococcus epidermidis- und Propionibacterium acnes-Infektionen am besten. Schlußfolgerung: Prognostische Faktoren der postoperativen Endophthalmitis sind der Visus, das Kulturergebnis und die Verlaufsform (akut, subakut, chronisch). Zum Zeitpunkt der Operation und der intravitrealen Antibiotikagabe sollte der Visus nicht schlechter als Handbewegungen sein, um postoperativ einen besseren Visus zu erreichen.

    Notes: Abstract Basaloid squamous cell carcinoma (BSC) is regarded as a variant of squamous cell carcinoma, but displays distinct morphological and biological features as well as a different clinical course. The tumor is frequently seen in the head and neck and is preferentially located in the larynx, especially in supraglottic sites. Ten patients with BSC of the supraglottic larynx were treated from 1991 to 1995 at the Medical Faculty of the University of Istanbul. Results of treatment were compared retrospectively with a control group consisting of 44 patients with well-differentiated squamous cell carcinomas. Ages, ¶localizations, stages and treatment procedures were similar. In both groups mean survival, nodal involvement and distant metastases were comparable although the local ¶(laryngeal) recurrence rate in patients with early supraglottic (T2) disease in the BSC group after conservative partial surgery was distinct compared to the control group (P 〈 0.05). These results indicate that conservative surgery should be assessed with caution in patients with BSC, and postoperative irradiation be taken into consideration.

    Notes: Abstract  Tumour progression is characterised by an imbalance between cell proliferation and apoptosis. The aim of our study was to estimate the importance of proliferation and apoptosis associated parameters in primary squamous cell carcinomas (SCCs) of the oral cavity and oropharynx. For determination of apoptosis, the enzymatic labelling of DNA fragmentation with a terminal transferase reaction was used in 156 tissue samples of 107 patients, including corresponding lymph-node metastases in nine cases. P53, bcl-2, and Ki-67 were determined immunohistologically. P53 was detectable in 50.5% of the cases. Positive staining was associated significantly with decreased apoptosis (P〈0.003). Bcl-2 was upregulated in 31.8% of the cases depending on the tumour grading (P〈0.001) and correlated negatively with apoptosis (P〈0.001). Proliferation (P〈0.006) and apoptosis (P〈0.03) were enhanced in larger tumours, though a direct correlation between these two parameters was not proven. Nevertheless, in contrast to the conventional tumour staging and grading, neither the expression of p53 or bcl-2 nor the apoptosis or Ki-67 measurements were able to predict survival or recurrence-free survival of the patients suffering from a SCC in the oral cavity or oropharynx. Our observations suggest that the function of wild-type p53 to induce apoptosis is lost in at least half of the SCCs under study and that the physiological function of bcl-2 as potent inhibitor of apoptosis is widely preserved in oral SCC.

    Notes: Abstract  Prediction of evolution of secondary hyperplasia and tumours of the parathyroid glands is still a problem in histopathology. To assess whether the quantity of silver-stained nucleolar organiser region (AgNOR) proteins might be used as a prognostic tool in parathyroid pathology, a standardised AgNOR analysis has been performed on 19 cases of parathyroid hyperplasia caused by secondary hyperparathyroidism (PH), 8 cases of adenoma (PA) and 10 cases of carcinoma (PC). Clinico-pathological data and follow-up information were available. On formalin-fixed and paraffin-embedded sections, the visualisation and quantification of AgNORs were achieved according to the 1995 guidelines of the Committee on AgNOR Quantification. Then, the mean area (square micrometres) of AgNORs per nucleus (NORA) was evaluated by means of an image analyser and specific softwares. After testing the normal distribution of NORA values, statistical parametric tests were utilised; Kaplan-Meier and Cox multivariate analyses were also performed. In parathyroid lesions, a progressive increase of mean NORA values was observed from PH (2.895 µm2; SE 0.171) through PA (3.638 µm2; SE 0.125) to PC (4.701 µm2; SE 0.179); these differences were highly significant (P〈0.001), although some degree of overlap was found among single NORA values. A significantly higher mean NORA value was revealed in PC with distant metastases than was noted in cases with no current clinical evidence of disease progression. Furthermore, a significantly (P〈0.001) higher mean NORA value was encountered in the group of PH with recurrences (3.600 µm2; SE 0.106) than in nonrecurrent PH (2.261 µm2; SE 0.087). Multivariate analyses indicated that the NORA value was an independent prognostic parameter determining the risk of recurrence in PH. We suggest that AgNOR quantity may be a promising additional tool for predicting the biological behaviour of parathyroid lesions.

    Notes: Abstract  Lectins are proteins and glycoproteins of non-immune origin which bind specifically to carbohydrate residues, agglutinate cells and/or precipitate complex carbohydrates. Lectin-binding patterns in normal, hyperplastic and neoplastic endometria were studied using four biotinylated lectins (Con A, LCA, e-PHA, l-PHA) and the avidin-biotin-peroxidase technique. Canavalia ensiformis agglutinin (ConA) and Lens culinaris agglutinin (LCA) reacted strongly with the luminal borders and the cytoplasm of epithelial cells but, whilst in normal and benign endometrial tissues the cytoplasmic staining was confined to the apical and the basal aspect of the cells, in endometrial carcinomas and in some atypical hyperplasias lectin binding also occurred in the lateral cytoplasm (Con-A-lat), although in differing proportions of cells. Interestingly, extensive Con-A-lat in the tumour cells was much more frequent in non-endometrioid carcinomas (P〈0.05) and was significantly associated with poor histological differentiation (P〈0.0001), low oestrogen and progesterone receptor content (P〈0.01 and P=0.0001, respectively) and an unfavourable long-term survival (P〈0.05). With Phaseolus vulgaris erythroagglutinin (e-PHA) and leucoagglutinin (l-PHA) a linear, rather inconsistent, staining at the level of the basement membranes was observed in the glands: this, also noted with LCA, appeared intact in normal and hyperplastic glands without cytological atypia, and fragmented or absent in malignant glandular structures and in most hyperplastic glands showing cytological atypia. It is concluded that changes in the distribution of lectin-binding molecules in the endometrial cells are associated with the malignant state, whilst the extent of Con-A-lat reflects the biological behaviour of the tumours.

    Notes: Abstract  Recent studies have shown that expression of alternatively splicing variants of CD44 is correlated with prognosis for several kinds of malignant tumors. However, little is known about the expression of CD44 standard and variant isoforms in soft tissue sarcomas. In this study 47 cases of soft tissue sarcoma [18 malignant fibrous histiocytomas (MFHs), 13 synovial sarcomas (SSs), 7 malignant schwannomas (MSs), and 9 liposarcomas (LSs)] were examined immunohistochemically. The monoclonal antibodies to the standard form of CD44 (CD44H) and variant exons of CD44v3, 4, 5, 6, 7, 9, and v10 were used. We analyzed the membranous expression pattern of CD44H and CD44 variant exons and assessed the relation between expression of CD44s and metastasis-free survival rates (MFSR) of patients with soft tissue sarcoma. A few sarcomas expressed CD44v3 (2/47) and v7 (2/47), but none of the sarcomas expressed CD44v10. CD44v4 (5/47), v5 (4/47), v6 (10/47), and v9 (9/47) are relatively common types of variant isoforms in soft tissue sarcomas. Expression of CD44v6 is more frequently detected in high-grade than in low-grade tumors. CD44v6 or CD44v9 expression was correlated with metastasis-free survival of patients with soft tissue sarcomas.

    Notes: Abstract We encountered a patient with acute myelogenous leukemia (AML) who developed leukemic hypopyon. Leukemia initially spread into the pharynx, gingiva, lymphnode, and bone marrow. He achieved complete remission after chemotherapy but developed blurred vision and hypopyon. Anterior chamber paracentesis disclosed leukemic infiltration of the anterior chamber. Infiltration of the central nervous system also occurred. He received systemic chemotherapy, intrathecal chemotherapy, and local chemotherapy. However, he did not achieve prolonged remission. These findings suggest that these chemotherapy treatments have an inadequate effect for AML with anterior chamber infiltration. This rare complication is associated with extramedullary infiltration of leukemia.

    Notes: Abstract Of 50 patients with pT3b, pT4 and/or pN+ disease after cystectomy, 27 were administered adjuvant four cycles of cisplatin, methotrexate and vinblastine (CMV) and 23 were followed expectantly (no-treatment group).Median follow-up was 14 months in CMV group and 11 months in no-treatment group. Median recurrence-free survival was 21 months in CMV group and 17 months in no-treatment group (p = 0.573). Median overallsurvival was 41+ months in CMV group and 84+ months in no-treatmentgroup, respectively (p = 0.501). In our experience, adjuvant chemotherapy after cystectomy seemed not to provide a survival advantage.

    Notes: Abstract PURPOSE: Magnetic resonance imaging of fistula-in-ano has been shown to predict surgical anatomy accurately and identify complex features. In addition, fistula complexity has been correlated with poor outcome after surgical intervention. We investigated whether preoperative magnetic resonance imaging could predict clinical outcome after surgery for fistulous disease better than clinical examination under anesthetic. METHODS: Seventy patients with clinically suspected fistula-in-ano underwent preoperative dynamic contrast-enhanced magnetic resonance imaging before surgical exploration. Outcome was assessed at a minimum of one year after surgical exploration and correlated in a blinded fashion with the surgical and magnetic resonance grading of the severity of the fistulous disease. RESULTS: Of 70 patients, 12 were not operated on and 6 were lost to follow-up, making 52 patients eligible for analysis. Assessment by dynamic contrast-enhanced magnetic resonance imaging more accurately predicted outcome than the findings at initial surgical exploration. Dynamic contrast-enhanced magnetic resonance imaging had a sensitivity of 81 percent, specificity of 73 percent, and positive predictive value of 75 percent; surgery had a sensitivity of 77 percent, specificity of 46 percent, and positive predictive value of 59 percent. Surgical assessment of apparent disease severity bore no relation to final outcome. Dynamic contrast-enhanced magnetic resonance imaging could accurately predict whether patients were likely to have a satisfactory or unsatisfactory outcome after surgery. CONCLUSION: Dynamic contrast-enhanced magnetic resonance imaging better predicts clinical outcome of patients with fistula-in-ano than initial surgical exploration.

    Notes: Abstract PURPOSE: Colorectal adenocarcinoma before the age of 40 is uncommon, and its prognosis is controversial, with many studies reporting a worse prognosis than in older patients and others showing no difference. The current study compared two groups of patients who had surgical resection for colorectal adenocarcinoma. METHODS: The case group was composed of 34 patients younger than 40 (34 ± 4) years. Detailed pathologic prognosis factors, tumor cell proliferation measured by proliferating cell nuclear antigen, survival, family history, and predisposing conditions were analyzed. Results were compared with a control group constituted of 34 patients older than 65 (75 ± 6) years matched by gender, cancer site, and Dukes stage. RESULTS: Tumor differentiation, presence of vascular and perineural neoplastic invasion, tumor growth pattern, tumor cell proliferation measured by proliferating cell nuclear antigen count, and survival according to the Kaplan-Meier method were not significantly different between younger and older patients. The only difference between the two groups was a higher prevalence of family history and predisposing conditions for colorectal cancer in younger patients (23vs. 3 percent;P=0.03). CONCLUSION: This case-control study documents that pathologic features and prognosis of colorectal adenocarcinoma are comparable in patients younger than 40 years compared with older patients for identical stages. The higher prevalence of positive family history in younger patients suggests a different genetic background compared with older patients.

    Notes: Summary Background: The diagnostic value of admission serum levels of procalcitonin (PCT) and C-reactive protein (CRP) as indicators of the etiology and prognosis was prospectively investigated. Patients: 96 patients, 50–85 years of age, treated in the hospital for community-acquired pneumonia (CAP). Results: On admission, all patients had elevated CRP levels (〉 10 mg/l), but only 60 patients (54%) had elevated PCT levels (〉 0.1 μg/l). The severity of disease measured by APACHE II score was strongly associated with admission levels of PCT (p = 0.006), but not with CRP. Eight of nine patients with pneumonia caused by atypical agents had PCT levels 〈 0.5 μg/l compared with 6/27 patients with pneumonia caused by classical bacterial pathogens, mainly Streptococcus pneumoniae (p = 0.03). No such correlation between CRP levels and etiology was found. Conclusion: Our data indicate that in patients admitted to the hospital with CAP, measurement of PCT gives information about the severity of the disease, and may aid the physician to differentiate typical bacterial etiology from atypical etiology, and thereby to choose appropriate initial antibiotic treatment.

    Description / Table of Contents: Hintergrund: Wir haben in einer retrospektiven Analyse die Häufigkeit eines Herpes zoster bei Patientinnen mit Mammakarzinom und postoperativer Radiotherapie untersucht. Patientinnen und Methode: Von Januar 1985 bis Dezember 1993 erhielten 1 155 Patientinnen an unserer Klinik eine postoperative Bestrahlung nach Mastektomie (n = 961) oder brusterhaltende Operation (n = 194) in kurativer Intention. Das Alter betrug 34 bis 79 Jahre. 443 (38%) waren prä- und 712 (62%) postmenopausal, 21% hatten T3- bis T4-Tumoren, und 55% wiesen einen axillären Lymphknotenbefall auf. Alle Patientinnen erhielten eine Bestrahlung der Restbrust bzw. Thoraxwand bis 50 Gy, bei mastektomierten Patientinnen wurden zusätzlich die regionären Lymphknoten mit 44 Gy bestrahlt. 65% der Patientinnen erhielten eine zusätzliche Systemtherapie. Die Nachbeobachtungszeit betrug drei Monate bis 12,5 Jahre (Median 3,1 Jahre). Ergebnisse: 41/1 155 Patientinnen (3,7%) entwickelten im Nachbeobachtungszeitraum einen Herpes zoster. Alle Infektionen waren lokalisiert, eine generalisierte Hautinfektion oder systemische Infektionen traten nicht auf. Alter, Menopausenstatus, Erkrankungsstadium oder Art der Therapie (Brusterhaltung vs. Mastektomie, zusätzliche Chemotherapie) hatten keinen Einfluss auf die Frequenz von Zoster. Patientinnen mit starker akuter Hautreaktion waren ebenfalls nicht signifikant stärker betroffen als Patientinnen mit geringer Hautreaktion im Bestrahlungsfeld (5% vs. 2%). Das Auftreten eines Zosters nach Therapie hatte keinen Einfluss auf die Prognose hinsichtlich lokaler Kontrolle oder Überleben. Schlussfolgerungen: Die beobachtete Häufigkeit von Herpes zoster (etwa 4% nach drei Jahren Follow-up) lässt vermuten, dass ein Herpes zoster im untersuchten Kollektiv etwa drei- bis fünffach häufiger auftritt als anhand der Inzidenzen in der Normalbevölkerung erwartet. Dies ist nicht mit einer schlechteren Prognose assoziiert. Ob die erhöhte Frequenz auf die Radiotherapie zurückzuführen ist oder in Zusammenhang mit der Krebserkrankung steht, kann nich beurteilt werden.
    Notes: Background: We have studied the incidence of herpes zoster in patients with adjuvant radiotherapy for breast cancer with special emphasis on possible correlations with other prognostic factors or survival. Patients and Methods: From 1/1985 through 12/1993, 1 155 breast cancer patients received postoperative radiotherapy with curative interent in our department. After mastectomy 961 patients were irradiated and after breast-preserving treatment 194 patients. The age ranged from 34 to 79 years, the median follow-up was 3.1 years (range: 0.3 to 12.4 years). There were 443 women (38%) pre- and 712 (62%) postmenopausal. 21% had T3- to T4-tumors, 55% had axillary lymph node involvement, and 65% received additional systemic hormonal and/or cytotoxic therapy. In case of postmastectomy radiotherapy, the lateral chest wall and lymphatics (axilla, parasternal and supraclavicular nodes) were irradiated with an anterior photon field to 50 Gy (axilla 44 Gy) and most of the chest wall with an electron field to 44 Gy in 2-Gy fractions. After breast-preservation, the breast was irradiated via tangential fields with 6- to 8-MV photons up to 50 Gy plus 8 Gy electron boost to the tumor bed. Most of the patients were followed routinely in the department for 2 to 5 years. The frequency of zoster was determined retrospectively by reviewing the patients' records. Results: A zoster after radiotherapy occurred in 41/1 155 patients (3.7%), mostly within the first 2 years after completion of radiotherapy. All infections remained localized and there was no evidence for systemic infections. Type of treatment (mastectomy vs breast-preservation) had no impact on the frequency of herpes zoster (36/961 patients after mastectomy and 5/194 patients after breast-preservation). There was also no correlation with other prognostic factors such as age, menopausal status, stage of disease or the use of adjuvant chemotherapy, nor was the occurrence of zoster linked to the degree of acute skin reaction in the radiation field. Moreover, patients with zoster had the same prognosis as compared to patients without zoster with regard to local control and survival. Conclusions: The observed frequency of zoster (about 4% of patients after postoperative radiotherapy) in this retrospective study suggests that the risk of developing zoster in this patient group may be 3- to 5-fold higher as compared to the incidence in the general population. However, the occurrence of zoster was not linked to prognosis and treatment response.

    Description / Table of Contents: Abstract The treatment of injuries to the PCL is still controversial. There are still no answers to many questions on the biomechanics of PCL, the natural history of PCL injury, the surgical technique of PCL reconstruction and the biology of PCL healing. It is well established that primary repair of bony avulsions of the PCL provides good static and functional results. PCL tears should also be treated surgically in combined knee ligament injuries. For isolated midsubstance tears of the PCL, however, no prospective randomised long-term studies are available to date demonstrating that surgical treatment with current techniques leads to better results than nonoperative, functional treatment. Nonoperative management is advocated because the knee instability following isolated PCL midsubstance tear is only moderate, the natural history has been seen to end in acceptable functional stability, knee proprioception is preserved, and the incidence of late osteoarthritis is low.
    Notes: Zusammenfassung Die Behandlung von Rupturen des hinteren Kreuzbands wird international noch immer kontrovers diskutiert. Zahlreiche Fragen zur funktionellen Anatomie, zum Spontanverlauf nach Ruptur, zur chirurgischen Technik sowie zum Heilungsverlauf sind unbeantwortet. Gesichert ist, daß die primäre operative Versorgung von knöchernen Ausrissen des hinteren Kreuzbands zu guten Ergebnissen führt. Bei kombinierten Knieinstabilitäten sollte das verletzte hintere Kreuzband auch operativ versorgt werden. Für die isolierte, interligamentäre Ruptur des hinteren Kreuzbands konnte bisher jedoch mit keiner prospektiven, randomisierten Langzeitstudie bewiesen werden, daß die heutigen Operationsverfahren reproduzierbar zu besseren Ergebnissen führen als die konservativ-funktionelle Behandlung. Für die konservative Therapie sprechen die nur mäßige Instabilität nach isolierter Ruptur des hinteren Kreuzbands, der günstige Spontanverlauf und der Erhalt der Propriozeption des Kniegelenks sowie die im Verlauf nur geringe Arthroserate.

    Description / Table of Contents: Abstract The pathogenesis, diagnosis, treatment and prognosis of fractures of the ulna and olecranon are described. It appears that both the potential benefits of using internal fixation techniques in the proximal ulna and the olecranon and the risks involved are heavily influenced by concomitant injuries, which means that the diagnosis and appropriate treatment of these are of decisive importance for the outcome.
    Notes: Zusammenfassung Pathogenese, Diagnostik, Therapie und Prognose von Ulna- und Olekranonfrakturen werden beschrieben. Dabei zeigt sich, daß die Chancen und Gefahren bei Osteosynthesen der proximalen Ulna und des Olekranons wesentlich von den Begleitverletzungen beeinflußt werden, deren Diagnose und adäquate Behandlung demzufolge für das Outcome entscheidende Bedeutung besitzt.

    Notes: Abstract PURPOSE: The aim of this study was to evaluate the prognostic value of the apoptotic index for recurrence and disease-free survival after curative surgery for rectal cancer, particularly in relation to clinicopathologic variables, p53− and bcl-2 expression. METHODS: Formalin-fixed, paraffin-embedded tissue samples of rectal carcinomas resected curatively within a five-year period were used (N=160). Apoptotic cells with fragmented DNA were detected by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphatase-biotin nick-end-labeling method. The ratio of apoptotic tumor cells (in percent) was classified into low apoptotic index (less than 10 percent) and high apoptotic index (10 percent or more). Immunohistochemical analysis was performed using monoclonal antibodies (DO-1 for p53 and clone 124 for bcl-2). Statistics included univariate and multivariate analysis, and survival was calculated using the Kaplan-Meier method. RESULTS: Seventy-five percent of tumors showed a low apoptotic index, and 25 percent had a high apoptotic index. No correlation was found between apoptotic index and International Union Against Cancer stage (P〉0.05). However, significant correlations were documented with histologic differentiation (mean apoptotic index, 5.74 percent in moderatelyvs. 3.98 percent in poorly differentiated carcinomas; P=0.0173), lymph node involvement (mean apoptotic index, 6.11 percent in pN1vs. 3.72 percent in pN2; P=0.0074), p53 status (mean apoptotic index, 6.26 percent in p53−vs. 4.42 percent in p53+; P=0.0085), and bcl-2 expression (mean apoptotic index, 5.13 percent in bcl-2−vs. 6.51 percent in bcl-2+; P=0.0418). Tumors of the lower rectum had a lower apoptotic index than those of the upper rectum (P=0.0277). Neither univariate nor multivariate analysis assessed apoptotic index as predictor of prognosis: Recurrence rates did not differ between tumors related to apoptotic index (22 percent with low apoptotic indexvs. 15 percent with high apoptotic index; P〉0.05), and no significant differences were found regarding survival (P〉0.05). On multivariate analysis, International Union Against Cancer stage (P=0.0002), p53 (P=0.0002), gender (P=0.0136), and bcl-2 (P=0.0243) were independent predictors of recurrence. These variables, except for bcl-2, were also independently related to disease-free survival. CONCLUSIONS: Reflecting tumor biology, apoptotic index as single variable showed no prognostic significance, whereas p53 was an independent predictor for both recurrence and survival, and bcl-2 was independently related to recurrence, but not to survival. Clinically, International Union Against Cancer stage and gender were independent prognostic factors after curative surgery for rectal cancer.

    Notes: Abstract Background: The incidence of proximal gastric third carcinoma (PGC) has been rising in recent years. Classification and surgical therapy remain controversial. Methods: Between May 1986 and October 1997, 532 patients were operated for primary gastric carcinoma. All patient data were analyzed retrospectively comparing findings in patients with PGC and those with distal gastric carcinoma (DGC). Results: Two hundred fifty patients had a PGC, and 282 patients had a DGC. The rate of R0 resections was 79.3% for PGC and 81.6% for DGC. In 93.9% of the patients with PGC total gastrectomy was performed; for DGC total gastrectomy was done in 74.5% of patients. Postoperative morbidity and mortality were 29.2% for PGC and 23.8% for DGC, and 3.2% for PGC and 3.5% for DGC, respectively. Patients with advanced tumor stages (stage III and IV) were more common in the PGC group (73.3% vs. 53.6% in DGC). After R0 resection, the 5-year survival rate was 33.2% for PGC and 59.7% for DGC. Conclusions: There was no significant difference between the rates of R0 resections for PGC and DGC. Total gastrectomy can be performed with low postoperative morbidity and mortality. PGC and DGC represent the same tumor entity, and prognosis is similar, but due to more advanced tumor stages, the long-term survival is worse for patients with PGC than for those with DGC. Left retroperitoneal lymphadenectomy may be indicated for PGC.

    Notes: Abstract Background: Gastric cancer is one of the most common gastrointestinal malignancies worldwide. Some studies have suggested that it has a worse prognosis in young than in elderly patients. Methods: All young and elderly patients treated for gastric adenocarcinoma during the period 1988 to 1994 in a tertiary referral center in Mexico City were included. Demographic, clinical, and pathologic features of young patients (less than 40 years of age) with gastric cancer were compared with those of elderly patients (70 years of age or older) with the same diagnosis. Overall survival was the main outcome measure. Results: There were 38 patients in each group. The mean age of the young and elderly groups was 33 and 77 years, respectively. Family history of gastric cancer was reported by 6 patients of the younger group and by 1 patient in the older group (P 〈 .05). Most patients in both groups were symptomatic and had an advanced stage of the disease. With a mean follow-up of 17 months, the overall median survival for all patients was 12 months. By group, the median survival was 13 and 12 months for the young and elderly patients, respectively (P = .38). Variables with significant impact on survival were the stage of the disease, possibility of surgical resection, location of the tumor, and a family history of gastric cancer. Conclusions: Young patients represent a significant proportion of patients with gastric cancer in Hispanic populations. There were no significant differences in clinicopathological characteristics and outcome of gastric adenocarcinoma between young and elderly patients. Survival was determined by the stage of the tumor and the possibility of complete surgical resection.

    Notes: Abstract Background: Hepatic resection is potentially curative in selected patients with colorectal metastases. It is a widely held practice that multiple colorectal hepatic metastases are not resected, although outcome after removal of four or more metastases is not well defined. Methods: Patients with four or more colorectal hepatic metastases who submitted to resection were identified from a prospective database. Number of metastases was determined by serial sectioning of the gross specimen at the time of resection. Demographic data, tumor characteristics, complications, and survival were analyzed. Results: From August 1985 to September 1998, 155 patients with four or more metastatic tumors (range 4–20) underwent potentially curative resection by extended hepatectomy (39%), lobectomy (42%), or multiple segmental resections (19%). Operative morbidity and mortality were 26% and 1%, respectively. Actuarial 5-year survival was 23% for the entire group (median 5 32 months) and there were 12 actual 5-year survivors. On multivariate analysis, only number of hepatic tumors (P = .005) and the presence of a positive margin (P = .003) were independent predictors of poor survival. Conclusions: Hepatic resection in patients with four or more colorectal metastases can achieve long-term survival although the results are less favorable as the number of tumors increases. Number of hepatic metastases alone should not be used as a sole contraindication to resection, but it is clear that the majority of patients will not be cured after resection of multiple lesions.

    Notes: Abstract Background: Because more than 90% of local recurrences after curative surgery for rectal cancer appear within the first 36 months after surgery, an intensive and strict follow-up program during this period could improve early diagnosis and, thus, prognosis of patients. Methods: Of the 216 patients who underwent surgery for rectal cancer, 127 entered an intensive follow-up program (median follow-up: 42 months); the clinical outcome of the remaining 89 patients was reconstructed with the help of their general practitioners. Results: Fifty eight (26.8%) of the 216 patients who were treated with curative surgery alone developed a local recurrence; pelvic recurrences were prevalent. Eleven (30.5%) of the 36 patients who had recurrence during follow-up, and 6 of the 22 who had not undergone follow-up, had a reoperation with curative intent; the median survival was 19 months vs. 8 months, respectively (P 5 ns). Four (44.4%) curative reoperations were performed on the 9 asymptomatic patients and in 13 (26.5%) of the 49 cases with symptomatic local recurrences. Median survival was 15 months vs. 14 months, respectively (P 5 n.s). All patients except one (living after 42 months from reoperation) died within 48 months. Conclusions: In our study, adherence to a strict follow-up program unfortunately proved to be ineffective for improving long-term survival for patients who underwent reoperation with curative intent.

    Notes: Abstract PURPOSE: Although laparoscopic colorectal surgery is attracting ever more attention, its use for curative treatment of colorectal carcinoma in particular continues to be controversial. The present study was an attempt to analyze the results of the perioperative course, oncologic quality, and preliminary long-term results. METHOD: The data considered here were collected within the framework of a prospective, observational study initiated on August 1, 1995, and involving a total of 18 institutions in Germany and Austria. At the end of three years, the results are now being presented selectively,i.e., focusing only on abdominoperineal resection. RESULTS: A total of 116 patients underwent laparoscopic abdominoperineal resections, 98 (84.5 percent) of which were performed with curative intent. The mean operating time was 226 (confidence interval, 140–365) minutes. Seven patients (6 percent) experienced an intraoperative complication, which in more than one-half of the cases was a vascular injury involving the presacral venous plexus; the conversion rate was 3.4 percent. Postoperatively, 40 patients developed 97 complications—including those of a very minor nature—giving an overall morbidity rate of 34.4 percent. Reoperation in six patients (5.2 percent) had to be performed for an afterbleed in one-half of the cases and ileus in the other one-half. Postoperative mortality was a low 1.7 percent. In most of the curative resections, an oncologically radical operation with high transection of the inferior mesenteric artery and a complete dissection of the pelvis down to the floor was performed. The median number of lymph nodes investigated was 11.5, and there was wide fluctuation in the numbers among the individual institutions. Tumor cell dissemination occurred intraoperatively in five patients. In the meantime, 79 patients (81 percent) underwent at least one follow-up examination, the mean follow-up period being 491 days. Seven patients developed a local recurrence, and a further six patients developed distant metastases. For recurrence-free survival rate, the Kaplan-Meier estimation calculated a probability of 71 percent. CONCLUSION: Not all of the reservations about laparoscopic abdominoperineal resection, in particular with regard to resection with curative intent, have yet been eliminated. The present study does, however, show that a laparoscopic approach can in principle meet oncologic requirements of radicality and, with regard to the postoperative course, is associated with considerable benefits to the patient.

    Notes: Abstract PURPOSE: We evaluated the incidence and prognostic relevance of microscopic intraperitoneal tumor cell dissemination of colon cancer in comparison with dissemination of gastric cancer as a rational for additive intraperitoneal therapy. METHODS: Peritoneal washouts of 90 patients with colon and 111 patients with gastric cancer were investigated prospectively. Sixty patients with benign diseases and 8 patients with histologically proven gross visible peritoneal carcinomatosis served as controls. Intraoperatively, 100 ml of warm NaCl 0.9 percent were instilled and 20 ml were reaspirated. In all patients hematoxylin and eosin staining (conventional cytology) was performed. Additionally, in 36 patients with colon cancer and 47 patients with gastric cancer, immunostaining with the HEA-125 antibody (immunocytology) was prepared. The results of cytology were assessed for an association with TNM category and cancer grade, based on all patients, and with patient survival, among the R0 resected patients. RESULTS: In conventional cytology 35.5 percent (32/90) of patients with colon cancer and 42.3 percent (47/111) of patients with gastric cancer had a positive cytology. In immunocytology 47.2 percent (17/36) of patients with colon cancer and 46.8 percent (22/47) of patients with gastric cancer were positive. In colon cancer, positive conventional cytology was associated with pT and M category (P=0.044 andP=0.0002), whereas immunocytology was only associated with M category (P=0.007). No association was found between nodal status and immunocytology in colon cancer and with the grading. There was a statistically significant correlation between pT M category and conventional and immunocytology in gastric cancer (P〈0.0015/P=0.007 andP〈0.001/P=0.009, respectively). Positive immunocytology was additionally associated with pN category (P=0.05). In a univariate analysis of R0 resected patients (no residual tumor), positive immunocytology was significantly related to an unfavorable prognosis in patients with gastric cancer only (n=30). Mean survival time was significantly increased in patients with gastric cancer with negative cytology compared with positive cytology (1,205 (standard error of the mean, 91)vs. 771 (standard error of the mean, 147) days;P=0.007) but not in patients with colon cancer (1,215 (standard error of the mean, 95)vs. 1,346 (standard error of the mean, 106) days;P=0.55). CONCLUSIONS: Because microscopic peritoneal dissemination influences survival time after R0 resections only in patients with gastric but not with colon cancer, our results may provide a basis for a decision on additive, prophylactic (intraperitoneal) therapy in gastric but not colon cancer.

    Notes: Abstract Background: In gastric cancer, the level and number of lymph node metastases is useful for predicting survival, and there are several staging systems for lymph node metastasis. The aim of this study was to compare the several lymph node classifications and to clarify the most important lymph node information associated with prognosis using multivariate analysis. Methods: A total of 106 patients with histologically node-positive gastric cancer treated by radical gastrectomy and extended lymph node dissection (D2, D3) were studied. The level of lymph node metastasis was categorized simply as Level I nodes (perigastric, No.1–6), Level II nodes (intermediate, No.7–9), and Level III nodes (distant, No.10–16), irrespective of the tumor location. The Level II nodes included lymph nodes along the left gastric artery, common hepatic artery, and celiac trunk. Results: Overall 5-year survival rate was 51%. Univariate analysis showed that 5-year survival rate was significantly influenced by the level of positive nodes (P 〈 .01), total number of positive nodes (P 〈 .01), number of positive Level I nodes (P 〈 .01), and number of positive Level II nodes (P 〈 .01), in addition to the tumor location (P 〈 .05), tumor size (P 〈 .05), gross type (P 〈 .01), and depth of wall invasion (P 〈 .01). Of these, independent prognostic factors associated with 5-year survival rate were the number of positive Level II nodes (0–1 vs. ≥2) (62% vs. 19%, P 〈 .01) and the depth of wall invasion (within vs. beyond muscularis) (79% vs. 43%, P 〈 .01). Conclusions: Among several staging systems for lymph node metastases, the number of positive Level II nodes provided the most powerful prognostic information in patients with node-positive gastric cancer. When there were two or more metastases in the Level II nodes, prognosis was poor even after D2 or D3 gastrectomy.

    Notes: Abstract Background: In this study we evaluated the expression and clinical significance of pepsinogen C, an aspartic proteinase involved in the digestion of proteins in the stomach, in patients with gastric cancer. Methods: Pepsinogen C expression was examined by immunohistochemical methods in a series of 95 gastric carcinomas. The prognostic value of pepsinogen C was retrospectively evaluated by multivariate analysis taking into account conventional prognostic parameters. Follow-up period of patients was 21.4 months. Results: A total of 25 (26.3%) gastric carcinomas stained positively for pepsinogen C. The percentage of pepsinogen C-positive tumors was higher in well-differentiated (50%) than in moderately differentiated (19.5%) and poorly differentiated (21.9%) tumors (P 〈 .05). Similarly, significant differences in pepsinogen C immunostaining were found between node-negative and node-positive tumors (47.1% vs. 14.7%; P 〈 .001). In addition, statistical analysis revealed that pepsinogen C expression was associated with clinical outcome in gastric cancer patients. Low pepsinogen C levels predicted short overall survival periods in the overall group of patients with gastric cancer (P 〈 .001), and in 71 patients with resectable carcinomas (P 〈 .005). Multivariate analysis according to Cox’s model indicated that pepsinogen C immunostaining was an independent predictor of outcome for both overall and resectable gastric cancer patients (P 〈 .05, for both). Conclusions: The expression of pepsinogen C in gastric cancer may represent a useful biological marker able to identify subgroups of patients with different clinical outcomes.

    Notes: Abstract Recurrent strokes are an important cause of morbidity and mortality. Identification of the causes of recurrence and its treatment may play an essential role in the prevention of further strokes. The aim of our work is to analyze the type and causes of stroke recurrence in a 5-year period and to determine if recurrent stroke is of the same type as index stroke. In a retrospective study, we reviewed the clinical records and database of our hospitals and found a total of 1108 patients admitted because of primary stroke. The patients with recurrent stroke were selected for a comprehensive analysis. Age, vascular risk factors and fatality rates of these patients were compared with those obtained in recurrence-free patients. We identified 135 patients with recurrent stroke. The most frequent type of recurrence was large vessel atherothrombotic stroke followed by the cardioembolic or lacunar stroke. The major contributing factors were hypertension, atrial fibrillation, and cardiomyopathies. The fatality rate did not differ from the overall mortality by stroke in these years, but the majority of deaths occurred in long-term recurrences. The functional status was worse after recurrent stroke than after index stroke. Although any pattern of recurrence is possible. There is a major trend to occur in the same vascular territory by the same pathophysiologic mechanism. Recurrent stroke frequently carries a worse functional status than index stroke. In many patients, despite the appropriate treatment, stroke recurrence was an unavoidable consequence.

    Notes: Abstract Two hundred and twenty-four patients at their first diagnosis of multiple sclerosis (MS) were prospectively followed for a mean period of 9.78 years. We considered as endpoints the time to reach non-reversible disability levels corresponding to EDSS scores of 4.0 and 6.0, and the beginning of a secondary progressive phase in the relapsing-remitting subgroup of patients. An initially progressive course and higher basal EDSS scores proved to be the best predictors of unfavorable prognosis. A greater number of functional systems involved at onset as well as higher residual deficits in pyramidal, visual, sphincteric and cerebellar systems were other factors predictive of a poor outcome, whereas sensory system involvement turnet out to be favorable. A longer first inter-attack interval was associated with a better prognosis. However, overall number of relapses in the first two years of the disease was of no prognostic value. The presence of oligoclonal banding in the cerebrospinal fluid and a cerebral MRI exam strongly suggestive or suggestive of MS in the early phases of the disease were associated with a higher probability of a worse outcome.

    Notes: Abstract The most common mononeuropathy in the lower extremity involves the nerve. We retrospectively evaluated the etiological predisposing factors and clinical-neurophysiological features of 36 patients affected by peroneal mononeuropathy (PM). In 30 patients, a clear predisposing factor was identified. PM was more frequently perioperative (11 cases), associated with axonal involvement. Unexpectedly, PM was not only due to surgery close to the peroneal region, but was mostly associated with hip surgery and, rarely, with thoracic-abdominal surgery. A postural predisposing factor of PM was also frequently observed, usually associated with a pure conduction block. Conversely, most patients with bedridden predisposing factor presented axonal involvement, which was rarely associated with conduction block. In 25 of 36 PM cases, a long-term follow-up lead to an improvement (12 cases) or to good recovery (13 cases) of PM. In conclusion, our study shows that: (1) in most PM cases it is possible to identify a predisposing factor; (2) there is a good correlation between predisposing factor and neurophysiological involvement, and (3) PM usually has usually a good prognosis.

    Notes: Abstract It has been suggested that physical trauma, involving the cervical spinal cord or the brain, and psychological stress may precede MS onset or may influence the disease course, although this hypothesis has mainly come from anecdotal case reports or small uncontrolled or controlled studies. So far there are no studies providing a clear causative relationship between physical trauma (especially head trauma) and MS onset, exacerbation or progression of the disease. On the other hand, recent MRI and experimental studies, supporting the important role of nervous and immune system interactions, particularly by the hypothalamic-pituitary-adrenal axis and by the sympathetic nervous pathways, seem to demonstrate a significant correlation between stress and MS exacerbations. Further, frequent MRI and immunological evaluations should be warranted to objectively document the temporal association between stress and clinical and/or sub-clinical disease activity.

    Notes: Abstract Multiple sclerosis (MS) onset is usually in adult life (age 20–40 years). Discordant data have been reported concerning the frequency of early onset MS (EOMS) that ranges from 2.7% to 5%, whereas there is a general agreement on prevalence of female sex, particularly after puberty. The initial symptoms in EOMS are frequently characterized by visual loss whereas the other functional systems are involved with a variable frequency. Literature data show that EOMS tends to have a relapsing-remitting course, a high rate of recovery from the initial attack, a long time interval between the first and second attacks and a slow progression rate. A poor prognosis is reported in a few cases of EOMS and seems to be related to number of relapses and to the delay between the first and second attacks.

    Notes: Abstract This study was designed to determine whether the restrictive filling transmitral flow velocity pattern is associated with increased plasma levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP). It was also designed to evaluate the prognostic value of these parameters from patients with chronic congestive heart failure (CHF) admitted for episodes of acute decompensation. We performed Doppler echocardiography, measured plasma levels of ANP and BNP in 33 patients at the time of admission, and assessed the subsequent cardiac mortality for 3 months. Eleven patients (33%) had a restrictive filling pattern of deceleration time (DcT) 〈120 ms. Plasma ANP and BNP levels were markedly increased in all patients to 189 ± 145 pg/ml and 865 ± 559 pg/ml, respectively. Seventeen patients (52%) showed more than 700 pg/ml of plasma levels of BNP. There was a significant correlation of DcT with the plasma ANP level (r = −0.41, P = 0.017), and a better correlation of DcT with the plasma BNP level (r = −0.50, P = 0.003). The combined index of both shorter DcT (〈120 ms) and higher plasma BNP levels (〉700 pg/ml) was the best predictor of cardiac mortality by Cox univariate analysis (χ2 = 5.87, P = 0.015). Furthermore, the sensitivity and specificity of this index for the detection of cardiac mortality were 80% and 86%, respectively. In conclusion, the combined analysis of the Doppler transmitral flow velocity pattern and measurement of the plasma BNP level is noteworthy since it is noninvasive and convenient. Moreover, it is extremely useful in predicting the prognosis for patients with chronic CHF admitted for episodes of acute decompensation.

    Notes: Abstract Color M-mode Doppler echocardiography (CMD) has been utilized in assessing left ventricular (LV) filling dynamics. We tested a novel CMD index, the depth of the spatiotemporal maximum of early diastolic inflow (D-maxV) in the left ventricle, to clarify its significance in assessing LV diastolic function. In 26 normal subjects and 32 patients with ischemic heart disease, D-maxV was determined with CMD as the distance from the mitral valve opening point to the center of the aliasing area in early diastole. Transmitral flow velocity was measured with pulsed Doppler. During routine catheterization, high-fidelity LV pressure measurements yielded diastolic variables in patients. D-maxV was significantly lower in the patients than the normals (13.0 ± 7.0 vs 23.4 ± 6.8 mm, P 〈 0.0001). D-maxV exhibited significant linear correlations with the minimal first derivative of LV pressure (r = 0.72, P 〈 0.01), the time constant of isovolumic relaxation (r = −0.67, P 〈 0.01), and LV minimal pressure (r = −0.53, P 〈 0.02) in the patients with wide ranges of peak early to late inflow velocity ratio (0.43–3.9) and deceleration time of early filling (79–293 ms). D-maxV showed an inverse correlation with LV end-diastolic pressure (r = −0.53, P 〈 0.02) and no significant correlation with mean pulmonary capillary wedge pressure. Moreover, Kaplan-Meier analysis focusing on the patients with myocardial infarction revealed that the group with D-maxV 〈 10.4 mm (n = 13) exhibited a lower cumulative cardiac event-free rate than that with D-maxV ≥ 10.4 mm (n = 14) (49.4% vs 92.9% at 5 years, P 〈 0.05). The depth of the spatiotemporal maximum of early diastolic LV inflow velocity reflects LV relaxation and is free of pseudonormalization. Evaluation of the LV relaxation separately from preload may have a prognostic value for myocardial infarction.

    Description / Table of Contents: Summary The present study is aimed at investigating differences between therapists of different theoretical orientations regarding their perception of patients who applied for psychotherapy at a university outpatient department. It was based on the judgements of nine psychodynamically and four cognitive-behaviorally oriented therapists about 144 and 89 patients, respectively, who were assessed after having completed their diagnostic interviews. Cognitive-behaviorally oriented therapists perceived the quality of the working alliance to be better and their feelings of sympathy towards the patients they had interviewed to be stronger than did psychodynamically oriented therapists. Psychodynamic therapists saw higher distress in the early childhood, whereas behavior therapists rated patients’ present coping abilities higher. In addition, the latter judged patients’ motivation, a common understanding of the illness, several prognostical factors and the global prognosis more favourable. Regarding the frequencies of disorder categories and the severity of functional restriction due to the disorders no differences were found. The results are discussed from both a cognitiv-behavioral and a psychoanalytical point of view.
    Notes: Zusammenfassung Die vorliegende Arbeit hat das Ziel, Unterschiede in der Wahrnehmung des Patienten bei der psychotherapeutischen Erstuntersuchung je nach theoretischer Orientierung des Diagnostikers zu untersuchen. Sie basiert auf den Einschätzungen von neun tiefenpsychologisch/analytisch und vier kognitiv-verhaltenstherapeutisch orientierten Therapeuten, die 144 bzw. 89 Patienten einer universitären psychotherapeutischen Poliklinik nach dem Erstgespräch beurteilten. Kognitiv-verhaltenstherapeutisch orientierte Erstuntersucher nahmen die Qualität der therapeutischen Arbeitsbeziehung signifikant als besser und die Patienten, die sie untersuchten, als sympathischer wahr. Tiefenpsychologisch orientierte Diagnostiker sahen stärker ausgeprägte frühkindliche Belastungen, wohingegen Verhaltenstherapeuten die aktuelle Bewältigungskompetenz der Patienten höher bewerteten. Zudem schätzen sie die Motivation des Patienten, das gemeinsame Krankheitsverständnis, verschiedene prognostische Faktoren sowie die globale Prognose als günstiger ein. Hinsichtlich der Häufigkeit diagnostischer Kategorien und der Beurteilung der Beeinträchtigungsschwere fanden sich keine Unterschiede je nach therapeutischer Orientierung. Die festgestellten Unterschiede werden sowohl vor einem kognitiv-verhaltenstherapeutischen als auch vor einem psychoanalytischen Theoriehintergrund interpretiert.
