    Beschreibung / Inhaltsverzeichnis: Résumé Trente six patients admis pour l'exérèse chirurgicale d'un léiomyosarcome gastro-intestinal dans l'unité de chirurgie II du Département de Chirurgie à Karrazawa University Hospital, Karrazawa, Japan, ont été sélectionés pour cette étude. Des renseignements concernant la survie était disponibles chez 32 patients. Les données clinico-pharmacologiques comprenant le site et la taille de la tumeur, la cellularité, l'index mitotique et le caractère diploÏde de l'ADN ont été analysés. Les résultats correlaient positivement avec le pronostic. Treize patients (41%) avaient des métastases à distance et/ou des récidives. Les métastases d'origine hématogène étaient très fréquentes. La récidive locale et la survenue de métastases à distance étaient correlées de faÇon significative avec la survie (p〈0.001), la localisation de la tumeur (p〈0.03), la taille de la tumeur (p〈 0.04) et le traitement chirurgical (p=0.05), mais pas avec le type de diploÏdie de l'ADN (p=0.06). Ni la cellularité ni l'index mitotique ne correlaient avec la survie de faÇon significative. De plus plusieurs patients ayant une récidive locale associée à des métastases à distance ont eu des survies prolongées après résection des récidives. Au vue de ces résultats, un traitement chirurgical agressif des récidives semble efficace.
    Kurzfassung: Resumen Se seleccionaron 36 pacientes entre aquellos hospitalizados para resectión quirÚrgica de leiomiosarcomas del tracto gastrointestinal en el Departamento de Cirugía II, Hospital de la Universidad de Kanazawa, Japón, y los departamentos de círugía afiliados, para el presente estudio; la informatión relativa a sobre vida pudo ser obtenida en 32 de ellos. Las variables clinico-farmacológicas, taies como tamaño del tumor, ubicación, celularidad, indice mitótico y patrón ploidial de DNA fueron analizadas; los resultados aparecieron correlacionandose con el pronóstico. Trece (41%) de los pacientes se presentaron con metastasis distantes y/o recurrencias, las metastasis hematogénicas siendo el tipo predominante de recurrencia. Las recurrencias locales y/o las metástasis distantes aparecieron significativamente correlacionados con la sobrevida (p〈 0.001), así como con la ubicación del tumor (p〈0.03), el tamaño del tumor (p〈0.04), el tratamiento quirÚrgico (p= 0.05) y el patrón ploidial de DNA (p=0.06). Ni el índice mitótico ni la celularidad demostraron correlación con la sobrevida. Además, algunos pacientes con recurrencia local o con metastasis distantes sobrevivieron por largo periodo después de resección de tumores recurrentes. En vista de estos resultados, la resección quirurgica agresiva puede representar una modalidad eficaz de tratamiento de la recurrencia.
    Notizen: Abstract Thirty-six patients who were admitted for surgical resection of leiomyosarcomas of the gastrointestinal tract to the Department of Surgery II, Kanazawa University Hospital, Kanazawa, Japan and its affiliates are included in the study. Follow-up data on survival is available for 32 patients. The clinico-pharmacologic variables, such as tumor site, tumor size, cellularity, mitotic index, and DNA ploidy pattern were analyzed and the results proved to correlate with the prognosis. Thirteen (41%) of the patients presented with distant metastases and/or recurrences, with hematogenous metastasis being the predominant type of recurrence. Local recurrences and/or distant metastases were significantly correlated with survival (p 〈0.001), as was tumor site ( p 〈0.03), tumor size ( p 〈 0.04), surgical treatment ( p =0.05), and DNA ploidy pattern ( p =0.06). Neither the mitotic index nor the cellularity proved to be significantly correlated with survival. Furthermore, some of the patients with local recurrences or distant metastases survived long after resection of recurrent tumors. In view of the results, aggressive surgical resection may be an efficient treatment of recurrences.

    Beschreibung / Inhaltsverzeichnis: Résumé La perfusion péritonéale continue hyperthermique (PPCH) avec des agents anticancéreux comme le mitomycine C et la cis-platine avec sérum physiologique chauffé a été instaurée lorsqu'une carcinose d'origine gastrique a été trouvée. Les effets de la PCH ont été évalués chez 16 patients lors d'un second-look (SL). Cette étude concerne 41 patients avec carcinose péritonéale sans métastase hépatique observés au cours des 6 dernières années. La survie globale médiane était de 437 jours (extrêmes 28 à 1925 jours): le taux de survie a 3 ans était de 28.5%. Les lésions avaient diminué de façon notable chez 7 (50%) de 14 patients. L'ascite a disparu dans 7 des 9 cas. Une survie à long terme (3 ans) a été notée dans 4 cas. Les effets secondaires ont été une insuffisance rénale dans 2 cas (5%), une leucopénie dans 2 cas (5%) et une perforation de l'intestin grêle dans un cas (2%). Les résultats suggèrent que la PPCH est efficace dans le traitement du cancer gastrique avec dissémination péritonéale.
    Kurzfassung: Resumen La perfusión hipertérmica continua (PHTC) con agentes anticancerosos (mitocina G y cisplatino) y solutión salina fue realizada en pacientes con cáncer gástrico con diseminación peritoneal después de resección de la lesión primaria, y el efecto de PHTC fue determinado mediante reexploración (operación de “second look”, OSL). La población de pacientes está constituída por 41 casos de cáncer gástrico con diseminación peritoneal pero sin metástasis hepáticas, tratdos en el curso de los últimos 6 años. La sobrevida media global fue de 437 dias (rango 28 a 1925 días) desde la PHTC hasta la muerte y la tasa de sobrevida a 3 años fue 28.5%. La OSL reveló una notoria disminución de la diseminación peritoneal en 7 (50%) de 14 casos y desaparición de la ascites después de sólo un ciclo de PHTC en 7 de 9 casos con ascitis. Sobrevida de 3 años ocurrió en 4 casos. Los efectos colaterales fueron insuficiencia renal en 2 casos (5%), leucopenia en 2 casos (5%) y perforación del intestino delgado en 1 caso (2%). Los anteriores resultados sugieren que la PHTC es eficaz en el tratamiento del cáncer gástrico con diseminación peritoneal.
    Notizen: Abstract Continuous hyperthermic peritoneal perfusion (CHPP) with anticancer agents (mitomycin C and cisplatin) in warm saline was performed in patients with peritoneal dissemination of gastric cancer following resection of the primary lesion. The effect of CHPP was examined by a second-look operation. This study includes 41 cases of gastric cancer with peritoneal dissemination but without liver metastasis treated during the past 6 years. The overall median survival was 14.6 months to 64.2 months from CHPP to death and the 3-year survival rate was 28.5%. Second look surgery revealed a remarkable diminution in the degree of peritoneal dissemination in 7 (50%) of 14 patients with disappearance of ascites after only one course of CHPP in 7 (77.8%) of 9 patients. Long-term 3 year-survival was noted in 4 (9.8%) patients on CHPP. Side effects were renal insufficiency in 2 (5%) patients, leukopenia in 2 (5%) patients, and perforation of the small intestine in 1 (2%) patient. These results suggest the effectiveness of CHPP in the treatment of gastric cancer with peritoneal dissemination.

    Notizen: Abstract Paraffin-embedded tumor samples from 151 patients with stage I gastric cancer were analyzed by DNA flow cytometry, and 80 patients recieved an infusion of bromodeoxiurudine (BrdU) to determine S-phase fraction. S-phase fractions of tumors were measured by the immunohistochemical method using anti-BrdU monoclonal antibody. Of the 151 patients, 81 (54%), and 70 (46%) showed diploid and aneuploid patterns. There was no significant association between DNA ploidy and wall invasion, histologic type, or lymphatic invasion. Aneuploid tumors were associated with positive-vessel invasion. When the DNA ploidy and clinicopathological parameters were simultaneously entered into the Cox regression model, DNA ploidy and wall invasion emerged as independent prognostic parameters. Aneuploid tumors had significantly higher values of BrdU labeling indices than diploid ones. These results indicate that the determination of DNA ploidy patterns may be an important prognostic factor in patients with stage I gastric cancer, and may be useful in deciding the therapeutic schedule of patients with gastric cancer.

    Notizen: Abstract We report herein the unusual case of a 59-year-old woman with Plummer-Vinson syndrome who developed gastric cancer. The patient had a longstanding history of dysphagia and iron deficiency anemia, for which she has sporadically taken iron deficiency anemia, for which she had sporadically taken iron supplements that improved the dysphagia to some extent, but not completely. Owing to her tolerance of the dysphagia, she had not been taking iron supplements for the past 17 years. On admission, she was in fair nutritional condition and not anemic. Blood chemistry results were all normal, including the serum iron level. Gastrointestinal radiographic series demonstrated cervical esophageal webs and advanced gastric cancer. Her dysphagia was successfully treated by endoscopic bougienage through the webs, and a distal partial gastrectomy with nodal dissection was performed. Histology of the resected stomach revealed atrophic mucosal change and, by chance, an adenomatous lesion in addition to adenocarcinoma. Her postoperative course was uneventful and she is now well, without any signs of recurrence. Although Plummer-Vinson syndrome is known to be associated with upper alimentary tract cancers, gastric cancer is extremely rare. A discussion on the etiology of Plummer-Vinson syndrome and its link with potential carcinogenesis follows this case report.

    Notizen: Abstract A prospective evaluation of the accuracy of real-time ultrasonography (US), computed tomography (CT), infusion hepatic angiography (IHA), and computed tomography during arterial portography (CT-AP) was performed on 65 resected liver metastases of colorectal cancers. The total detection rate was 58.5 percent for US, 56.3 percent for CT, 554 percent for IHA, and 86.2 percent for CT-AP. The sensitivity of 29 lesions with diameters of smaller than 1 cm was 65.5 percent for CT-AP, CT found only two, and both US and IHA localized no more than three. The smallest lesions detectable by CT-AP were as small as 0.4 cm in diameter. CT-AP proved most useful in detecting the liver metastases, and the use of this techique is recommended for preoperative planning of hepatectomy on patients with liver metastases.

    Notizen: Abstract We examined serum NCC-ST 439 for its significance as a tumor marker of large bowel cancer in 121 patients with primary and 36 with recurrent large bowel cancer. Serum NCC-ST 439 was positive in 27.3 percent of the former and 66.7 percent of the latter. It was false-positive in only 5.6 percent of patients with benign diseases. Positive serum NCC-ST 439 correlated with lymph node and liver metastases. The combination assay for NCC-ST 439, CEA, and CA19-9 was positive in 49.6 percent of the patients with primary tumors and 88.9 percent of those with recurrent tumors; in other words, the diagnostic accuracy improved. The results demonstrated that the determination of serum NCC-ST 439 in large bowel cancer might be useful in cancer staging and that NCC-ST 439, if used in combination with CEA, is particularly useful in diagnosing recurrences because of its improved diagnostic accuracy.

    Thema: Medizin
    Notizen: Abstract We report a rare case of gallbladder cancer associated with a common bile duct neuroma, and a cystic liver lesion with histologic findings similar to an inflammatory pseudotumor, in a patient who had had no previous abdominal surgery. The patient was a 62-year-old man whose major complaint was fever. Ultrasonography and a computed tomography scan revealed gallstones, an elevated lesion in the gallbladder, and a cystic liver lesion. Endoscopic retrograde cholangiopancreatography demonstrated stenosis of the common bile duct. Cultures of the cystic fluid and gallbladder bile were positive forStaphylococcus aureus. The patient underwent hepatectomy (inferior S4, S5, and S6), cholecystectomy, resection of the common bile duct, and right hemicolectomy. The resected specimens revealed gallbladder cancer with the microscopic appearance of a papillary adenocarcinoma, and a 12×4.5×3.5 cm cystic liver lesion with a wall 7 mm thick. Histologic studies of the wall of the cystic liver lesion revealed infiltration by histiocytes and plasma cells, and the presence of fibrous connective tissue, which findings are characteristic of inflammatory pseudotumors. A 9×6 mm elevated lesion, with the microscopic appearance of a neuroma, was resected from the common bile duct.

    Notizen: Abstract To clarify whether or not the lymphatic routes that have long been generally accepted are indeed correct, we retrospectively examined the clinical records of patients with solitary lymph node metastasis from gastric carcinoma. From 735 patients gastrectomized with lymph node dissection (more than D1), 51 (7%) were histologically proven to have only one lymph node involved. In 44 of these 51 patients, the involved nodes were all in the perigastric region (N1). There were also 7 patients with a jumping metastasis to the N2–N3 nodes. Three of them were found along the left gastric artery (#7 according to Japanese classification) and the other 4 were found along either the common hepatic artery (#8) or the proper hepatic artery (#12). The depth of invasion was submucosal in 2, proper-muscular in 2, subserosal in 1, and serosa-exposed in 2, and the conclusive stage was II in 2, IIIa in 3, and IIIb in 2. However, 1 of these patients died of liver cirrhosis and 2 died of pneumonia, while the other 4 were still alive at the time of this report more than 5 years after surgery. These results suggest that not every sentinel node is located in the perigastric region near the primary tumor and that, if the preoperative examination indicates submucosal invasion, then a systematic regional lymph node dissection should therefore be carried out.
