    Notes: Summary In 43 patients with inoperable bronchogenic carcinoma — 32 small cell and 11 squamous or large cell — Angiotensin-Converting-Enzyme (ACE) activity in serum was determined before and every 3–5 weeks during cytotoxic chemotherapy. ACE-activity prior to therapy was 10.7 U ± 1.17 SE as compared to the normal values 20.4 U ± 1.8 SE which was statistically significant (p〈0.01). There was no significant difference between the basal values of patients with small cell and not small cell-carcinoma of the lung. Only for patients with small cell-carcinoma of the lung a significant rise in ACE-activity could be obtained. Mean values of these patients reached normal levels in case they had complete remission, which was achieved in the limited disease group in 82% of patients. The present data suggest, that ACE-activities in serum correspond well to the clinical course in patients with small cell carcinoma of the lung. The decision on the individual mode of therapy may thus become more substantiated by serial determinations of ACE in the course of treatment.

    Description / Table of Contents: Zusammenfassung Seit 1975 wurden 140 Patienten mit retroperitoneal-metastasierten nicht-seminomatösen Hodentumoren nach Orchiektomie und retroperitonealer Lymphadenektomie sequentiell alternierend mit den Zytostatika-Kombinationen Velbe/Bleomycin und Adriamycin/Cisplatin plus/minus Radiotherapie behandelt. Davon erhielten 68 Patienten nach totaler retroperitonealer Lymphadenektomie mit postoperativ normalisierten Tumormarkern (Stadium IIA) 6 Chemotherapie-Kurse, woran sich bei 35 Patienten eine Strahlentherapie anschloß. Vierzig Patienten wurden nach subtotaler retroperitonealer Lymphadenektomie oder bei postoperativ erhöhten Tumormarkern (Stadium IIB) und 32 Patienten nach palliativer Lymphadenektomie (Stadium IIC) mit mindestens 12 Chemotherapie-Kursen und fakultativer intermittierender Radiotherapie und/oder Relaparotomie behandelt. Der Vergleich der Behandlungsergebnisse bei den Stadien IIA und IIB ergab unabhängig von der zusätzlichen Radiotherapie nach der „Life-table“-Methode Vier-Jahres-Überlebensraten zwischen 80 und 100%. Diese günstigen Resultate sind mit den Ergebnissen bei 34 nicht adjuvant behandelten Patienten ohne histologisch nachweisbare retroperitoneale Metastasierung (Stadium I) vergleichbar. Ausdruck einer statistisch signifikant schlechteren Prognose bei fortgeschrittener retroperitonealer Metastasierung ist eine Vier-Jahres-Überlebensrate von 12% bei den Patienten im Stadium IIC.
    Notes: Summary Following orchiectomy and retroperitoneal lymph node dissection (RND) 140 patients with stage II non-seminomatous testicular cancer were treated by sequential combination chemotherapy consisting of vinblastine/bleomycin and adriamycin/cis-dichlorodiammineplatinum(II) (DDP), plus/minus radiotherapy. 68 stage IIA-patients (complete RND and normal tumor-markers thereafter) received 6 courses of chemotherapy, followed by radiotherapy in 35 patients. 40 stage IIB-patients (minor residual disease after RND or elevated tumor-markers after RND) and 32 stage IIC-patients (advanced residual disease after RND) were treated by at least 12 chemotherapy courses and optional intermittent radiotherapy and/or relaparotomy. In stage IIA and IIB disease the actuarial 4-year survival rates were between 80 and 100%. These favourable results were not significantly influenced by additional radiotherapy and corresponded to the survival rates for 34 stage I-patients. For stage IIC-patients the prognosis was significantly worse with a 12% 4-year survival rate.

    Notes: Abstract To evaluate treatment-related changes of the reticulin stain-measured fibrosis in Ph1+-CML, a clinicopathological study was performed on sequential trephine biopsies of the bone marrow following either interferon (IFN) or busulfan (BU) monotherapy. Using the monoclonal antibody CD61 for the identification of megakaryopoiesis and Gomori's silver impregnation method, number of megakaryocytes and density of argyrophilic (reticulin and collagen) fibers were determined by morphometry. We studied specimens from 26 patients with IFN-alpha 2b (including nine patients with additional IFN gamma) therapy and from 23 patients who had received BU. In both groups, repeated bone marrow biopsies (total 125) revealed a significant increase in the fiber content, as well as in the number of megakaryocytes during treatment. To assess the dynamics of myelofibrosis more precisely, computation of differences in the degree of fiber density between the first and last examination was carried out. Regarding the considerable variations in the biopsy intervals, a so-called myelofibrosis progression index (MPI) was calculated. Following this rationale, we were able to demonstrate that, in comparison to the BU-group, speed of progression of bone marrow fibrosis was significantly increased in CML patients treated with IFN. Preliminary statistical analysis indicated a relationship between myelofibrosis on admission, which was always associated with increased growth of megakaryocytes, and the MPI with survival. Even when these parameters were regarded, prognosis was significantly more favorable in the IFN-treated patients. The failure of IFN and BU to inhibit the evolution of myelofibrosis may be related to several conversely acting pathomechanisms. Among others, the inability of both therapeutic agents to reduce the number of megakaryocytes more effectively should be taken into consideration.

    Notes: Summary During long-term interferon α-2b (IFN) therapy of Philadelphia chromosome-positive chronic myelogenous leukemia (CML) patients, short-term effects of tumor necrosis factor α (TNF) on peripheral leukocyte counts, as well as cortisol and corticotropin (ACTH) release were studied. TNF (40–160μg/m2) was given as a 2-h infusion on 5 consecutive days every 3 weeks, in addition to s.c. daily IFN injections (4 mio U/m2), to four (two male/two female) patients, who had been treated for more than 8 months with IFN and additionally for 0–7 months with TNF. Leukocyte counts, cortisol, and ACTH were determined at 30-min intervals between 4 p.m. and midnight. Profiles were determined the day before and on day 1 of TNF therapy. Leukocyte numbers decreased 30 min after start of TNF administration and increased 30–60 min later with a rebound until the next TNF application. The increase of leukocyte counts was due mostly to neutrophil granulocytes. ACTH levels increased 30 min, cortisol 60 min, and leukocyte counts 90 min after start of TNF infusion. Metopirone, an inhibitor of cortisol synthesis given to one patient, suppressed the TNF-induced stimulation of cortisol secretion and subsequent increase of leukocyte counts, while ACTH blood levels were enhanced. It was concluded that leukocyte count increases after TNF/IFN administration might be related to TNF-evoked cortisol secretion.

    Notes: Summary Aclacinomycin A (ACM) is a new anthracycline antibiotic with a reduced cardiac toxicity in animal models. A phase II study was performed in a total of 25 patients, 23 of whom are evaluable for response. All suffered from recurrent and advanced tumors. Pretreatment consisted of at least four different chemotherapeutic agents (range: 4–9). Lung cancer patients (3/9) were irradiated to the mediastinum. Eighteen patients were pretreated with doxo- or daunomycin. The dose for solid tumors was 2–3 mg/kg given on 3 consecutive days every 3 weeks. Leukemia patients received a daily dose of 20 mg/m2, and standard response criteria were used. Marked reductions of leukocyte counts were achieved in leukemia patients. The overall response rate was about 15% in solid tumors, but major objective responses (CR+PR) have not been observed. Myelosuppression was commonly moderate in solid tumor patients, nausea and vomiting were rare, and alopecia was not induced. Cumulative cardiotoxicity was not evaluated in this trial. Treatment with ACM requires further investigation in acute leukemias and solid tumors, not pretreated with anthracycline antibiotics.

    Notes: Summary Seventy-three evaluable patients with advanced measurable solid tumors were given cisdichlorodiammineplatinum (II) (DDP) at a dose of 20 mg/M2 IV for 1–5 days every 3 weeks, and 19 patients who failed on this low dose DDP protocol received a single high dose of 100 mg/M2 IV once every 3 weeks. Forty-six patients had received prior chemotherapy, and 29 patients were untreated. Results included four complete responses (5.5%) in malignant melanoma, spindle-cell sarcoma, adrenal carcinoma, and bladder carcinoma lasting 2 to 4 months. In 21 patients (28.8%), partial responses were achieved. Twenty-two patients (30.1%) showed stable disease and 26 (35.6%) had tumor progression. A response rate of 25% (4/16 patients) was found for malignant melanoma, 45.5% (5/11) for nonsmall-cell lung cancer, and 35.3% (6/17) for sarcomas of various types. One patient with teratocarcinoma, who relapsed on low-dose DDP, had another partial remission for 4 months after high-dose therapy. Toxicity was most commonly seen with gastrointestinal side effects and myelosuppression. Cumulative nephrotoxicity was prevented by prehydration and/or treatment with furosemide or mannitol.
