    Notes: Summary In order to develop a more dose-intensive induction regimen for the treatment of far-advanced testicular tumours, the German Cooperative Group for Testicular Tumours started a dose-escalation trial of cisplatin, etoposide and ifosfamide. At the first dose level 18 patients with advanced testicular cancer (Indiana University classification) received cisplatin 25 mg/m2, etoposide 120–150 mg/m2 and ifosfamide 1.2 g/m2 for 5 days every 3 weeks. Of these, 13 patients (72%) became tumour-free, 2 achieved a stable, marker-negative partial remission, 2 had progressive disease and 1 patient died ofClostridium sepsis. The main toxicity was myelosuppression with a white blood cell nadir of 900/μl and a thrombocyte nadir of 47000/μl. Granulocytopenic fever occurred in 43% of all cycles. At the second dose level 15 patients received cisplatin 30 mg/m2, etoposide 150 mg/m2 and ifosfamide 1.6 g/m2 five times every 3 weeks together with s.c. recombinant granulocyte/macrophage-colony-stimulating factor (GM-CSF) 10 μg/kg on days 6–15. Acute toxicity was severe with a white blood cell nadir of 300/μl and thrombocyte nadir of 11 000/μl. The duration of the thrombocytopenia increased with cycle number; 63% of all cycles were associated with granulocytopenic fever and in 83% platelet transfusions were required. One patient died from acute renal failure andAspergillus sepsis; 3 patients experienced adverse reactions to GM-CSF, requiring omission of this drugs in 2; 33% had grade 3 or 4 mucositis. At this dose level 8 patients (53%) became tumour-free, 4 patients (26%) had marker normalization with irresectable residual disease and 2 patients were treatment failures. Though acute toxicity was severe at this dose level, there was no unexpected or unmanageable organ toxicity and thus patients are now entered at dose level 3, which consists of cisplatin 30 mg/m2, etoposide 200 mg/m2 and ifosfamide 1.6 g/m2 for 5 days and GMCSF 10 μg kg−1 day−1 on days 6–15 s.c.

    Notes: Abstract We report biochemical data on a child with MSUD who underwent peritoneal dialysis for severe metabolic imbalance. In confirmation of earlier data, the BCKA/BCAA ratios in blood had been found to be fairly stable in this patient during long-term dietary therapy. The child became comatose at comparatively low levels of leucine and KICA (ca. 2 mM each). At this time the blood/cerebrospinal fluid ratio for BCAA's and BCKA's was markedly diminished. During peritoneal dialysis, peritoneal clearance was highest for KIVA, but less for MEVA and BCAA's (40–50% or urea clearance), and least for the allegedly most toxic metabolite, KICA. The differences for BCKA's may be due to their differential protein binding. Given these individual differences, 1.8 to 8.7 initial plasma volumes were cleared in 14h with 24.21 of dialysis fluid. In the same time, urinary excretion of BCAA's and BCKA's was much less efficient. The data are discussed with regard to the pathobiochemical significance of high tissue levels of branched chain acids. A quantitative comparison between peritoneal dialysis and exchange transfusion is not yet possible.

    Notes: Abstract Background:To evaluate the activity of MTA plus cisplatin inchemotherapy-naïve patients with non-small cell lung cancer (NSCLC). Patients and methods:Thirty-six chemotherapy-naïve patientswith NSCLC received 500 mg/m2 MTA plus 75 mg/m2cisplatin every 21 days, with 4 mg dexamethasone orally twice daily on the daybefore, of, and after MTA administration. Results:Median age was 58 years. WHO performance status was0–2. Eighteen patients each had stage IIIB and IV disease. Seventeenpatients each had squamous-cell and adenocarcinoma; two had undifferentiateddisease. Fourteen patients (39%; 95% confidence interval:23%–57%) showed partial response; seventeen (47%)had stable disease. Median survival was 10.9 months. Twenty-one patients(59%) experienced grade 3 or 4 granulocytopenia without fever orinfection. Five (14%) and six (17%) patients experienced grade3 anemia and grade 3 or 4 thrombocytopenia, respectively. Nonhematologicaltoxicities included grade 3 nausea in two patients (6%), and grade 3and 4 diarrhea in one patient (3%) each. One patient each experiencedgrade 4 ALT and grade 3 bilirubin and AST elevations. Conclusions:MTA plus cisplatin is well tolerated and activeagainst NSCLC. Further studies of this combination are warranted.

    Notes: Abstract Background: This randomised study was designed to determine the responserate, survival and toxicity of single-agent gemcitabine andcisplatin–etoposide in chemo-naïve patients with locally advancedor metastatic non-small-cell lung cancer. Patients and methods: Gemcitabine 1,000 mg/m2 was given asa 30 min intravenous infusion on days 1, 8, 15 of a 28-day cycle, cisplatin100 mg/m2 on day 1, and etoposide 100 mg/m2on days 1 (following cisplatin), 2 and 3. Major eligibility criteria includedhistologically confirmed non-small-cell lung cancer, measurable disease,Zubrod PS 0–2; no prior chemotherapy, no prior radiation of the measuredlesion, and no CNS metastases. Results: 146 patients were enrolled, 71 patients on gemcitabine and 75patients on cisplatin–etoposide. Patient characteristics were wellmatched across both arms. Sixty-six gemcitabine patients and 72cisplatin–etoposidepatients were evaluable. Partial responses were seen in 12 gemcitabinepatients (18.2%; 95% CI: 9.8–30) and 11cisplatin–etoposide patients (15.3%; 95% CI:7.9–25.7).Early indications show no statistical differences between the two treatmentswith respect to time to disease progression or survival. Haematological andlaboratory toxicity were moderate and manageable. However, hospitalisationbecause of neutropenic fever was required for 6 (8%)cisplatin–etoposide patients but not for any gemcitabine patients.Non-haematological toxicity was more pronounced with significant differencesin nausea and vomiting (grade 3 and 4: 11% gemcitabine vs. 29%cisplatin–etoposide; despite the allowance for 5-HT-3antiemetics during the first cycle of cisplatin–etoposide), and alopecia(grade 3 and 4: 3% gemcitabine vs. 62%cisplatin–etoposide). Conclusions: In this randomised study, single-agent gemcitabine was atleast as active but better tolerated than the combinationcisplatin–etoposide.
