Aim: Immunotherapy with interferon‐alfa (IFN‐alfa) is used in a variety of diseases in‐ and outside clinical trials (e.g. chronic hepatitis, melanoma, chronic myelogenous leukemia, renal cell carcinoma, multiple myeloma). Treatment with IFN‐alfa can cause (severe) neuropsychiatric side effects. The purpose of this article is to give an updated review of(More)
The semisynthetic taxoid docetaxel was investigated in a phase II study in non-chemotherapy pretreated patients with metastatic urothelial cell cancer. Thirty patients (median age 61, range 45-72) were treated with docetaxel 100 mg m(-2) administered as a 1-h infusion every 3 weeks. Of 29 evaluable patients, four achieved a complete response and five a(More)
Fifty-seven patients with metastatic melanoma were treated with interleukin 2 (IL-2) 7.8 MIU m-2 day-1 as a continuous infusion for 4 days combined with interferon alpha (IFN-alpha) 6 MIU m-2 day-1 subcutaneously on days 1 and 4. The cycle was repeated every 2 weeks for a maximum number of 13 cycles. Of the 51 evaluable patients, one (2%) achieved a(More)
We investigated the reconstitutive potential of haematopoietic progenitor cells collected in autologous whole blood during multicycle dose-intensified chemotherapy. Forty patients with metastatic solid tumours were treated with up to six cycles of cisplatin and escalating doses of ifosfamide every 14 days. Cisplatin was administered in 3% sodium chloride(More)
Forty-three patients with metastatic melanoma were treated with a 5 day (18 patients) and a 3 day (25 patients) schedule of high-dose IL-2 11.7 MIU m2 and IFN-alpha 3 MIU m2 i.v. by bolus administration every 8 h, repeated every 21 days for a total of three courses. The 5 day schedule resulted in a high response rate of 41% (CI 18-67%), but was accompanied(More)
The aim of this study was to evaluate the effect of pegylated interferon-alpha (PEG-IFN-α) on the plasma citrulline/arginine ratio, regarded as an index of nitric oxide (NO) synthesis, in patients with high-risk melanoma. Forty patients were randomly assigned to either PEG-IFN-α treatment (n = 22) or to observation only (control group, n = 18). The(More)
In a phase II study, 27 patients with metastatic breast cancer were treated with oral etoposide as second-line chemotherapy at a dose of 50 mg/m2/day for 21 days, which courses were repeated every 4 weeks. Twenty-one patients were evaluable for response, and twenty-five for toxicity. In two (10%) patients a partial response was observed with a duration of(More)
