Vindesine for metastatic malignant melanoma. A phase II trial.

Sixteen patients, 13 of whom had received prior chemotherapy, were treated with vindesine for advanced malignant melanoma. Previous treatment included vinca alkaloids in six. Thirteen patients received vindesine, 4 mg/m2 and three received vindesine, 3 mg/m2 by weekly I.V. injection. There were two partial (12%) and no complete responses among all of the patients. Both responses occurred in subcutaneous lesions and lasted for 4 and 6 weeks, respectively. Fifteen patients could be evaluated for treatment-related toxicity. The most common side effect was modest leukopenia (less than 3000/microliter) in 10 patients (67%). The lowest leukocyte count recorded was 1100/microliter. Thrombocytopenia was not encountered. Neurotoxicity, manifest most commonly as mild or moderate peripheral paresthesiae, was seen in eight patients (53%).
