Carboplatin, methotrexate and vinblastin (Carbo-MV) for advanced urothelial cancer. A phase II trial.

Fifteen patients with advanced urothelial cancer were treated with carboplatin 300 mg/m2, methotrexate 30 mg/m2, and vinblastin 3 mg/m2 on day 1 and the same dosage of methotrexate and vinblastin on days 15 and 22. Six patients were pretreated with radiotherapy and or chemotherapy; 7 patients had impaired renal function due to obstructive uropathy. Eight patients achieved a partial remission; 4 patients achieved a minor remission or stabilization of progressive disease. Mean duration of response was 8+ month (2+ to 12+ month). Subjective tolerance of the treatment was excellent but there was considerable bone marrow toxicity in the pretreated patients. The data show that Carbo-MV (carboplatin, methotrexate, and vinblastin) is effective and subjectively well tolerated in advanced urothelial carcinoma.
