Carboplatin, methotrexate, and vinblastine in outpatients with advanced transitional cell carcinoma of the bladder

Twenty outpatients with locally advanced (inoperable) or metastatic transitional cell carcinomas of the bladder were treated with carboplatin (300 mg/m2 i.v., day 1) + methotrexate (40 mg/m2 days 1 and 8) + vinblastine (6 mg/m2 days 1 and 8) (CaMV), every 4 weeks. One patient died of disease progression before completing at least 2 cycles of chemotherapy. Seven patients (35%) obtained a partial response; 8 had disease stabilization (40%) and 4 progressed (20%). Median duration of response was 3 months (range: 3-9), and median overall survival was 12+ months (range: 1-18+). None of the patients suffered grade IV toxicities, and no nephro-, neuro-, or ototoxicity was observed.
