New combination chemotherapy programme for bladder cancer.

Forty patients with either metastatic, post-radiotherapy recurrent, or poor prognosis locally advanced transitional cell carcinoma of the bladder were treated in a new combination chemotherapy programme with methotrexate, vinblastine, mitozantrone and JM8 (carboplatin); 33 patients were assessable for response. There were 9 complete responses (27%), 12 partial responses (36%) and 7 disease stabilizations (21%); 5 patients (15%) had progressive disease. The median duration of complete response has not been reached and is in excess of 9 months (range 4- greater than 18 months). This regimen was without significant toxicity and this is in contrast with M-VAC, which is thought to be currently the most effective treatment for urothelial cancer.
