M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) chemotherapy for transitional cell carcinoma: the Princess Margaret Hospital experience.
We treated 41 patients with transitional cell carcinoma with methotrexate, vinblastine, doxorubicin and cisplatin chemotherapy. Median patient age was 56 years. Of the patients 33 had either distant metastases or locoregional disease that could not be cured by an operation or radiation. Of these patients 30 had measurable disease and 12 responded (4 complete and 8 partial responses, response rate 40 per cent, 95 per cent confidence limits 23 to 59 per cent). Only 2 of these patients remain with an unmaintained complete response at 34 and 52 months. Of 5 patients 3 responded who were treated with neoadjuvant methotrexate, vinblastine, doxorubicin and cisplatin for locally advanced bladder cancer before radiation or cystectomy, and only 1 of these patients is free of disease. The remaining 3 patients were treated postoperatively because they were at high risk for recurrence and all are well. Toxicity of the regimen was severe: 41 per cent of the patients experienced neutropenic sepsis and 54 per cent required hospitalization for management of toxic complications. Three patients experienced pulmonary embolism and 1 had deep vein thrombosis. There was 1 drug-related death of sepsis. Although a patient occasionally may have long-term benefit from this chemotherapy our results suggest caution in the widespread application of this protocol.
