Evaluation of systemic chemotherapy with methotrexate, vinblastine, Adriamycin, and cisplatin for advanced bladder cancer

Summary In a cooperative study of the Japanese Urological Cancer Research Group for Adriamycin, the usefulness of chemotherapy with methotrexate, vinblastine, Adriamycin, and cisplatin (M-VAC therapy) in treating advanced or recurrent bladder cancer was examined. Evaluation of the clinical responses obtained in 86 evaluable patients revealed 13 complete responses, 29 partial responses, 4 minor responses, 19 cases of no change, and 21 cases of progressive disease. The overall response rate was 48.8% (42/86). The rate of response to M-VAC therapy at each disease site was as low as 21.4% (3/14) in bone lesions but exceeded 40% in the primary lesion, the lymph nodes, the lung, the liver, and other lesions. The clinical response to M-VAC therapy was not significantly influenced by the performance status of the patients, the dose intensity, or previous therapy. The median duration of response for the 42 responders was 22.7 weeks (range, 8.1–134.1 weeks), and the median duration of survival for the 86 evaluable patients was 9.8 months. Side effects were frequently encountered; the patients experienced anorexia, nausea, vomiting, malaise, alopecia, and leukopenia, but all of these symptoms were tolerable.
