M-VAC or MVC for the treatment of advanced transitional cell carcinoma: metastatic, induction, and adjuvant.
The cisplatin-based combination chemotherapy regimens of M-VAC (methotrexate, vinblastine, doxorubicin, cisplatin) or MVC (methotrexate, vincristine, cisplatin) were given to 25 patients with metastatic urothelial carcinoma, 13 with locally advanced bladder cancer, and 10 as adjuvant therapy after radical surgery. Toxicity was significant with two deaths. Forty-eight percent of the patients with metastatic disease had a complete (20%) or partial (28%) response. Survival was only improved if a CR was achieved. Nine of 13 patients given M-VAC/MVC as neoadjuvant therapy underwent cystectomy and six are free of disease (mean 31 months). Three of the four patients who did not have radical surgery are also free of disease. These regimens appear to be superior to cisplatin alone. In the overall response evaluation, however, toxicity is greater.
