Adjuvant chemotherapy for invasive bladder cancer.

From June 1982 through December 1985, 25 patients who had undergone radical cystectomy with pelvic node dissection for pathologic stage-pT3 or -pT4 and/or N+ disease received adjuvant chemotherapy involving the injection of cis-platinum alone or in combination with adriamycin and 5-fluorouracil (CAF). Thirteen patients also received preoperative adjuvant chemotherapy involving the infusion of cis-platinum, adriamycin, and mitomycin C into the bilateral internal iliac arteries. Postoperative adjuvant chemotherapy was performed using the following two protocols. Protocol 1 (18 cases) consisted of cis-platinum alone being administered every week for 3 weeks and then every month for 1 year. In protocol 2 (7 cases), cisplatinum, adriamycin, and 5-fluorouracil were administered at 3-week intervals on three occasions and then every month for 1 year. Eighteen patients were still alive with no evidence of disease after an average of 26 months. One patient died as a result of factors unrelated to cancer. Local recurrence and distant metastasis occurred in 6 patients, of whom 3 were still alive for an average of 20.7 months. Three patients died of cancer progression after 9, 19, and 21 months. The survival rate for all 25 patients at 50 months was 77%. Nausea and vomiting occurred in most patients during the administration of cis-platinum. Mild myelosuppression developed in a few patients subjected to protocol 2. Our results indicate that adjuvant chemotherapy consisting of the administration of cis-platinum alone or in combination with other chemotherapeutic agents appears to be effective in patients with invasive bladder cancer.
