[Adjuvant chemotherapy (MVP-CAB; methotrexate, vincristine, cisplatinum, cyclophosphamide, adriamycin, and bleomycin) for bladder cancer].

Twenty-three patients with bladder cancer (TCC; 18 patients, SCC; 5 patients) were treated with adjuvant chemotherapy (day 1: methotrexate 20 mg/m2, vincristine 0.6 mg/m2, cyclophosphamide 500 mg/m2, adriamycin 20 mg/m2, bleomycin 30 mg, day 2: cisplatinum 50 mg/m2; MVP-CAB). A total of 3 cycles of MVP-CAB were given as preoperative or postoperative therapy. The following results were obtained. Group 1 (purpose to preserve the bladder, preoperative MVP-CAB): Four of 7 patients achieved a partial response. It was possible to perform bladder preservation surgery in 3 of these 4 patients. All 3 patients had pedunculated, solitary tumors, and there was no carcinoma in situ. Group 2 (purpose to improve the prognosis; preoperative MVP-CAB): Hydronephrosis did not resolve in the 4 patients with this complication. They received total cystectomy, and 2 patients died of cancer 23 months later. Group 3 (purpose to improve the prognosis; postoperative MVP-CAB): Ten of 12 patients (total cystectomy; 10 patients, partial cystectomy; 2 patients) survived disease-free for an average of 17 months (5-44 months), 1 patient developed recurrence 12 months later, and 1 patient died of cancer 6 months later. The 1-year survival rate in Group 3 was 86% for TCC, 100% for SCC, 80% for grade 3 TCC, and 89% for pT2 or more advanced cancer.
