Postoperative systemic adjuvant chemotherapy for bladder cancer.

Forty-six patients with bladder cancer without distant metastasis (M0) were treated by chemotherapy as an adjuvant after total cystectomy using three protocols (protocol I: adriamycin 50 mg/m2, cyclophosphamide 500 mg/m2, and cis-platinum 50 mg/m2 i.v., starting at least 2 weeks after surgery every 3 weeks for three cycles; protocol II: adriamycin 30 mg/m2 on the 1st postoperative day, cyclophosphamide 300 mg/m2 on the 1st and the 7th days; protocol III: FT-207 60 mg/m2, p.o. every day for 1 year). Average follow-up periods after surgery by protocol were 18 months for protocol I, 31 for protocol II, and 43 for protocol III. Analysis of the survival curves showed no statistically significant differences among the three groups or between a historical control group of 106 patients and the entire patient population examined in the present study. The histopathological grades recorded in the 46 patients were G1, G2, and G3 in 1, 22, and 23, respectively. However, from a study of 48 pT3 and pT4 cases, the survival rate of 10 patients receiving protocol I therapy was statistically significantly higher than those of 12 patients treated according to protocol II and of 26 historical controls, at 1 year and 2 years, respectively. Toxic effects, with gastrointestinal symptoms including nausea and vomiting and myelosuppression (including leukopenia and anemia) were more frequent with protocol I. Alopecia occurred in about 80%-90% of patients treated according to either protocol I or II. Almost all patients could tolerate adjuvant chemotherapy, and none of them died as a result of these regimens. The results recorded in this study justify the evaluation of combination adjuvant chemotherapy with adriamycin, cyclophosphamide and cis-platinum in a prospectively randomized trial.
