Between 1976 and 1983, 70 patients who underwent cystectomy for transitional cell carcinoma (TCC) of the bladder were retrospectively divided into two groups: 39 patients were treated by a protocol using 2,000 rad of radiation over a period of 5 days followed by immediate cystectomy (group 1); 31 patients who failed to be cured by definitive radiotherapy of 6,000 rad were treated by salvage cystectomy (group 2). The 5-year disease-specific survival rate was not significantly different in the two groups of patients (64.5 and 65.5%). The postoperative early complication rates were similar as well (36.8% in group 1 and 35.5% in group 2). One patient of the group treated with 2,000 rad died 19 days after surgery, giving an operative mortality of 1.4%. We conclude that there is a continuing role for salvage cystectomy after irradiation failure. One-stage salvage cystectomy has a relatively low morbidity and should be performed early after failure of definitive irradiation.
