Radiation therapy for transitional cell bladder carcinoma. A ten-year experience

From 1969 to 1979, 185 patients with transitional cell bladder carcinoma were curatively irradiated; 147 were treated with radiation alone (RT) and 38 received a combined radiation + surgery (RT + S). At presentation, 40 percent of the patients had obstructive uropathy which yielded a much lower five-year survival (18%) than when it was absent (50%). The overall five-year disease-free survival was 30 percent and 53 percent for patients treated with radical RT and RT + S, respectively. Among patients subjected to preoperative irradiation, downstaging was seen in 40 percent of postsurgical specimens, with 27 percent of the specimens showing no evidence of tumor; these patients had excellent survival. Severe complications were seen in 3 percent, 10 percent, and 27 percent of patients in the radical RT, RT + S, and radical RT + salvage cystectomy groups. Survival results, pelvic controls, and patterns of failure are presented.
