title: Postdiversion precystectomy irradiation for cancer of the bladder.
abstract: This is the first report of a 4-year prospective trial of integrated irradiation and cystectomy in the management of advanced bladder carcinoma. Patients are treated sequentially with staging laparotomy and urinary diversion, highdose preoperative irradiation (5,000 rad/30 treatments/42 days), and total cystectomy. Twenty-eight consecutive patients have been entered into the study; all had Grade III or IV tumor or clinical evidence of invasion (Jewett Stage B1-D1). Local control has been achieved in 21 of 22 patients, and the 4-year actuarial survival is 54%. The initial staging procedure not only defines inoperable patients, but also allows completion of urinary diversion prior to small bowel irradiation with fewer anastomotic problems. Acute and chronic complications have been minimal, and there have been no treatment-related deaths.
