Combined pre- and postoperative adjuvant radiotherapy for bladder cancer.
Thirty-nine patients with invasive bladder cancer were treated using a new approach to adjuvant radiation therapy. All patients had histologic evidence of bladder muscle invasion on biopsy and were considered suitable for surgical resection. Low-dose preoperative radiation (500 rad) was delivered either on the day of or the day before cystectomy. In most instances, a radical cystectomy was performed and patients were then stratified according to pathologic stagings. Those patients with pathologically good prognostic indicators, Stage B1 low grade (I or II) disease, were followed up with no further treatment. Patients at high risk for local recurrence and pelvic lymph node involvement, Stages B1 high grade (III or IV), B2, and C, were given aggressive postoperative radiation (4,500 rad in five weeks). Patients with advanced disease, Stage D2, were given palliative therapy. All patients received the dose of preoperative radiation as planned. Preliminary results indicate that combined pre- and postoperative radiation in bladder cancer gives excellent local control of disease. A significant potential for improved long-term survival of patients has been observed.
