Abstract

This review evaluates tolerance and disease control for eight patients with muscle invasive bladder cancer treated with pelvic radiotherapy and concomitant paclitaxel/carboplatin chemotherapy. From October 1996 through February 1998, eight patients were treated with pelvic radiotherapy and concomitant paclitaxel/carboplatin chemotherapy. All received from 39.60-41.40 Gy to the pelvis followed by a boost to the initial site of disease. Final tumor doses ranged from 64.80-68.40 Gy. Most patients received paclitaxel at 150 mg/m2 and carboplatin at an area under the curve (AUC) of 7 at 3-week cycles during the radiation therapy. No patient required treatment interruption. With a median follow-up of 27 months, three patients remain free of local and distant disease at follow-up intervals of 24, 25, and 31 months. No surviving locally controlled patient demonstrated late urinary or gastrointestinal morbidity. All patients with a visibly complete transurethral resection of bladder tumor (TURBT) prior to radiotherapy achieved local disease control. For this group of patients, the absolute 2-year pelvic tumor control rate is 57%. The 2-year disease-specific survival is 43%. Paclitaxel/carboplatin chemotherapy can be delivered with continuous course pelvic radiation therapy without severe acute or apparent late toxicity. This combination also appears to be effective in achieving disease control in the urinary bladder, particularly in those patients who have undergone a thorough TURBT. The authors believe that it would be reasonable to investigate this combination in future bladder conservation protocols. The combination of paclitaxel and carboplatin with radiotherapy may be of particular value in elderly patients or those with renal impairment.
