    Abstract:
    PURPOSE: To test an innovative schedule of concurrent protracted intravenous infusion (PVI) of cisplatin (CDDP) and 5-fluorouracil (5-FU) and hyperfractionated radiotherapy (HFRT) with organ-sparing intent in bladder cancer. PATIENTS AND METHODS: Fifty-two patients (pts) were selected to receive an aggressive TURB followed by 2 MCV cycles, and HFRT with concomitant CDDP and 5-FU PVI (33 pts) or HFRT and concomitant CDDP and 5-FU PVI (20 pts). The 5-FU and CDDP doses ranged from 180 to 220 mg/sm/day and from 4 to 6 mg/sm/day, respectively. Radiotherapy was delivered as three 100 cGy fraction per day or two 150 cGy fraction per day to a total dose of 50 Gy to the pelvis and a 20 Gy boost to the bladder. RESULTS: Grade III toxicity in pts who received or not MCV was: rectal tenesmus 12/33 and 0/20, dysuria 6/33 and 4/20, leukopenia 3/33 and 0/20, thrombocytopenia 7/33 and 1/20 pts, respectively. A Grade IV toxicity was observed in 2 pts. Of the 28 evaluable patients treated with MCV, CR were observed in 23 (82%) and PR in 5 cases. Of the 18 evaluable patients treated without MCV, CR were observed in 18 cases (100%). Actually, 65% and 14% of the CR pts treated with or without HCV are alive and free of tumor. CONCLUSIONS: This bladder-sparing treatment shows an acceptable acute and late toxicity, similar to that observed with radiotherapy alone. The high CRs and bladder preservation rates observed deserve further clinical evaluation.
