Treatment by internal iliac arterial infusion chemotherapy (IA) combined with pelvic irradiation has proved to be effective for locally invasive bladder. Eight male patients, median age of 78 years (range 73-81) were enrolled. Pretreatment CT and whole layer core biopsy revealed T3a or T3b. Pelvic CT or fine needle aspiration biopsy following bipedal lymphography revealed N0 in 4 cases, N2 in 2 and N3 in 2, respectively. Three to 7 cycles of cisplatin (CDDP) 30-50 mg/m2, methotrexate 20 mg/m2 and tetrahydropymnyl-adriamycin 20 mg/m2 every 3 week was administered combined with 40-50 Gy. of whole pelvis irradiation. In 4 renal function impaired patients, 100 mg/m2 of carboplatin was administered instead of CDDP. All patients obtained complete response and the bladders were preserved. Observation periods were from 9 to 75 months (median 37 months). One N2 patient died with metastatic disease and two died without carcinoma. Two patients developed invasive bladder cancer on the side opposite to the primary tumors. Both were successfully treated by IA and irradiation. Bladders of all except one patient functioned for a long period. Side effects of IA and irradiation were not significant. IA combined with pelvic irradiation is effective and safe for elderly patients with bladder carcinoma.
