title: Intra-arterial chemotherapy for bladder cancer by insertion of catheter from inferior gluteal artery.
abstract: Thirty-four patients with locally advanced bladder cancer have been treated with selective intra-arterial infusion of CDDP and/or ADM (IA therapy) prior to planned surgical resection. Follow-up ranged from 25 to 108 months (median 61). Initial tumor stage was cT2 in 10 patients, cT3 in 19 and cT4a in 5. Catheterization technique: gluteal muscles were dissected gently along the muscle fiber to expose the inferior gluteal artery with the patients in prone position, then the catheter was inserted. The tip was wedged in the internal iliac artery below the bifurcation of the superior gluteal artery. ADM 10-20 mg and/or CDDP 10-20 mg were infused once or twice a week. Total dose of ADM and CDDP were 40-580 and 60-240 mg. Thirteen patients received IA therapy + hyperthermia and 8 IA therapy + irradiation. Surgical resection included total cystectomy (22 patients), partial cystectomy (3 patients) and transurethral resection of the prostate (5 patients). Survival rate at 5 years is 57.9% (T2 = 90.0, T3 = 52.1, T4 = -). Eighteen patients are alive with no evidence of recurrences, and 11 patients were free of disease for more than 5 years. Side effects were bone marrow suppression (5 patients), vomiting (4), erosion of gluteal skin (7), and neurotoxicity, such as sensory disturbance in lower extremities or ischialgia (2); treatment was well tolerated in others. In conclusion, our results suggest that intra-arterial infusion of ADM and/or CDDP by insertion of catheter from inferior gluteal artery is safe with minimal systemic side effects, and prolongs survival for invasive bladder cancer.
