title: Intra-arterial infusion therapy following alteration of pelvic blood flow and concurrent radiation therapy for invasive bladder cancer.
abstract: Intra-arterial infusion therapy following alteration of pelvic blood flow and concurrent radiation therapy was performed in 13 patients with muscle invading bladder cancer (T2, 2; T3, 6; T4, 5). The internal iliac artery of the opposite side was embolized and the ipsilateral gluteal and obturator arteries were embolized by metallic coils. A catheter was placed in the ipsilateral internal iliac artery. CDDP was administered daily at a dose of 7-9 mg/body over 1 minute. Radiation was done by Microtron using 10 MV x-ray. Total dose was 4500-7060 cGy. Evaluation was done by cystoscopy, radiography and biopsy. Eight patients achieved complete response (CR) histologically. Others had partial response (PR). All CR patients had no recurrence. The observation period was between 3 and 29 months, with a mean of 11 months. This treatment modality is effective for locally advanced bladder cancer.
