[Intra-arterial cisplatin and concurrent radiation for invasive bladder cancer].
Fifteen patients with invasive bladder cancer were treated with selective intra-arterial cisplatin and external beam radiotherapy (30.6 Gy over 3 weeks) prior to a planned cystectomy. Cisplatin, in total 200 mg, was administered via bilateral internal iliac artery infusion during the course of radiotherapy. Seven patients were evaluated for local response. Partial response (PR) was revealed in 4, and minor response (MR) in 3. Ten patients received total cystectomy, and pathological effects by the criteria adipted by Japanese Urological Association and The Japanese Society of Pathology, were as follows: Ef. 3 in 1 case, Ef. 2 in 6. Ef. 1b in 1 and Ef. 1a in 2. Down staging was observed in 8 patients from the clinical to the pathological stage. Thirteen patients are alive for 21 months. Two patients have died (1 lung infarction, 1 pancreatic cancer). Though nausea and sciatica-like pain were observed in some cases, there was no severe systemic side effects such as bone marrow suppression and renal toxicity. From these results it is concluded that this therapeutic modality could be effective in the preoperative work-up of candidates for total cystectomy, and also that it could be useful in the treatment of patients in whom total cystectomy is contraindicated.
