Hyperthermic intravesical peplomycin perfusion treatment for bladder cancer.

Abstract

Thirty-three patients with malignant bladder tumours were treated by hyperthermic intravesical perfusion. The study group included 25 patients with superficial T1 bladder tumours, 4 with T2 tumours and 4 with T3 tumours. Physiological saline solution containing 40 micrograms/ml peplomycin with/without 2% ethanol was used as a perfusate. Perfusion was carried out for 2 h 3 times per week and this regimen was repeated every other week, totalling 6 sessions in 3 weeks. Three patients achieved a complete response (CR), 5 a partial response (PR) (more than 50% tumour reduction), 8 a minimal response (MR) (25-50% tumour reduction) and the remaining 17 patients showed no response (NC). Complete, partial and minimal responses were obtained only in patients with T1 tumours. The NC patients included 4 with T2 and 4 with T3 lesions. Profuse haematuria from invasive tumour was markedly reduced after treatment. A major side effect was irritation of the bladder and urethra. Our results indicate that hyperthermic perfusion with ethanol and peplomycin is clinically safe, is accompanied by very little pain and may be useful for the management of superficial bladder tumours in elderly patients.
