Post-diversion pre-cystectomy irradiation for carcinoma of the bladder.

In 47 patients treated sequentially with urinary diversion and laparotomy staging, irradiation therapy and total cystectomy for invasive carcinoma of the bladder, the mortality rate was 2 per cent and the complication rate was 20 per cent. The survival rate was most favorable in patients in whom the pathologic specimen revealed no tumor after irradiation. The lower mortality and morbidity rates are attributed to staging of surgical procedures and the challenge remains to increase the number of patients in whom carcinoma of the bladder is converted by irradiation therapy to a lower stage or no tumor.
