title: The role of external irradiation in the treatment of transitional cell carcinoma of the bladder-a review of fifty cases.
abstract: Of 100 patients with carcinoma of the bladder seen in the Section of Therapeutic Radiology, University of California, San Francisco, between 1957 and 1962, 59 were accepted for radiation treatment. Fifty had transitional cell carcinoma and were treated with supervolt therapy (1 mev or cobalt-60).TWO TYPES OF TUMORS WERE AGAIN FOUND SUITABLE FOR EXTERNAL IRRADIATION: Papillary carcinomas Grades II and III, as long as they have not, or at least have not massively, invaded muscle; and undifferentiated carcinomas, Grade IV, regardless of degree of extension through the pelvis. The former type, if single, is treated by irradiation for the first recurrence after one attempt with radical transurethral resection. In the presence of multiple lesions at the first examination, radiation therapy is given immediately. The latter type is treated by radiation therapy without any attempt at surgical removal.Of 37 patients, Stages A to C, treated more than three years ago, 14 (38 per cent) lived more than three years and eight (22 per cent) had no cystoscopic or clinical signs of active disease and had normal bladder function. Of 23 patients treated more than five years ago, eight were alive after five years (35 per cent) and four (17 per cent) remained controlled by radiation therapy alone, with normal bladder function.No major complications were observed. In particular, no fibrosis of the bladder occurred. Doses ranged from 5,000 r in five and a half weeks to 6,000 r in seven weeks.A close cooperation between urologic surgeons and radiotherapists during recent years permits long-range treatment planning from the time of diagnosis, which is essential in the effective therapy of carcinoma of the bladder.
