Radiation therapy of cancer of the urinary bladder
2000 rad rotational therapy with reduced field to the prostate in 35 fractions over 7 weeks. All fields were treated at each session. Local control rates were 100% for stage A, 95% for stage B, and 83% for stage C. The disease free survival rate was 63% for all stages. Sexual potency was maintained at 80% and morbidity was minimal.

RADIATION THERAPY OF CANCER OF THE URINARY BLADDER Dr. Narayan Kalavathi and Dr. Philip Littman Department of Radiotherapy, Hospital of the University of Pennsylvania, 34th & Spruce Streets, Philadelphia, PA 19104
A retrospective analysis of 84 patients with carcinoma of the urinary bladder treated in the radiation therapy department of the Hospital of the University of Pennsylvania from 1966 through 1971 was undertaken to see if there were worthwhile long term survivals in the dose range of 6000-7000 rads in 6-7 weeks. Though accurate clinical staging was not possible in many cases, the prognosis was obviously influenced by stage, histological type and grade. These were mainly poor risk patients who had undergone partial surgical extirpation and the outlook was not very bright. Of these 84, 70 were transitional cell carcinomas; the rest being adeno, squamous, a mixture of squamous and transitional, and anaplastic or undifferentiated where cell type could In Grades I and II did better than Grades III and IV. not be determined. only ten cases was muscle invasion mentioned. Those who received 6000-7000 rads in 6-7 weeks did better than lower doses although there was tumor sterilization even at 3000 rads in one instance. Out of eight Overall, 26 out of 84 survived five years or longer (30.9%). who underwent intravesical radium partial resection, gold seed or radon seed implant - four survived five years or longer. There was only one severe late complication of post radiation sigmoid obstruction and at surgery no tumor was found. External irradiation has a definite place in the treatment of advanced bladder cancer and higher local doses achieve long term control.
