[Intra-operative radiotherapy with excision of urinary bladder carcinoma]

From June, 1979 through Oct., 1986 forty patients (32 males and 8 females) with cancer of the urinary bladder have been treated by intraoperative radiotherapy (IORT) after surgical excision of their tumors. The five-year survival rate, by the Kaplan-Meier Method, was 100% in Grade I patients (n = 6), 56% in Grade II (n = 19), 49% in Grade III and 58% in all patients, respectively. Similarly, it was 62% for 33 patients in stages T1 and T2 of the disease and 42% for 7 patients graded T3 and T4 of only three patients out of eleven lost in this series, their deaths caused by urinary bladder cancer. IORT with a surgical excision of their bladder tumor provided excellent results in the control of recurrence.
