[Results of percutaneous radiotherapy of bladder cancer using 1 and 2 series of irradiation].

Abstract

In a randomized prospective clinical study, the authors investigate the results of percutaneous radiotherapy (telecobalt) with two rhythms of fractionation in patients with vesical carcinomas. A one-series irradiation with 1.5 Gy daily (except the weekends) up to a total dose of 60 Gy is compared to a two-series irradiation (in the first series 3 Gy three days per week up to 30 Gy, then irradiation-free interval of four weeks, in the second series 1.5 Gy daily up to a total focal dose of 60 Gy). The five-year survival rates are 52% after one-series irradiation and 39% after two-series irradiation. The surgical treatment consisted in a most radical resection of the vesical tumor by TUTUR, partial resection of the wall, of transvesical tumor resection.
