[Radiation treatment of bladder cancer using different fractionation regimens].

The paper is devoted to a follow-up of 177 bladder cancer patients. The problems of providing radiotherapy with the use of hyperfractionation of a radiation dose were discussed. Despite an increase in a tumor dose by 15%, no increase in the number and expression of local radiation reactions is observed. Enhanced therapeutic efficacy was observed, particularly in cases of locally advanced tumors (T3). Three years after conventional radiotherapy 44% of the patients were alive, after hyperfractionated irradiation--69%.
