RADIO BIOLOGICAL JUSTIFICATION AND BEAM REACTIONS AT THECOMBINED RADIATION THERAPY OF THE PROSTATE CANCER
In work radiobiology, justification is carried out and beam reactions at the combined radiation therapy of a prostate cancer are studied. It is established that increase in biologically effective dose by data linearly - square model of cellular survival from 203,4±1,0 Gr to 250,5±0,6 Gr is not enough for significant growth of frequency of biochemical control at the combined radiation therapy of a prostate cancer. With increase in a dose of brachytherapy from 8,5 the frequency of acute beam reactions of 1-2 degrees from an urinary system and intestines increases up to 10,5 Gr at the combined radiation therapy.
