FEATURES OF BRACHYTHERAPY OF SECONDARY VAGINAL CANCER WITH DUE REGARD FOR RADIOBIOLOGICAL ASPECTS
Technologies of high-energy modern brachytherapy with high-dose rate (HDR) sources of <sup>192</sup>Ir and <sup>60</sup>Co of higher than 12 Gy make it possible within a short time interval to concentrate high doses of energy of ionizing radiation in a limited volume of tissues with minimal risks of severe radiation reactions or damage. Purpose. The search for optimal models of contact radiation therapy aimed to increase the effectiveness of chemoradiotherapy of secondary vaginal cancer (metastatic forms) continues to be the subject of extensive discussion.
