FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to radiation therapy, and can be used for radiotherapy of prostate cancer metastases to the retroperitoneal lymph nodes. Carry out three-dimensional conformal radiation therapy in the mode of dynamic fractionation continuously in two stages. At the first stage, the entire retroperitoneal lymphocollector of the genus 2.0–2.5 Gy is irradiated daily 5 times a week for 16–22 fractions before SOD 40–44 Gy. At the second stage, the volume of radiation exposure decreases to the volume of the affected lymph nodes, and the LAM increases to 5.0 Gy daily for 4 fractions up to SOD of 20 Gy.
EFFECT: method provides locoregional control of the disease due to the observance of the oncological principle of zoning and escalation of the dose of radiotherapy to identified affected lymph nodes using three-dimensional conformal and stereotactic radiation therapy.
