Purpose: To carry out a quantitative assessment of the quality of planning the remote radiotherapy component of patients with uterine body cancer for three different radiotherapy technologies: 3D conformal radiation therapy 3D-CRT, radiation therapy with intensity modulation IMRT, and with intensity modulation in the rotational mode RapidArc. To determine radiation exposure to critical organs.Material and methods: Radiotherapy plans for 102 patients were calculated using the Eclipse (Varian) planning system. Plans were evaluated using homogeneity and conformity indices from dose-volume histograms. When analyzing dose loads on the rectum, bladder and pelvic bones, a differential dose-volume characteristic was used, which reflects the modal dose D dif . Radiotherapy was carried out on accelerators of the ClinaciX (Varian) model with a photon of 6 MV.Results and conclusion: It turned out that 3D-CRT and IMRT are the most favorable methods for the remote component of radiotherapy. The smallest value of the modal dose D dif for the rectum is achieved with the RapidArc method and is 41 ± 10 Gy. The smallest value of the modal dose D dif for the bladder is also achieved with the RapidArc method and is 45 ± 9 Gy. The dose loads on the femoral heads are approximately the same for all three irradiation methods.
