Анотация: The purpose of this study was to assess the influence of the constitutional features of uterine cancer patients on the difference between the planned and actual dose received on the rectal mucosa. The intention also was to identify how the planning of radiation therapy in this group of patients is complicated by anatomical features of the pelvic organs. Particularly, when dense tissues and hollow organs combine in a limited range, this can affect device displacements and errors in dose calculations for healthy organs. This study examined 110 patients, and in vivo dosimetry was performed for them to determine the dose load on the rectal mucosa. This allowed determining a pattern of deviation between the planned dose and the results of in vivo dosimetry depending on constitutional data. Among all the factors considered, only body weight and body mass index at the tenth irradiation session demonstrate a probable effect in patients who underwent irradiation on the Clinac 600 C linear accelerator. The study ascertained no probable dependence of the influence of constitutional features in patients irradiated on the ROCUS-AM apparatus. The data obtained during the study indicate the need to develop innovative approaches to topometric preparation of overweight genital cancer patients, and for further dosimetric control in this category of patients.
