Popis: Endometrial cancer ranks the third place in prevalence among all cancers in Ukraine. The surgicaltreatment and subsequent adjuvant treatment is planned according to the patient's risk group. The choice of radi-ation therapy and the need to add chemotherapy determines the level of recurrence-free survival.The aim of the study was to analyze the database of treated patients in National Cancer Institute, with Istage endometrial cancer intermediate and high-intermediate group; determination of the most frequent choice ofradiation treatment in accordance with the risk group of patients with a hysterectomy with salpingo-oophorectomyfor further observation and evaluation of diseasefree survival.Retrospective was analysed 245 patients with high and intermediate risk groups with stageI endometrial cancer. The exclusion criteria were: low-risk patients, stages II-IV and non-endometrioid histologi-cal variant.According to the analysis, there were 122/245 (49.8 %) patients of high risk group, 123/245 (50.2 %) ofintermediate risk group. High-risk patients underwent external beam therapy and brychytherapy, supplemented bychemotherapy in 5.8 % of cases (7 patients), brachytherapy with external beam therapy was performed in 58.2 % ofcases (71 patients), brachytherapy - in 8.1 % of cases (10 patients), external beam therapy was performed in 27.9 %cases. Intermediate and high-intermediate risk patients were distributed as follows: brachytherapy was performedin 41.5 % of cases (51 patients), brachytherapy with external beam therapy - 54.5 % (67 patients), external beamtherapy was performed in 5 patients.Brachytherapy is available for patients with intermediate risk endometrial cancer and external beamtherapy with possible addition of brachytherapy is recommended for high-intermediate and high-risk groups, espe-cially in patients with lymphatic vascular involvement. All patients are monitored for further assessment of recur-rence-free survival.Vstup. Rak endometriia zaĭmaie tretie mistse za rozpovsiudzhenistiu sered vsikh onkologichnykh zakhvoriuvan' v Uk-raïni.
