Objectives: We aimed to investigate the clinical and pathological factors of our patients who were diagnosed with endometrial cancer in terms of prognosis. With this study, we present our 10 years of surgical experience in endometrial carcinoma cases. Material and methods: Four hundred twelve patients with endometrial carcinoma who applied to our center between 2010–2019 and that we followed up were evaluated retrospectively. Results: Most of the tumors were low-grade endometrioid malignancies. Non-endometrioid types accounted for 12.1% of cases. Lymph node dissection was performed in 395 of 412 patients (95.9%). 66 (16.01%) of the 412 patients died during the follow-up period in the study sample. Higher OS and DFS rates were associated with endometrioid histological types, FIGO stage, absence of lymphovascular space invasion, lower grade and less than 50% myometrial invasion (p < 0.05). 5-year OS at stage 1, 2, 3, 4 was found as 88.9 ± 2.2%, 65.5 ± 10.8%, 49.4 ± 0.79% and 23.7 ± 0.97% respectively. 5-year DFS at stage 1, 2, 3, 4 was found as 84.1 ± 2.6%, 65.5 ± 10.8%, 47.7 ± 0.78% and 23.7 ± 0.97% respectively. In univariate analysis, Age, tumor histology, FIGO stage, histological grade, LVSI, positive peritoneal cytology, cervical involvement, myometrial invasion and not receiving adjuvant therapy were defined as prognostic factors. Conclusions: Age, grade, FIGO stage, myometrial invasion, histological type, LVSI involvement, cervical involvemet, positive peritoneal cytology and not receiving adjuvant therapy are important prognostic factors for progression-free survival and overall survival in patients diagnosed with endometrial cancer
