Methodology Retrospective study of 28 premenopausal women with endometrial cancer, treated at the Carcinological Radiotherapy department, FarhatHached Hospital, Tunisia, between 1995 and 2020.

Results The median age was 48 [16–51]. A family history of endometrial cancer was found in 2 patients. At the time of diagnosis, 12 patients were childless (42.9%) and 4 had primary infertility (14.3%). Diabetes and high blood pressure were found in 21,4% and 17,9% of cases, respectively. Twelve patients were overweight (42,9%).

The median patient-delay was 7.5 months [2–24]. Main circumstances of discovery were metrorrhagia and pelvis pain in 71.4% and 17.8% of cases, respectively.

The majority of patients (89.3%) underwent total hysterectomy with bilateral adnexectomy. Pelvic lymph node dissection was performed in 13 cases (52%). Histological analysis showed endometrioid adenocarcinoma, sarcoma and Müllerian tumor in 71,4%, 14,3% and 14,3% of patients, respectively.

According to the FIGO-2018, stage distribution was as follows : 9 cases (32,1%) in stage I, 9 in stage II, 5 (17,9%) in stage III and 5 cases in stage IV.
