Objectives: Endometrial carcinoma (EC), the most common gynecological malignancy, is associated with unfavorable survival in advanced stages. Treatment strategies now include cytoreductive surgery (CRS) and (neo)adjuvant chemotherapy, but survival rates remain limited. This study evaluates overall survival (OS) and surgical outcomes, including outcomes of CRS and surgical complications, over a 20-year period at the Erasmus MC. Methods: This retrospective cohort study includes women diagnosed with FIGO stage III or IV EC between 2000 and 2020 who received treatment at the Erasmus MC. Data were collected from the Netherlands Comprehensive Cancer Organization and supplemented by medical record reviews. Statistical analyses were conducted to evaluate differences in OS based on FIGO stage, histological type, molecular characteristics, CRS outcome, and type of CRS. Results: A total of 188 patients were included, with a median age of 66 years. Most patients received surgery and additional chemotherapy and radiotherapy. A total of 64 patients (59.3%) underwent primary CRS, and 44 patients (40.7%) underwent interval CRS. Patients with complete CRS had a significant survival advantage over patients with optimal and incomplete CRS (HR 0.56; 95% CI 0.33–0.96, p = 0.036). Comparison between primary and interval CRS revealed no significant difference in OS (HR 1.42; 95% CI 0.82–2.44, p = 0.207). Surgical complications occurred in 33.1% of patients, with infections most common. Two patients died from severe complications. Conclusions: This study highlights the predominant role of surgery in the management of advanced EC. Complete CRS is often achievable and offers significant survival advantage. However, approximately one-third of patients experience surgical complications.
