Real world evidence on long-term survival of patients with endometrial cancer in Germany: Analysis of population-based cancer registry data on 49808 women.

Abstract

e17623 Background: Endometrial cancer (EC) is the most common gynecological cancer worldwide. The understanding of clinicopathological characteristics has changed within the last years. Limited data are available regarding the long-term survival of EC patients. Methods: Clinical data and survival data for patients with EC diagnosed in Germany between 2010 and 2020 were gathered from the German national center for population-based cancer registry. Differentiated by histological subtype, 5- and 7-year survival rates were calculated. Results: 49,808 patients with newly diagnosed EC between 2010 and 2020 were included in the analysis. Median age at diagnosis was 68.1 years (IQR 59.0;76.4). 5-year and 7-year overall survival was 67.5% and 56.7%, respectively, and decreased with increasing FIGO-stage: 83.7% and 72.6% for FIGO IA, 71.0% and 56.3% for FIGO IB, 59.8% and 47.3% for FIGO II, 48.2% and 38.7% for FIGO IIIA , 32.5% and 20.7% for FIGO IIIB, 40.0% and 30.6% for FIGO IIIC, 13.3% and 8.2% for FIGO IVA, 16.4% and 13.9% for FIGO IVB, respectively. Regarding histological subtype, endometrioid carcinoma showed the best 5-year and 7-year overall survival rates with 72.5% and 61.3%, respectively, followed by clear cell carcinoma with 41.2% and 34.0%, serous carcinoma with 35.5% and 24.8%, and lastly carcinosarcoma with 28.5% and 23.0%. Of 3,765 patients with known cause of death, 53.8% were due to endometrial cancer. 19.0% died of cardiovascular disease and 18.8% of other malignancies. Conclusions: Our data represents deeper insight in the characterization of long-term survival patients of this tumor entity.
