Summary
In recent years, the incidence of endometrial carcinoma (EC) has increased significantly and patients tends to be younger. In addition to known risk factors such as obesity, hypertension and diabetes, genetic factors also play an important role in the occurrence and development of EC. Among them, Mismatch Repair Defect (MMR) can produce mutant phenotypes, leading to cancer susceptibility. Although some articles indicated that epigenetic MMRd, one type of MMRd, predicted poor prognosis among endometrial carcinoma patients, hitherto, the clinicopathological significance and prognosis of epigenetic MMRd has not been determined. To date, there are no relevant large-sample data to investigate the prevalence of epigenetic MMRd in Chinese population, as well as the impact on the prognosis of endometrial cancer. In this setting, The purpose of this study was to investigate the prevalence of epigenetic MMRd and its impact on clinicopathology and prognosis on endometrial cancer among Chinese patients.
