Endometrial Polyp Size and the Risk of Malignancy in Asymptomatic Postmenopausal Women

Objective: The appropriate management of endometrial polyps in asymptomatic postmenopausal patients remains controversial. The aim of the study was to evaluate the relationship between endometrial polyp size and malignancy risk among asymptomatic postmenopausal women. Methods: This observational retrospective study investigated 472 postmenopausal asymptomatic women who underwent hysteroscopic polypectomy between 2010 and 2014 (Canadian Task Force Classification II-3). Results: Of the 472 women, premalignant and malignant lesions were found in 11 (2.33%) cases; four (0.84%) had endometrial carcinoma, and seven (1.49%) had atypical endometrial hyperplasia. The incidence of premalignant or malignant lesions among various cut-offs of polyp size (10, 15, 20 mm) was not significantly different. Conclusion: In the current series no significant risk factor for malignancy was found among different cut-offs of polyp size.
