Ultrasound fi nding of endometrial polyp and factors increasing risk of malignancy

Abstract

This article presents a comprehensive review of factors that increase the risk of malignancy in ultrasound findings of an endometrial polyp. We collected original studies, reviews, and meta-analyses that dealt with the endometrial polyps topic and the risk of developing endometrial cancer. Each presumed risk factor was analyzed individually. According to searched studies, abnormal uterine bleeding, old age, and BMI are valid risk factors for developing endometrial cancer in endometrial polyps. Lynch syndrome patients are also in a high-risk group for endometrial cancer. On the other hand, the number of polyps, their size, diabetes mellitus, hypertension, and positive family history are factors with inconclusive results. There are either not enough data or different results among several studies.
