Predictors of malignancy in endometrial polyps: a multi-institutional cohort study

Area of Science:

• Gynecology
• Reproductive Medicine
• Oncology

Background:

• Endometrial polyps (EPs) pose a variable risk of malignancy (0.3%-4.8%).
• Management strategies for asymptomatic incidental EPs are not well-defined.
• Understanding risk factors is crucial for appropriate patient management.

Purpose of the Study:

• To correlate demographic and clinical factors with histopathological findings in hysteroscopically removed EPs.
• To identify predictors of malignancy in endometrial polyps.
• To inform management decisions for patients with EPs.

Main Methods:

• An observational, multi-institutional cohort study.
• Inclusion of 813 premenopausal and postmenopausal women undergoing hysteroscopic polypectomy (February 2010 - December 2012).
• Review of clinical features correlated with histopathologic results.

Main Results:

• Older age, high BMI, obesity, postmenopausal status, abnormal uterine bleeding (AUB), and hypertension correlated with malignant EPs.
• Multivariable analysis confirmed age (OR 1.08) and AUB (OR 3.53) as significant predictors.
• Incidental findings of EPs in asymptomatic women require careful consideration of risk factors.

Conclusions:

• Postmenopausal status, AUB, older age, high BMI, and hypertension identify patients at increased risk for premalignant/malignant EPs.
• Hysteroscopic removal is the recommended surgical approach for high-risk patients.
• Further research into asymptomatic incidental EPs is warranted.
