Summary
Endometrial polyps carry a risk of malignancy, particularly in postmenopausal women. Hysteroscopic evaluation and resection are recommended for postmenopausal women, while asymptomatic premenopausal patients with small polyps may be observed.
Area of Science:
- Gynecology
- Reproductive Medicine
- Oncology
Background:
- Endometrial polyps are common, but their pre-malignant and malignant potential requires careful assessment.
- Clinical parameters may influence the risk of malignancy within these polyps.
Purpose of the Study:
- To evaluate the pre-malignant and malignant potential of endometrial polyps.
- To identify clinical factors associated with malignancy in endometrial polyps.
Main Methods:
- Retrospective review of 430 cases with hysteroscopically diagnosed endometrial polyps.
- Analysis of medical records, preoperative vaginal sonography, and histopathology findings.
- Statistical analysis to determine associations between clinical parameters and malignancy.
Main Results:
- Hysteroscopy accurately diagnosed endometrial polyps in 95.7% of cases.
- Pre-malignant or malignant conditions were found in 3.3% and 3.0% of polyps, respectively.
- Older age, postmenopausal status, and larger polyp size (>1.5 cm) were associated with increased risk, though malignancy prediction was low. All malignant cases occurred in postmenopausal women.
Conclusions:
- Postmenopausal women with endometrial polyps have an elevated risk of malignancy.
- Hysteroscopic resection is advised for all postmenopausal women with polyps, regardless of symptoms.
- Asymptomatic premenopausal women with polyps <1.5 cm may be managed expectantly.
