Abstract

BACKGROUND. Endometrial polyps are the most common endometrial pathology described in association with postmenopausal tamoxifen exposure. Up to 3% of these polyps may show malignant changes. However, to the authors' knowledge no one has described any risk factor for the development of this pathology in postmenopausal patients with breast carcinoma treated with tamoxifen. OBJECTIVE. The objective of this study was to evaluate whether risk factors can be identified for the development of endometrial polyps in postmenopausal patients with breast carcinoma treated with tamoxifen. METHODS. The authors reviewed the medical records of 54 postmenopausal patients with breast carcinoma in whom endometrial polyps were resected by hysteroscopy after at least 6 months of tamoxifen treatment (Group I). Demographic characteristics, health habits, risk factors for endometrial carcinoma, and clinical factors related to the primary breast disease were examined. The results were compared with those obtained from 210 similar patients in whom hysteroscopy did not reveal any endometrial pathology (Group II). RESULTS. Age at menopause was significantly older, duration of breast disease was significantly longer, and body weight was significantly heavier among Group I patients compared with Group II patients (P = 0.0162, P = 0.0026, and P = 0.0364, respectively). Endometrial thickness, measured by transvaginal ultrasonography, was significantly thicker in Group I patients (16.3 ± 7.2 mm) compared with that detected in Group II patients (11.8 ± 6.3; P = 0.0001). CONCLUSIONS. Various factors, such as older age at menopause, longer duration of breast disease, heavier weight, and thicker endometrium may contribute to the prediction of increased risk of development of endometrial polyps in postmenopausal patients with breast carcinoma treated with tamoxifen.
