Purpose of investigation: To evaluate endometrial abnormalities by ultrasonography, hysteroscopy and biopsy in postmenopausal patients treated with tamoxifen as adjuvant therapy for breast cancer. Methods: The study was carried out on 113 patients who underwent vaginal ultrasonography, hysteroscopy and endometrial biopsy. Results: There was a significative relation between ultrasonographic and hysteroscopic features (p < 0.00l); 58 polyps were diagnosed at hysteroscopy, although 35 were not found at ultrasonography. A significant relation between ultrasonographic and histological findings was also documented (p < 0.005). A significant relation between histological findings and symptomatology was found (p < 0.05), although pathologies were also present in asymptomatic women. Conclusions: These results show that long-term tamoxifen therapy in breast cancer patients is associated with a higher incidence of uterine pathology. No significant relation has been documented between duration of treatment and grade of endometrial lesion (p > 0.05). Ultrasonography alone is useful in asymptomatic patients because it selects patients with increased endometrial thick­ness who should undergo hysteroscopy. Hysteroscopy is more accurate in detecting polyps, hyperplastic and neoplastic changes. Asymptomatic tamoxifen treated women should be evaluated as symptomatic patients.
