Multicenter StudyEndometrial histopathology in 700 patients treated with tamoxifen for breast cancer.
The aim of this study was the evaluation of endometrial histopathologic findings from 700 patients treated with tamoxifen (Tx) for breast cancer from two medical centers (United States and France). ⋯ Most Tx-treated patients had no pathologic endometrial changes. Endometrial polyps, hyperplasia, and metaplasia, consistent with an estrogen-agonist effect of Tx, were found in roughly one-third of all patients. The endometrial cancers were often high-grade and invasive tumors. Patients with endometrial pathology were more often symptomatic than patients with inactive/atrophic endometria.
