摘要: PURPOSE: To determine the frequency of developing abnormal pathologic changes in endometria tamoxifen-treated women. characterize type involved. PATIENTS AND METHODS: Between October 1991 and September 1998, 159 patients initiating tamoxifen therapy for breast cancer confined to axillary lymph nodes were entered a prospective study. In this study, office endometrial biopsies (EMBs) obtained during initiation at 6-month intervals 2-year period. Three subsequent annual EMBs recorded each patient, amounting 5-year surveillance. RESULTS: One hundred fifty-nine with median age 50 years onto Patients assessable if performed least 1 year after treatment. Nine (5.7%) considered protocol violations. The remaining 111 underwent total 635 (mean, 5.8 EMBs), surveillance time 36 mo...
