Anastrozole and Letrozole After Surgery for the Treatment of Stage I-III Breast Cancer
NCT04294225 · Status: COMPLETED · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 161
Last updated 2025-01-28
Summary
This phase II trial studies how well anastrozole and letrozole after surgery work in treating patients with stage I-III breast cancer. Drugs, such as anastrozole and letrozole, may stop the growth of tumor cells by decreasing the amount of estrogen made by the body. Giving anastrozole and letrozole after surgery may prevent breast cancer from coming back (recurrence).
