Official title
A Phase 2 Trial Of 4 Months Preoperative Letrozole 2.5 mg Daily For Postmenopausal Women With Estrogen Receptor Positive And/Or Progesterone Receptor Positive T2, T3, T4a-c, N0-2, M0 Breast Cancer- Novel Biomarkers for Aromatase Inhibitor Therapy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by reducing the production of estrogen. Giving letrozole before surgery may shrink the tumor so that it can be removed. PURPOSE: This phase II trial is studying how well neoadjuvant letrozole works in treating postmenopausal women who are undergoing surgery for estrogen-receptor positive or progesterone-receptor positive stage II, stage IIIA, or stage IIIB breast cancer.
