Neoadjuvant and Adjuvant Exemestane in Treating Postmenopausal Women With Locally Advanced Hormone Receptor-Positive Breast Cancer

Summary

RATIONALE: Estrogen and progesterone can stimulate the growth of breast cancer cells. Hormone therapy using exemestane may fight breast cancer by reducing the production of estrogen and progesterone. Giving hormone therapy before surgery may shrink the tumor so it can be removed with breast-conserving surgery. Giving hormone therapy after surgery may kill any remaining tumor cells. PURPOSE: Phase II trial to study the effectiveness of neoadjuvant and adjuvant exemestane in treating postmenopausal women who have locally advancedestrogen and/or progesterone receptor-positive breast cancer.
