Title: A Phase III Trial Evaluating The Role Of Exemestane Plus GnRH Analogue As Adjuvant Therapy For Premenopausal Women With Endocrine Responsive Breast Cancer
Brief Summary: RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using triptorelin, exemestane, and tamoxifen may fight breast cancer by blocking the use of estrogen. It is not yet known whether giving triptorelin together with exemestane is more effective than triptorelin and tamoxifen in treating hormone-responsive breast cancer.

PURPOSE: This randomized phase III trial is studying triptorelin and exemestane to see how well they work compared to triptorelin and tamoxifen in treating premenopausal women with hormone-responsive breast cancer.
