Endocrine therapy remains pivotal in the adjuvant therapy of premenopausal women with hormone receptor-positive breast cancer. Ovarian ablation, used alone, is effective in delaying recurrence and increasing survival in such women. ⋯ Adjuvant trials comparing ovarian ablation with or without tamoxifen to CMF-type chemotherapy (cyclophosphamide, methotrexate, fluorouracil) suggest that the endocrine therapy is equivalent to or better than this chemotherapy in women whose tumors express estrogen and/or progesterone receptors. Endocrine therapy with ovarian ablation, tamoxifen, or the combination is also useful in the metastatic setting in premenopausal women.
