Abstract

Luteinising hormone releasing hormone agonists (LH-RHa) induce ovarian suppression in premenopausal women that is usually reversible on cessation of therapy. They act by binding to pituitary LH-RH receptors, resulting in down regulation of receptors and subsequent suppression of luteinising hormone and estradiol. LH-RHa are effective in the treatment of advanced breast cancer in premenopausal women but their role as adjuvant treatment of early breast cancer is still controversial. Approximately 60% of tumors in premenopausal women are hormone sensitive and these patients are candidates for hormonal treatment. Tamoxifen for 5. years is considered the standard endocrine therapy for all premenopausal women with hormone sensitive breast cancer. There is no definitive evidence of additional benefit associated with the use of LH-RHa administered as an alternative or in addition to tamoxifene. In this review we discuss available data on the role of LH-RHa alone or in combination with tamoxifen; on the role of LH-RHa in combination with aromatase inhibitors; and on the potential role of LH-RHa as a strategy to preserve ovarian function during adjuvant chemotherapy.
