Goserelin (Zoladex™) -: its role in early breast cancer in pre- and perimenopausal women

Current standard adjuvant therapies for premenopausal women with early breast cancer include ovarian ablation by surgery or irradiation, chemotherapy and tamoxifen. The value of ovarian ablation in prolonging the survival of premenopausal patients with early breast cancer was clearly established by the analyses performed by the Early Breast Cancer Trialists' Collaborative Group in 1996. More recently, the value of ovarian suppression using the luteinizing hormone releasing hormone analogue goserelin as adjuvant therapy in pre-/perimenopausal women with early breast cancer has been confirmed in a series of studies involving over 8000 patients. The results from these studies provide evidence that goserelin, alone or in combination with tamoxifen, is at least as effective as cytotoxic chemotherapy in patients with hormone receptor-positive tumours and is effective when used after adjuvant chemotherapy. The use of goserelin in the management of early breast cancer presents an option which can avoid the side-effects experienced with cytotoxic chemotherapy and may offer unique benefits to premenopausal patients. The consolidation of these emerging results should help in defining the optimal role for goserelin in pre-/perimenopausal patients with early breast cancer. (C) 2001 Cancer Research Campaign.
