Abstract
Modern treatment of premenopausal breast cancer is based on well-established prognostic and predictive factors for disease outcome such as nodal status, hormone receptor expression, tumour size, tumour grading and patient age. The development of strategies according to such individual risk profiles has resulted in significant improvements both in overall and disease-free survival. An abundant number of new prognostic and predictive factors in addition to those already mentioned may help to increase our understanding of the biology of breast cancer and to individualise therapy in premenopausal patients. Although less than 10% of patients directly benefit, it is estimated that approximately each year the life of more than 4000 women in Germany will be saved or prolonged by adjuvant treatment. Whether dose intensive modifications and new antineoplastic drugs can improve disease outcome will be clarified when ongoing studies have increased observation time.
At present, hormone ablation via surgical, radiotherapeutical or drug-induced castration in addition to selective estrogen response modifiers (SERM), such as tamoxifen, with or without chemotherapy remains the cornerstone of adjuvant treatment in premenopausal patients with breast cancer. In advanced disease, new highly effective hormonal and other target-oriented antineoplastic agents with few adverse effects have been recently introduced. However, overall survival in metastatic disease remains poor, even when intensive or high-dose chemotherapy is used. Special attention must be given to longer follow up and potential toxic long-term adverse effects of therapy when new regimens are applied in clinical trials.
