[Current developments in systemic therapy of breast carcinoma].
New developments in hormone- and chemotherapy of metastasizing breast cancer comprise replacement of ovariectomy by LH-RH antagonists in premenopausal women, new antiestrogens with less residual estrogenic activity for use mainly in postmenopausal patients as well as new potent inhibitors of aromatase with fewer adverse effects also for postmenopausal women. These new drugs will possibly provide better efficacy with fewer side effects, but at higher cost. In chemotherapy the search for more potent regimes continues. Experiments are under way with high-dose chemotherapy plans in conjunction with autologous bone marrow transplantation and hemopoietic growth factors; however, the result of these latter studies are so far disappointing. It has become clear that in nonaggressive metastasizing cancer of the breast high rates of remission seem not to be the ultimate goal. At this stage of disease the natural course is very heterogeneous; therefore, chemotherapy has to be adapted to risk. The goal must be improvement of quality of life for the remaining life-span by palliation of symptomatic disease while inducing as few side effects of treatment as possible. New; more potent chemotherapeutic agents are not at sight. Research has recently produced derivatives of already known agents producing fewer adverse effects at equal efficacy. Decisive for the choice of primary chemotherapy are prognostic indicators of the disease. For most cases, tumor specific therapeutic modalities have to be optimized.
