title: [Epirubicin--results in breast cancer].
abstract: Patients with metastasized breast cancer are incurable. Remissions with longer survival can be induced by chemotherapy in 50 to 80%, with 10 to 20% complete remissions, however, recurrence is unavoidable. Therefore the strategy of therapy in breast cancer must include two aspects: first prolongation of overall survival by multiple remissions with regimes that are not cross-resistant and secondly conservation of quality of life by minimization of therapy conditioned side-effects. Epirubicin, the new anthracycline derivate and analogue of doxorubicin (probably the most active chemotherapeutic agent against breast cancer) exhibits the same high activity but lower side-effects compared with the parent compound. Complete and partial remissions in 33% of 313 breast cancer patients could be achieved with epirubicin. In three other studies the efficacy and side-effects of epirubicin were compared with the established drug doxorubicin. The remission rate was nearly the same but the side-effects such as nausea, vomiting, stomatitis, bone marrow toxicity and congestive heart failure were lower. Five different studies with epirubicin in combination with other cytostatics have shown comparable results as adriamycin combinations. In a randomized multicenter study, 520 patients were treated with epirubicin or doxorubicin in combination with cyclophosphamide and fluorouracil. The remission rates were 52 vs. 54%, respectively, but the toxicity of the epirubicin combination group was significantly lower.
