title: [Trastuzumab (Herceptin) in the adjuvant treatment of HER-2-positive early breast cancer].
abstract: The prognosis of HER-2-positive breast cancer (characterized by amplification of the HER-2 oncogene and/or overexpression of HER-2 receptor) is unfavourable. Trastuzumab (Herceptin), a monoclonal antibody against HER-2 receptor can improve the outcome of HER-2-positive breast cancer. Up to now this was proven only in advanced disease. Recently five large multicentric phase III adjuvant trials gave level one evidence on the benefit of adjuvant treatment with Herceptin, concerning disease-free survival (DFS) and overall survival (OS). Herceptin has decreased the relative risk of recurrence with about 50% and that of death with nearly 30% in HER-2-positive early breast cancer. Based on these results Herceptin, together with chemotherapy, has been recently approved for the adjuvant treatment of HER-2-positive breast cancer.
