Abstract P4-01-27: Prognosis and treatment landscape of HER2-positive metastatic breast cancer (MBC) before the availability of tucatinib and trastuzumab-deruxtecan: Results from the Austrian AGMT_MBC-Registry
Abstract:Background: New anti-HER2 drugs such as tucatinib and trastuzumab deruxtecan (T-DXd) have shown to improve survival of HER2+ MBC in clinical phase III trials. To allow a future confirmation of this survival advantage in real world, we evaluated the prognosis of HER2+ MBC patients before the availability of tucatinib and T-DXd in Austria. Furthermore, we analyzed the treatment landscape and the drop-out rate between subsequent lines of therapy as documented in the MBC-Registry of the Austrian Study Group of Med… Show more
