    Title:

    The prognostic effect of HER2 heterogeneity and YAP1 expression in HER2 positive breast cancer patients: a retrospective study

    Published date:

    Excerpt:
    Over-expression and nuclear localization of YAP1 were significant in HER2-ITH patients....HER2-NITH patients and YAP1-insufficient patients benefited from a combination of Trastuzumab and Pertuzumab/Lapatinib, while Capecitabine significantly decreased the relapse risk of ITH patients and YAP1-sufficient patients....YAP1 overexpression contributed to a poor prognostic outcome, especially when HER2 signal intensity was insufficient.
