Abstract P1-02-03: Tumor-infiltrating lymphocytes but not HER2 copy number or ratio show prognostic value in trastuzumab-treated HER2-positive breast cancer
Abstract:Background: Around 15% of all breast cancers are HER2+, a subtype that prior to HER2-targeted therapy was associated with a poor prognosis. With advances in treatment the survival has dramatically improved, and previous studies suggest that the level of HER2 copies are predictive of the effect of anti-HER2 therapies. However, some patients progress despite HER2-targeted therapy and routine HER2 testing is hampered by inaccuracy to discriminate patients with therapy-resistant disease. Furthermore, tumor-infiltr… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
