Targeting ErbB2 aberrations in non-small cell lung cancer %K %X Human epidermal growth factor 2 ( HER2 or ErbB2 ) mutations in lung cancer are oncogenic drivers similar to epidermal growth factor receptor ( EGFR ) mutations in non-small cell lung cancers. Until recently, ErbB2 -mutant lung cancers have generally been resistant to various targeted agents. However, a new wave of ErbB2 -targeting drugs has shown promise for this subset. We highlight a case of a patient with an ErbB2 -mutant lung cancer with an exon 20 YVMA insertion who had a good response to poziotinib and review the current literature on the methods of testing for ErbB2 mutations and the efficacy of various known and emerging targeted agents. %U https://pcm.amegroups.org/article/view/5169 %V 2 %P %@ 2617-2216
