Prevalence, Clinicopathologic Associations, and Molecular Spectrum of <i>ERBB2</i> ( <i>HER2</i> ) Tyrosine Kinase Mutations in Lung Adenocarcinomas

HER2 mutations identify a distinct subset of lung ADCs. Given the high prevalence of lung cancer worldwide and the availability of standard and investigational therapies targeting HER2, routine clinical genotyping of lung ADC should include HER2.
