HER2-mutant non-small cell lung cancer

HER2-mutant non-small cell lung cancer is a distinct molecular subtype of non-small cell lung cancer characterized by activating somatic mutations in the *ERBB2* (HER2) gene

HER2-mutant non-small cell lung cancer is a distinct molecular subtype of non-small cell lung cancer characterized by activating somatic mutations in the *ERBB2* (HER2) gene Pathophysiologically, these genetic alterations—most frequently in-frame insertions within exon 20 of the kinase domain—lead to constitutive, ligand-independent activation of HER2 receptor tyrosine kinase signaling, driving downstream oncogenic pathways that promote uncontrolled cellular proliferation, survival, and disease ...

Primarily arising in lung adenocarcinomas, this malignancy disproportionately affects non-smokers and female patients, representing roughly two to four percent of all non-small cell lung cancer cases
