Activity of EGFR-tyrosine kinase and ALK inhibitors for EML4–ALK-rearranged non–small– cell lung cancer harbored coexisting EGFR mutation


The EML4–ALK (echinoderm microtubule-associated protein-like 4 gene and the anaplastic lymphoma kinase gene) fusion oncogene represents a novel molecular target in a small subset of non–small–cell lung cancers (NSCLCs). The EML4–ALK fusion gene occurs generally in NSCLC without mutations in epidermal growth factor receptor (EGFR) and KRAS.
