The most common genetic alterations observed in non-small cell lung cancer (NSCLC) occur in the epidermal growth factor receptor (EGFR) gene, a member of the HER family (Human Epidermal Growth Factor Receptor) of transmembrane receptor tyrosine kinases (RTKs), and in KRAS - a member of the Ras family of small GTPases, which also includes HRAS and NRAS [1]. This evidence concerns the gene NRAS and non-small cell lung carcinoma.
