Epidermal growth factor receptor (EGFR), a transmembrane protein with tyrosine kinase activity, is one of the most well-documented and investigated pathways in NSCLC (7), and has been identified as an oncogenic driver, playing an important role in regulating the proliferation, survival, and differentiation of tumor cells (7, 8). This evidence concerns the gene EGFR and non-small cell lung carcinoma.
