Epidermal growth factor receptor gene is a tyrosine kinase belonging to ErbB family and along with its ligand has shown various abnormalities in NSCLC including protein overexpression, gene amplification, and mutations leading to its progression.15, 16 The anomalous activities of EGFR along with helping in tumor growth and development also regulate various cellular activities like apoptosis and angiogenesis. This evidence concerns the gene EGFR and non-small cell lung carcinoma.
