Mutations over several driver genes, such as epidermal growth factor receptor (EGFR), echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) fusion mutations, Kirsten rat sarcoma viral oncogene homolog, and human EGFR 2, are known to be involved in the initiation and maintenance of lung adenocarcinoma (3). This evidence concerns the gene EGFR and lung adenocarcinoma.
