Introduction. Lung cancer is the second most commonly diagnosed cancer and the main cause of cancer-related mortality in both men and women. Somatic activating mutations of the EGFR gene, increased gene copy number and certain clinical and pathological features have been associated with dramatic tumor responses and favorable clinical outcomes with these agents in patients with non-small-cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) have dramatically changed the prognosis of advanced non-small cell lung cancers (NSCLCs) that harbour specific EGFR activating mutations. However, the efficacy of an In non-small cell lung cancer (NSCLC), constitutively activating EGFR ( epidermal growth factor receptor) mutations occur in about 1116 of patients from the United States and Europe [13].

Nonsmall cell lung cancers (NSCLC) marked by EGFR mutations tend to develop resistance to therapeutic EGFR inhibitors, often due toEGF receptor (EGFR) is the major driver pathway of nonsmall cell lung cancer (NSCLC), especially lung adenocarcinoma (1, 2). Activating mutations of In non-small cell lung cancer (NSCLC), the identification of epidermal growth factor receptor (EGFR) mutations and the parallel development of EGFR tyrosine kinase inhibitors (TKIs) have radically changed the therapeutic management strategies. Mutation of epidermal growth factor receptor (EGFR) is a prediction marker of the response to tyrosine kinase inhibitor (TKI) drugs in non-small cell lung cancer (NSCLC) patients. Non-small cell lung cancer (NSCLC) patients with epithelial growth factor receptor (EGFR) mutations and bone metastases are oftenIn conclusion, ZA increased the antitumor effects of gefitinib on NSCLC with EGFR activating mutations and TKI resistance by regulating the cell cycle Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) have been established as the standard therapy for EGFR-sensitizing mutant advanced non-small-cell lung cancer (NSCLC). Gefitinib and erlotinib, which are epidermal growth factor receptor- ( EGFR-) specific tyrosine kinase inhibitors (TKIs), are widely used as molecularly targeted drugs for non-small-cell lung cancer (NSCLC).

Uncommon EGFR G724S mutations arise in non-small-cell lung cancer patients with acquired resistance to first-generation EGFR-TKIs.

The increasing understanding of non-small cell lung cancer ( NSCLC) biology over the last two decades has led to the identification of multiple molecular targets.Tissue biopsies remain the standard for the identification of such EGFR mutations. The discovery of mutations in the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) gene in non-small cell lung cancer (NSCLC) accelerated the research of molecular-targeted therapy by EGFR-tyrosine kinase inhibitors (TKIs), such as gefitinib and erlotinib.
