Background: The sensitivity of lung cancer to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) has been found to be associated with mutations in the tyrosine kinase domain of EGFR.However, not all mutations are sensitive to gefitinib.While CpG island methylation in the promoter region of the EGFR gene and transcriptional silencing are common in solid tumors, the role of EGFR gene promoter methylation in affecting resistance to TKIs in non-small cell lung cancer (NSCLC) remains unknown.In this study, we examined the relationship between EGFR gene promoter methylation and the therapeutic effect of gefitinib in NSCLC cells.
