The resistance of non-small cell lung cancer (NSCLC) to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) has been brought into focus. COX-2 signal pathway was found to be closely related to EGFR signal pathway by recent researches, and there has been a growing interest to focus the researches on whether COX-2 pathway inhibition improves the efficacy of EGFR-TKIs in treating advanced NSCLC. In this review, we will illustrate recent advances of combined inhibition of EGFR and COX-2 signal pathways in NSCLC therapy.
