Abstract: Objective To summarize the progress in treatment of non-small cell lung cancer (NSCLC) with mutations by specific tyrosine kinase inhibitors (EGFR-Tkis) that target the epidermal growth factor receptor (EGFR). Methods Targeted therapies with EGFR currently available were highlighted. The common mechanisms of EGFR-TKIs resistance were elaborated. The characteristics of drug-tolerant persister (DTP) cells and the mechanism of EGFR mutation leading to drug resistance in NSCLC were discussed. Results EGFR-targeted therapies could cause drug-resistance or drug-resistant cells, ultimately leading to tumor recurrence. Conclusion Insights into drug tolerance and underlying causes of resistance can help improve the effectiveness of cancer treatment.

Key words: non-small cell lung cancer(NSCLC), epidermal growth factor receptor(EGFR), targeted therapy, tyrosine kinase inhibitors(EGFR-Tkis), drug tolerance, acquired drug resistance
