Background: The role of adjuvant EGFR tyrosine kinase inhibitors (TKIs) in resected EGFR-mutated non-small-cell lung cancer (NSCLC) remains unclear. Materials & methods: We evaluated pooled hazard ratio and 95% CI for disease-free survival, overall survival and prespecified subgroups. Results: Seven prospective studies with 1288 patients were included in the meta-analysis. Adjuvant EGFR TKIs significantly improved disease-free survival in EGFR-mutated resected NSCLC (HR: 0.41; 95% CI: 0.24-0.70) and in all subgroups. However, the overall survival benefit was not significant (HR: 0.65; 95% CI: 0.36-1.17). The benefit of adjuvant TKIs may be associated with TKI regimens, treatment duration, pathological stage and EGFR mutation type. Conclusion: Adjuvant EGFR TKIs significantly improved disease-free survival and nonsignificantly improved overall survival in resected EGFR-mutated NSCLC.
