Epidermal growth factor receptor gene -216G/T polymorphism has been implicated to be associated with clinical outcomes in advanced non-small cell lung cancer (NSCLC) patients treated with EGFR-TKIs. However, the results are inconsistent due to the limitation of sample size. Based on previous studies; we conducted this meta-analysis aiming to provide more reliable results. A total of 6 studies, including 955 advanced NSCLC patients treated with EGFR-TKIs, were included. Review Manager 5.3 was used to perform the statistical analysis. The response rate (RR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) were included in our outcomes. Our study suggested that TT+GT genotypes showed association with higher response rates (GT+TT vs. GG RR = 2.08; 95% CI = 1.53-2.82; P<0.00001), higher disease control rate (GT+TT vs. GG RR = 1.23; 95% CI = 1.08-1.40; P = 0.002), longer progression-free survival (GT+TT vs. GG HR = 0.80; 95% CI = 0.67-0.95; P = 0.009) and longer overall survival (GT+TT vs. GG HR = 0.80; 95% CI = 0.66-0.96; P = 0.01) than GG homozygote. The combined results based on all included studies suggested that EGFR-216G/T polymorphism could be a potential biomarker for EGFR-TKIs in advanced NSCLC patients.
