Finally, a total of 14 relevant studies were included. Statistical methods were used to analyze the data, including calculation of standard deviation and 95% confidence interval, and for analysis, the fixed effects model was utilized. </span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Results: </span></span></span></span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">Meta-analysis of untreated and healthy groups showed that serum c-Myc mRNA expression in untreated group is remarkably superior to healthy group (standard deviation -1.64, 95% confidence interval -1.85 to -1.45, P<0.001). In addition, serum c-Myc mRNA expression levels in elderly sufferers with NSCLC are remarkably superior to younger group (standard deviation 1.45, 95% confidence interval 1.15 to 1.74, P<0.001). In addition, serum c-Myc mRNA expression in the non-smoking group is remarkably superior to smoking group (OR=-1.78, 95% CI -1.95 to -1.60, P<0.001). </span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Conclusions: </span></span></span></span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">Serum c-Myc mRNA expression levels in elderly NSCLC suffers are superior to healthy groups, which were related to age and smoking behavior. This finding is significant for the early screening, diagnosis and prognosis assessment of NSCLC, providing a basis for further research on the role of c-Myc gene in elderly NSCLC.</span></span></span></span></span></span></span></span></span></div> C-Myc gene expression, non-small cell lung cancer, chemoradiotherapy, meta-analysis. 481 487 http://ijrr.com/browse.php?a_code=A-10-1-1354&slc_lang=en&sid=1 Z.L.
