The key demographic and pathologic associated have not been definitively established. This meta-analysis was conducted to compare the frequency patients identify an enriched population NSCLC harboring gene. Methods Pubmed Embase databases for all on were searched up July 2014. A criteria list exclusion established screen studies. features, including smoking status, type, gender, EGFR status abstracted. Results Seventeen articles consisting 4511 cases included this meta-analysis. significant lower positive rate smokers (pooled OR = 0.40, 95% CI 0.30–0.54, P 0.05); however, because small sample size, no results regarding status. Conclusion This revealed that is highly correlated a never/light history, female type adenocarcinoma, largely mutually exclusive EGFR.
