title: [Meta analysis of the association between the expression of microRNA-155 and the outcome of patients with lung cancer].
abstract: OBJECTIVE
  To evaluate the association between the expression of microRNA-155 (miRNA-155) and the outcome of patients with lung cancer systemically.
  
  
  METHODS
  7 case-control studies about the expression of microRNA-155 that were based on our inclusion criterion and available in the literature were reviewed from CBM disc, CNKI, VIP, Wanfang data SCIRUS, ASCO and ESMO. Meta-analysis was carried out by Stata 12.0 software.
  
  
  RESULTS
  Seven studies were included into the researches and there were no biased among the studies. After deleting the significant heterogeneity study, it showed significant association between the high expression of microRNA-155 and the outcome of patients with non-small cell lung cancer with the merged HR was 1.48 with 95% CI 1.07-2.06.
  
  
  CONCLUSIONS
  The current paper on Meta-analysis demonstrated a correlation between the high expression of miRNA-155 and the outcome of patients with non-small cell lung cancer.
