Current evidence suggests that the neutrophil-to-lymphocyte ratio (NLR) may be a biomarker for poor prognosis in lung cancer, although this association remains controversial. Therefore, a meta-analysis was performed to evaluate the association between NLR and lung cancer outcome. A systematic literature search was performed through the PubMed, Embase and Cochrane Library databases (until July 30, 2016), to identify studies evaluating the association between NLR and overall survival (OS) and/or progression-free survival (PFS) among patients with lung cancer...

Accumulating papers have demonstrated that microRNAs play an important role in the progression of lung cancer, mainly as oncogenic and tumor suppressive. Therefore, microRNAs may influence the survival of lung cancer patients. In this meta-analysis, we evaluated the role of microRNAs in affecting the overall survival in nonsmall cell lung cancer (NSCLC) patients, which may provide valuable information for the treatment of nonsmall cell lung cancer. We used keywords to retrieve literatures from online databases PUBMED, EMBASE and Web of Science and included 12 studies into our investigation according to pre-set criteria...

MicroRNAs (miRNAs) are identified negatively regulating gene expression and acting as oncogenes or tumor suppressors in tumorigenesis. The association between miR-146a rs2910164 (G>C) polymorphism and susceptibility to digestive system cancers was contradictory and inconsistent in previously published studies. Presently, we performed a comprehensive literature retrieve on PubMed, Web of Science, Embase, Wanfang and CNKI databases to identify all relevant studies published before July 30, 2016. Odds ratio (OR) and 95% confidential interval (95%CI) were used to calculate the relationship between miR-146a rs2910164 (G>C) polymorphism and digestive system cancers susceptibility...
