We searched CISCOM, CINAHL, Web Science, PubMed, Google Scholar, EBSCO, Cochrane Library, CBM databases from inception through August 1, 2013. Meta-analysis was performed using STATA 12.0 software. Odds ratios (ORs) 95% confidence intervals (CIs) were calculated under fixed- or random-effects models. Twenty-seven clinical cohort included total 3311 CRC patients. Our revealed associated pathological characteristics (tumor, nodes, metastasis stage: OR=1.55, CI: 1.14–2.13, p=0.006; lymph node metastasis: OR=2.40, 1.37–4.19, p=0.00...
