Our meta-analysis showed that the expression of H19 was associated with distant metastasis in nongastrointestinal tumors (OR = 3.85, 95% CI = 1.31–11.36, P = 0.01) and, in gastrointestinal tumors (OR = 0.34, 95% CI = 0.15–0.78, P = 0.01), lymph node metastasis (OR = 2.04, 95% CI = 1.19–3.48, P = 0.009). This evidence concerns the gene H19 and digestive system neoplasm.
