Abstract:

AIM:This Meta-analysis including only Chinese primary hepatocellular carcinoma (PHC) patients was conducted to assess the associations of miR-146a G>C(rs2910164) with PHC risk.  METHODS: Literatures were researched using PubMed, Cochrane Library, Wanfang and China National Knowledge Infrastructure(CNKI) databases to identify relevant studies from the establishment of database to March 2017. Stata software (version 12.0) was used to check odds ratio (OR) and 95% confidence interval (CI). RESULTS: A total of nine published case studies were included in this Meta-analysis, which included 3 937 cases and 5 025 controls. The result suggested SNP was associated with PHC risk in dominant model [(GG+GC)/CC][1.26, (1.12-1.41), P=0.00], recessive model[GG/(GC+CC)][1.23,(1.12-1.34), P=0.00]and allele model(G/C)[1.17, (1.10-1.25), P=0.00]under random effect and fixed effect. Heterogeneity was found among and within studies. Meta regression indicated that the effect size was positively correlated with sample region in dominant model. Subgroup analysis revealed a significant association of this SNP with PHC risk among studies of people from middle-eastern and western area and people using PCR-RFLP, but no such association was found using Non-PCR-RFLP and in studies of people from southwestern area. Three genotypes presented stable sensitivity and absent publication bias. CONCLUSION: miR-146a G>C is associated with PHC risk in Chinese population, and G allelic increased the PHC risk, this SNP may be a biomarker for PHC occurrence.
