Abstract

Previous studies have investigated the role of miR-146a rs2910164 and miR-196a-2 rs11614913 polymorphisms in hepatocellular carcinoma (HCC) susceptibility, but the results are contradictory and few specifically studied hepatitis virus-related HCC. Therefore, we conducted a meta-analysis to evaluate the association between these two polymorphisms and hepatitis virus-related HCC risk. We performed a systematical search in EMBASE, PubMed, Web of Science, CNKI and Wanfang databases as of 25th November, 2016. Finally, we assessed 14 studies involving 3852 cases and 5275 controls. Our results suggest that rs2910164 has a significant association with increased hepatitis virus-related HCC risk in allelic, homozygous, heterozygous, and dominant models (CG+GG vs. CC: OR=1.22, 95% CI=1.06-1.39, P=0.004), particularly in Chinese and HBV-related HCC subgroups. Conversely, rs11614913 was associated with lower hepatitis virus-related HCC risk in the overall analysis under allelic (T vs. C: OR=0.85, 95% CI=0.74-0.98, P=0.02), homozygous, dominant and recessive models. Subgroup analyses showed decreased risk in Chinese, HBV- and HCV-related HCC. In conclusion, miR-146a C>G (rs2910164) can increase HBV-related HCC risk while miR-196a-2 C>T (rs11614913) may decrease the risk of HBV- and HCV-related HCC, especially in the Chinese population. Further, large-scale studies including other races are required to confirm these findings.

摘要

以往的研究探讨了miR-146a rs2910164和miR-196a-2 rs11614913多态性在肝细胞癌(HCC)易感性中的作用,但结果相互矛盾,且很少有专门针对肝炎病毒相关HCC的研究。因此,我们进行了一项荟萃分析,以评估这两种多态性与肝炎病毒相关HCC风险之间的关联。我们截至2016年11月25日在EMBASE、PubMed、Web of Science、中国知网和万方数据库中进行了系统检索。最终,我们评估了14项研究,涉及3852例病例和5275例对照。我们的结果表明,在等位基因、纯合子、杂合子和显性模型中,rs2910164与肝炎病毒相关HCC风险增加显著相关(CG + GG vs. CC:OR = 1.22,95% CI = 1.06 - 1.39,P = 0.004),特别是在中国人群和HBV相关HCC亚组中。相反,在等位基因(T vs. C:OR = 0.85,95% CI = 0.74 - 0.98,P = 0.02)、纯合子、显性和隐性模型的总体分析中,rs11614913与肝炎病毒相关HCC风险降低相关。亚组分析显示,在中国人群、HBV和HCV相关HCC中风险降低。总之,miR-146a C>G(rs2910164)可增加HBV相关HCC风险,而miR-196a-2 C>T(rs11614913)可能降低HBV和HCV相关HCC风险,尤其是在中国人群中。此外,需要包括其他种族的大规模研究来证实这些发现。
