XRCC1-399 allele polymorphisms have been reported to be associated with susceptibility to hepatocellular carcinoma (HCC), but the conclusions of the various studies have been inconsistent. We conducted a meta-analysis of available studies to determine whether XRCC1-399 alleles influence susceptibility to hepatocellular carcinoma. We searched English-language databases, including PubMed, Medline and Embase, using terms such as "hepatocellular carcinoma" (or "HCC"), "X-ray repair cross-complementing group 1" (or "XRCC1") and "genetic polymorphism" (or "SNP"), among others; we also searched Chinese-language databases, including CNKI, VIP, Wanfang Data, and CBM, using terms such as "ganai", "ganxibaoai", "ganzhongliu", "duotaixing", and "X-xian xiufu jiaocha hubu jiyin 1". Eight independent studies, including 1604 HCC cases and 2185 controls, were included. The pooled odds ratio for XRCC1-399 was 0.99 (95% confidence interval = 0.75-1.31). We conclude that XRCC1- 399 gene polymorphisms are unrelated to risk for HCC.
据报道,XRCC1 - 399等位基因多态性与肝细胞癌(HCC)易感性相关,但各项研究结论并不一致。我们对现有研究进行了荟萃分析,以确定XRCC1 - 399等位基因是否影响肝细胞癌易感性。我们使用了“肝细胞癌”(或“HCC”)、“X射线修复交叉互补组1”(或“XRCC1”)和“基因多态性”(或“SNP”)等术语检索了英文数据库,包括PubMed、Medline和Embase;我们还使用了“肝癌”、“肝细胞癌”、“肝肿瘤”、“多态性”和“X线修复交叉互补基因1”等术语检索了中文数据库,包括中国知网、维普资讯、万方数据和中国生物医学文献数据库。纳入了8项独立研究,包括1604例HCC病例和2185例对照。XRCC1 - 399的合并比值比为0.99(95%置信区间 = 0.75 - 1.31)。我们得出结论,XRCC1 - 399基因多态性与HCC风险无关。
