Associations between transforming growth factor (TGF)-β1 polymorphisms and hepatocellular carcinoma (HCC) risk remained controversial. Therefore, we performed this meta-analysis to investigate these associations.
We searched Pubmed, EMBASE, Chinese National Knowledge Infrastructure (CNKI), and Wanfang databases for studies before March 2013. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to calculate the strength of association.
A total of 14 studies were included in this meta-analysis. TGF-β1 +869C/T polymorphism was significantly associated with HCC risk (OR=1.74, 95% CI: 1.22-2.47, p=0.002). In addition, a significant association between -509C/T polymorphism and HCC risk was observed (OR=1.40, 95% CI: 1.15-1.70, p=0.0007). Furthermore, significant associations between these polymorphisms and HCC risk were found in Asians and population-based studies.
Our meta-analysis suggested that the TGF-β1 +869C/T and -509C/T polymorphisms may be risk factors for developing HCC.
转化生长因子(TGF)-β1基因多态性与肝细胞癌(HCC)风险之间的关联仍存在争议。因此,我们进行了这项荟萃分析以研究这些关联。
我们检索了截至2013年3月之前发表在PubMed、EMBASE、中国知网(CNKI)和万方数据库中的研究。采用比值比(OR)及95%置信区间(CI)计算关联强度。
本荟萃分析共纳入14项研究。TGF-β1 +869C/T基因多态性与HCC风险显著相关(OR=1.74,95%CI:1.22-2.47,P=0.002)。此外,还观察到-509C/T基因多态性与HCC风险之间存在显著关联(OR=1.40,95%CI:1.15-1.70,P=0.0007)。此外,在亚洲人群和基于人群的研究中发现这些多态性与HCC风险之间存在显著关联。
我们的荟萃分析表明,TGF-β1 +869C/T和-509C/T基因多态性可能是HCC发生的危险因素。
