Interleukin-12 (IL-12) is considered to be a risk factor for cancer; however, its role in hepatocellular carcinoma (HCC) remains unknown. This study aimed to explore the impacts of the IL-12 rs3212227 and rs568408 gene polymorphisms on HCC.
We searched PubMed, Embase, Web of Science, and Chinese Knowledge Infrastructure databases for studies on the associations between HCC and IL-12 rs568408 and rs3212227 polymorphisms published prior to 1 May 2020. The effects of the polymorphisms on HCC susceptibility were presented as odds ratios (ORs) and associated 95% confidence intervals.
Seven studies were ultimately included, including 2375 cases and 3445 controls. The rs3212227 polymorphism was significantly associated with the risk of HCC in both the dominant model (CC+AC vs. AA, OR=1.22) and the allele model (C vs. A, OR=1.12). Combined analysis of rs568408 yielded a significant relative risk for HCC in the dominant (AA+AG vs. GG, OR=1.13), recessive (AA vs. AG+GG, OR=1.72), allele (A vs. G, OR=1.29), heterozygote (AG vs. GG, OR=1.27), and homozygote models (AA vs. GG, OR 1.17).
The IL-12 rs3212227 and rs568408 gene polymorphisms are associated with an increased risk of HCC.
白细胞介素-12（IL-12）被认为是癌症的一个风险因素；然而，其在肝细胞癌（HCC）中的作用尚不清楚。本研究旨在探讨IL-12 rs3212227和rs568408基因多态性对HCC的影响。
我们检索了PubMed、Embase、Web of Science和中国知网数据库，以查找2020年5月1日前发表的关于HCC与IL-12 rs568408和rs3212227多态性之间关联的研究。多态性对HCC易感性的影响以比值比（OR）和相关的95%置信区间表示。
最终纳入7项研究，包括2375例病例和3445例对照。rs3212227多态性在显性模型（CC+AC vs. AA，OR=1.22）和等位基因模型（C vs. A，OR=1.12）中均与HCC风险显著相关。rs568408的合并分析在显性（AA+AG vs. GG，OR=1.13）、隐性（AA vs. AG+GG，OR=1.72）、等位基因（A vs. G，OR=1.29）、杂合子（AG vs. GG，OR=1.27）和纯合子模型（AA vs. GG，OR 1.17）中均产生了HCC的显著相对风险。
IL-12 rs3212227和rs568408基因多态性与HCC风险增加相关。
