Abstract:
Objective To investigate the association between single nucleotide polymorphisms (SNPs)in cytokine IL-6, IL- 10 genes and HBV-related hepatocellular carcinoma(HCC). Methods A hospital-based case-control study was conducted in 381 cases with HBV-related HCC, 340 HBsAg carriers and 359 non-tumor controls. Genotypes of-572 site of IL-6 gene and-819, -592 sites of IL-10 gene were determined by real-time polymorphism chain reaction. Unconditional logistic regression was used to estimate the odds ratios(ORs)and 95 confidence intervals(C/s). Results For the G/C alleles of -572 loci on IL-6 gene, there were significant differences between the three groups(P＜0.05). Compared with CC genotype, GG genotype increased the risk of HBV infection (OR=2.171,95% Ch 1.068-4.415), but did not seem to be associated with HCC. For the alleles of-819 and -592 site of IL-10 gene, there were significant differences between the three groups(P＜0.05). Compared with CC genotype, TT genotype increased the risks of both HCC(OR=2.791,95%CI:1.326-5.874), and HCC in HBsAg carriers(0R=3.522,95%CI: 1.707-7.266). When compared with CC genotype on -592 site, the AA genotype reduced the risk of both HCC(OR=0.389, 95% CI:0.173-0.875), and HCC in HBsAg carriers(OR=0.336, 95% CI: 0.154-0.734). Conclusion The SNPs in -572 site of IL-6 gone might be associated with the risk of HBV infection. The SNPs in -819 site of IL-10 gene increased the risk of HCC, but -592 site of IL-10 gene decreased the risk of HCC.
