ABSTRACT: Background
This study was aimed to evaluate the association between interleukin-6 (IL-6) gene polymorphisms and the risk of hepatocellular carcinoma (HCC) in a meta-analysis.Methods
A literature search was performed for case-control studies published during May, 1993 to May, 2020 focusing on IL-6 gene polymorphisms (-174G?>?C, -572G?>?C, and -597G?>?A) and HCC susceptibility by using PubMed, Cochrane Database, EMBASE, Web of science, and China National Knowledge Infrastructure. From 128 full-text articles, 11 were included in this meta-analysis. I index was used to assess heterogeneity and Newcastle-Ottawa Scale was utilized for quality assessment.Results
For IL-6 -174G?>?C polymorphism, in codominant (GG vs CC: odds ratios [OR]?=?2.78, 95% confidence intervals [CI]?=?1.25-6.19, P?=?.01, I?=?16%) and recessive (GG+GC vs CC: OR?=?2.76, 95% CI?=?1.29-5.90, P?=?.009, I?=?3%) models, IL-6 -174G>C polymorphism was significantly associated with the risk of HCC. In dominant (GG vs CC+GC: OR?=?1.80, 95% CI?=?0.92-3.54, P?=?.09, I?=?86%) and allele (G vs C: OR?=?1.49, 95% CI?=?0.95-2.32, P?=?.08, I?=?68%) models, IL-6 -174G>C polymorphism had no impact on the risk of HCC. However, in non-Italian Caucasian population, IL-6 -174G>C polymorphism was significantly related to the occurrence of HCC in both dominant (GG vs CC+GC: OR?=?3.26, 95% CI?=?2.29-4.65, P?C and -597G>A polymorphisms, no significant association was observed in all models, regardless of the source of control and population subgroups. No publication bias could be calculated when Begg and Egger tests were employed.Conclusion
This meta-analysis indicated that IL-6 -174G>C polymorphism was significantly related with the risk for HCC, especially in non-Italian Caucasian population. No significant association was observed for the correlation between IL-6 -572G>C and -597G>A polymorphisms and HCC susceptibility.
