IL6 and hepatocellular carcinoma: Our results show a significant increase risk of developing hepatocellular carcinoma with the mutation within Interleukin-6 gene with heterozygous G allele (rs2069837) (OR = 10.667, 95%CI = 3.923–29.001, p = < 0.0001) and heterozygous T allele (rs17147230) (OR = 75.385, 95%CI = 9.797–580.065, p = < 0.0001).
