Core tip: Cytokines have a decisive role in the pathophysiology of many infectious, autoimmune and malignant diseases. Changes in cytokine secretion profile are involved in one way or another in susceptibility to hepatitis B virus (HBV) and hepatitis C virus (HCV) infection and eventualy are thought to influence the disease phenotype and the rapid progression to HCC. Individual variation in cytokine profile might, at least partially, to genetic alteration within the regulatory regions of cytokine genes. One of the most studied phenomena is the allelic polymorphism and its implication in cytokine gene expression, and the susceptibility to infection, clinical severity of diseases and response to treatment. This review concentrates on the cytokine gene polymorphism case-control and meta-analysis studies performed all over the world on hepatocellular carcinoma patients (as a consequence to HBV or HCV infection).
