It is estimated that 51.5% of HCC cases can be attributed to HCV infection. Moreover, there is a large occult reservoir of HCV caused chronic liver disease in approximately 9 % in the Egyptian with estimated 6 million HCV chronic infections and estimated 150 000 new infections per year. Among them, we have to mention the polymorphism of IL28B gene rs12979860 C/T. and rs 4803217. The IL-28B gene encodes interferon-lambda 3 (IFN-λ3), which belongs to the type III IFN family. IFN-λ interacts with a transmembrane receptor inducing a potent antiviral response. In experimental model of HCV type III IFN was able to inhibit viral replication. IL-28B polymorphisms are linked to the efficiency of the inflammatory process during HCV infection, and to the mechanisms that HCV adopts to escape by innate and adaptive immunity.
