| Outline of Final Research Achievements |
We investigated characteristics of hepatocellular carcinoma (HCC) development after the initiation of nucleos(t)ide analogue treatment in chronic hepatitis B patients from a viewpoint of clinical, viral, and host factor. First, liver cirrhosis status and high serum fibrosis marker levels at baseline were the significant risk factors of developing HCC. Second, we analyzed genetic heterogeneity of hepatitis B virus (HBV) by Next-Generation-Sequencing. Of the HBV full-length sequences, amino acid substitution in the polymerase region was significantly associated with HCC development. Third, we examined single nucleotide polymorphisms (SNP) by the Real-Time PCR Assay. Our results suggested that SNP in HLA gene was significantly associated with HCC development among 18 SNPs.
