| Outline of Final Research Achievements |
For 414 cases diagnosed as primary hepatocellular carcinoma (HCC) at nine facilities in Tottori Prefecture from 2017 to 2019, surveillance for patients in the HCC high-risk group and risk factors for non-B non-C (NBNC) HCC were examined. The surveillance rate was 53.2% for hepatitis B virus (HBV), 32.8% for untreated hepatitis C virus (HCV), 95.5% for HCV (DAA-SVR), 68.8% for HCV (IFN-SVR), 14.0% for NBNC (non-ALD) (non-ALD; nonalcoholic), and 13.7% for NBNC (ALD). Patients who were HBV/HCV positive but were accidentally diagnosed with HCC didn't have a regular medical examination and had no history of HBV/HCV testing. The incidence of diabetes mellitus (DM) in 129 patients with NBNC (non-ALD) HCC was as high as 48.8%, and FIB-4 index 2.67 or higher was 35.7%. These results indicate that introduction of HCC surveillance for patients with DM and FIB-4 index 2.67 or higher may be able to diagnose about 30% of NBNC (non-ALD) HCC at early stages.

| Academic Significance and Societal Importance of the Research Achievements |
現在、非B非C型（NBNC）肝細胞癌（HCC）は偶発的に進行した状態で診断されることが多いが、FIB-4 index 2.67以上の糖尿病患者をその高危険群に設定してサーベイランスを行うことにより、NBNC HCC患者の予後改善が期待され、学術的・社会的意義は極めて大きいと考える。糖尿病かつFIB-4 index 2.67以上の条件を満たさないNBNC HCCやアルコール性HCCの早期診断対策は未解決の課題であり、今後の研究の進展が待たれる。
