[Occurrence and prognosis of hepatocellular carcinoma].

Tomiura, a rural area of Chiba Prefecture in which community-based HCV screening has been carried out since 1991, is known as a high-incidence area of HCV. This study was conducted to clarify the clinical characteristics of subjects with positive HCV antibody titer found on mass survey, in relation to the development and outcome of hepatocellular carcinoma. We analyzed clinical data of patients with positive HCV antibody test results followed up for 9 to 11 years after the mass survey examinations.
