[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.

Assessment of cancer cell differentiation in small hepatocellular carcinoma by computed tomography and magnetic resonance imaging.

Aim: To study whether cancer cell differentiation in small hepatocellular carcinoma (HCC) can be assessed by computed tomography (CT) and magnetic resonance (MR) imaging.

Methods: We retrospectively evaluated the relationship between cancer cell differentiation in 127 HCC 3 cm or less in diameter (113 patients) and CT and MR images. Images were reviewed in a consensus conference by three authors (SA, TY, and ME).
