title: Relationship between the histological degrees of hepatitis and the postoperative recurrence of hepatocellular carcinoma in patients with hepatitis C.
abstract: The relationship between the recurrence of hepatocellular carcinoma (HCC) and the degree of inflammation was evaluated in resected livers with the hepatitis C virus (HCV) -associated HCC. Seventy-three patients with HCV-associated HCC who were followed up for more than 2 years were selected for this study. In these cases, the degree of chronic hepatitis in noncancerous regions at the time of surgery was classified according to the New Inuyama Classification as follows, the degree of necroinflammatory activity (Grading) was graded from A0 to A3, and the degree of fibrosis (Staging) was staged on F0-F4. In addition, among these patients, 41 patients who were followed by blood tests every 3 months were divided into two groups (high or low group) according to annual average levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), the platelet counts (Plt), and alpha-fetoprotein (AFP). As a result, cancer-free survival rate was significantly lower in the high-grade group (A3) than in the low-grade group (A1 or 2) (P=0.01). The high ALT (>80 IU) group and the high AFP (>20 mg/ml) group also had significantly worse cancer-free survival rate than the low ALT group and the low AFP group (P=0.04 for ALT, P=0.03 for AFP). A multivariate analysis for the prognostic values revealed the AFP level (P=0.02) and the Grading (P=0.04) were useful as independent prognostic factors concerning recurrence. In conclusion, the degree of inflammatory activity (Grading) is considered to be a useful factor regarding recurrence after liver resection in patients with HCC. Furthermore, the inhibition of inflammation in remnant liver may also contribute to the prevention of recurrence.
