Beschreibungen/Notizen

• Although there have been many studies of the risk factors for recurrence after resection of hepatocellular carcinoma (HCC), the subjects were patients with various viral status in the previous studies, and hepatitis C viremia has not been evaluated. We investigated risk factors, including hepatic C viremia and histologic findings of noncancerous hepatic tissue, for recurrence after resection of hepatitis C virus (HCV)‐related HCC. A total of 223 patients who underwent liver resection for HCV‐related HCC were studied. HCV viremia, laboratory data, degree of HCC malignancy, histologic findings in noncancerous hepatic tissue, preoperative interferon therapy, and operative methods were evaluated for recurrence risk by univariate and multivariate analyses. Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin, and the proportion of patients with a high histologic activity score (mild to severe active hepatitis) were significantly higher in patients with HCV viremia than in those without viremia. Serum albumin was significantly lower in patients with HCV viremia. By univariate analysis, older age (> 65 years old), HCV viremia, elevated AST (> 40 IU/L) and ALT (> 45 IU/L), large tumors (> 40 mm), multiple HCCs, moderately or poorly differentiated HCC, portal invasion, mild to severe active hepatitis, and lack of preoperative interferon therapy were risk factors for recurrence. Multivariate analysis showed that older age, HCV viremia, high AST, multiple HCCs, and portal invasion were independent risk factors. For HCV‐related HCCs, not only the degree of maliganacy of the HCC but also HCV viremia and active hepatitis are risk factors for recurrence.
