Outcomes of Non-B Non-C Hepatocellular Carcinoma with Reference to Patients with Interferon-Induced Hepatitis C Virus Eradication

Abstract

PurposeThis study aimed to evaluate survival outcomes in patients with non-B non-C hepatocellular carcinoma (NBNC-HCC) with reference to patients with HCC achieving sustained virological response (SVR) by preoperative interferon (IFN) treatment for chronic hepatitis C. MethodsWe examined 781 patients who underwent hepatic resection for HCC. They were classified into NBNC-HCC, SVR-HCC, and non-SVR HCC groups. ResultsMultivariate analysis for recurrence-free survival (RFS) and overall survival (OS) revealed that the adjusted hazard ratios (HR) of NBNC-HCC and non-SVR HCC groups with reference to the SVR-HCC group were 1.46 (p = 0.10) and 2.10 (p < 0.001), respectively, for RFS, and 1.69 (p = 0.024) and 2.11 (p < 0.001), respectively, for OS. Worsening of Child–Pugh grade at recurrence was confirmed in 21 patients (17.1%) with NBNC-HCC but not in those with SVR-HCC (p = 0.017, SVR vs. NBNC). In the NBNC-HCC group, hepatic resection for intrahepatic recurrence was adopted in 17.4% of patients without worsening of Child–Pugh grade at recurrence, whereas hepatic resection was not adopted in those with grade worsening. Among patients with alcoholic hepatitis, Child–Pugh grade worsening at recurrence was more frequently observed in patients with sobriety than those without sobriety (14.3% vs. 46.2%, p = 0.049). ConclusionsNBNC-HCC patients had an increased risk for overall death as compared with those with SVR-HCC. Worsening of background liver function may reduce the chances of re-hepatic resection for recurrence and increase the risk for overall death in NBNC-HCC patients. For alcoholic hepatitis patients, sobriety may prevent deterioration of liver function after surgery.
