Abstract
PURPOSE: This 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. METHODS: We examined 781 patients who underwent hepatic resection for HCC. They were classified into NBNC-HCC, SVR-HCC, and non-SVR HCC groups. RESULTS: Multivariate 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). CONCLUSIONS: NBNC-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.
