Background/Aims: Hepatitis C virus (HCV) associated HCC shows a high rate of recurrence even after curative treatment. Outcomes of pegylated interferon PEGIFN a-2b/ribavirin (RBV) therapy for HCV-associated HCC have yet to be elucidated. We investigated therapeutic response and hepatic functional reserve improvement in patients receiving PEG-IFN a-2b/RBV after curative HCC treatment. Methodology: We investigated survival rate, metachronous recurrence and hepatic functional reserve in 54 patients with initial HCV-associated Stage I/II HCC; 29 patients were administered a preparation of PEG-IFN a-2b/RBV after HCC treatment (Secondary IFN group) and 25 were not (Non-secondary IFN group). Results: A significant difference was observed in cumulative survival rates among HCV-associated HCC patients with rates of 100% after 1 year and 90.2% after 3 years in the secondary IFN group compared to 96.0% and 61.2%, respectively, in the non-secondary IFN group. Univariate analysis identified secondary IFN treatment, alanine aminotransferase and albumin levels as factors contributing to survival. Serum albumin level decreased temporarily but subsequently increased and improved hepatic functional reserve was observed in PEG-IFN a-2b/RBV therapy. Conclusions: PEG-IFN a-2b/RBV therapy after HCC treatment can improve hepatic functional reserve and may therefore represent a therapeutic option in the event of recurrence. PEG-IFN a-2b/ RBV therapy following HCC treatment shows promise for improving the prognosis of HCC.

    • "Nine studies including 949 cases [9-11,13-18] compared the IFN group and the control group with regard to the death rates of HCC. Taking OR as an indicator of the effect of measures, we performed a χ2 test to examine the heterogeneity; the result was P = 0.54 (>0.10), "

    ABSTRACT: To evaluate the efficacy and safety of adjuvant IFN therapy for viral hepatitis-related hepatocellular carcinoma (HCC) after treatment with surgical resection or transarterial chemoembolization (TACE). Controlled trials of adjuvant treatment with IFN for patients with HCC published between 2000 and 2012 were searched electronically in MEDLINE, PubMed, Cochrane Library, and EMBASE databases. According to the heterogeneity of the studies, two different models - the fixed-effect model and the random-effect model - were applied to analyze the results. Ten trials were screened according to inclusion and exclusion standards. Eight randomized, controlled trials and two non-randomized, controlled trials were included. These ten trials with a total of 1,029 subjects were eventually involved in the meta-analysis; 528 HCC patients were treated with adjuvant treatment with IFN and 501 patients with placebo. Compared to the control group, the recurrence rates of HCC in IFN group were significantly lower (odds ratio (OR) = 0.66; 95% confidence interval (CI) = 0.50 to 0.86; P = 0.02), especially after TACE treatment according to subgroup analysis (OR = 0.73; 95% CI = 0.52 to 1.01; P = 0.06 for surgical resection; and OR = 0.54; 95% CI = 0.33 to 0.86, P = 0.01 for TACE). The death rates in the IFN group also significantly decreased according to not only total events analysis (OR = 0.42; 95% CI = 0.32 to 0.56; P < 0.00001) but also subgroup analysis (OR = 0.51; 95% CI = 0.36 to 0.72; P = 0.0002 for surgical resection; and OR = 0.33; 95% CI = 0.21 to 0.50; P < 0.00001 for TACE). Adjuvant IFN therapy may significantly reduce the recurrence rates of patients with viral hepatitis-related HCC and improve the survival of patients after surgical resection or TACE. The ideal dose mostly selected is 3 MIU/ml, three times per week, which can make patients tolerate the adverse reactions of IFN better and maintain effective concentrations for a long time.

    ABSTRACT: Hepatocellular carcinoma (HCC) is a fatal disease. Chronic hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infection is the major cause of HCC. High viral replication rate and related hepatic/systematic inflammation are the major risk factors in HCC recurrence after hepatectomy or liver transplantation. Some of the carcinogenesis-related HBV mutations are also associated with poor prognosis for HCC patients. Antiviral therapy is an option for improving HCC prognosis after surgery. In case of HBV-associated HCC, treatment with interferon and nucleos(t)ide analogues (NAs), especially interferon, is effective in improving the prognosis. However, long-term use of NAs increases the possibility of developing drug-resistant viral mutations such as the HBV rtA181T/sW172 mutation, which increases the risk of HCC recurrence. In cases of HCV-associated HCC, standard interferon with or without ribavirin therapy is effective in improving the prognosis of HCV-associated HCC; however, some HCV mutations, such as the amino acid substitution M91L, are associated with treatment failure and a poor prognosis. Therapeutic efficacy needs to be confirmed using largescale, randomized, placebo-controlled clinical trials. Surveillance of viral mutations during antiviral treatment and a better understanding of the associations of HCC recurrence with viral load, inflammation-associated signaling, and environmental factors can aid the development of more effective strategies for the prevention of HCC recurrence after surgery.

    ABSTRACT: The combination therapy with peginterferon and ribavirin has been used to treat chronic hepatitis C for several years in Korea but there is a few report about the results of the treatment. We evaluated safety and efficacy of the combination therapy with Peg-interferon and ribavirin and analyzed factors that may affect treatment.
