BACKGROUND In clinical trials, a pangenotype direct-acting antiviral (DAA) regimen consisting of glecaprevir (GLE) and pibrentasvir (PIB) exhibited high virologic efficacy and tolerability in patients with hepatitis C virus (HCV) infection. This study sought to confirm these findings in real-world settings, focusing on patients with cirrhosis, history of DAA failure, or HCV genotype 3 who were treated with a 12-week regimen in a large multicenter study from Japan. METHODS In a nationwide multicenter prospective cohort study, we analyzed background characteristics, tolerability, and treatment outcome of patients who underwent a 12-week GLE/PIB regimen. RESULTS Of 1190 patients, 509 (42.8%) underwent the 12-week regimen, and the remaining patients underwent an 8-week regimen. The rate of sustained virologic response (SVR) of patients treated with the 12-week regimen was 99.0%, comparable with that of patients treated with the 8-week regimen. The adverse events were observed in 29.1% of patients. The main adverse event was pruritus, which was observed in 14.7%. Ten patients (2.0%) discontinued therapy during treatment period. CONCLUSION The 12-week GLE/PIB regimen was well-tolerated with high virologic efficacy in patients with cirrhosis, experience of DAA, or HCV genotype 3; tolerability and SVR rate were comparable with those of DAA-naive, non-cirrhotic, non-genotype 3 patients who underwent 8-week regimen.

BACKGROUND AND AIM Aldo-keto reductase family 1 member B10 (AKR1B10), a cancer-related oxidoreductase, was recently reported to be upregulated in some chronic liver diseases. However, its relevance in hepatocellular carcinoma (HCC) development is not fully assessed, especially in patients with chronic hepatitis C virus (HCV) infection. METHODS Aldo-keto reductase family 1 member B10 expression in the liver of 550 patients with chronic HCV infection was immunohistochemically assessed and quantified. A multivariate Cox model was used to estimate the hazard ratios (HRs) of AKR1B10 expression for HCC development, and the cumulative incidence of HCC was evaluated using the Kaplan-Meier method. RESULTS Aldo-keto reductase family 1 member B10 expression in the patients ranged from 0% to 80%. During the median follow-up of 3.2 years, 43 of 550 patients developed HCC. Multivariate analysis demonstrated that high AKR1B10 expression (≥6%) was an independent risk factor for HCC (HR, 6.43; 95% confidence interval, 2.90-14.25; P

Background and Aim The purpose of this study was to evaluate the usefulness of liver stiffness measurement (LSM) for assessing the risk of hepatocellular carcinoma (HCC) in chronic hepatitis C (CHC) patients receiving interferon (IFN) therapy. Methods One hundred fifty-one CHC patients who underwent LSM and received IFN therapy were included in the estimation cohort, and 56 were included in the validation study. The cumulative HCC incidences were evaluated using Kaplan–Meier plot analysis and the log-rank test. Multivariate Cox proportional hazard analyses were used to estimate the hazard ratios (HRs) of variables for HCC. Results In the estimation cohort, 9 of 151 patients developed HCC during the median follow-up time of 722 days. Multivariate analysis identified three independent risk factors for HCC: LSM (≥ 14.0 kPa, HR 5.58, P = 0.020), platelet count (

Multivariate analysis demonstrated that high AKR1B10 expression (≥6%) was an independent risk factor for HCC (HR, 6.43; 95% confidence interval, 2.90-14.25; P 0.001). The 5-year cumulative incidences of HCC were 22.8% and 2.2% in patients with high and low AKR1B10 expression, respectively (P 0.001). In subgroup analyses, the effects of high AKR1B10 expression on HCC development risk were significant over strata. In particular, HRs attributed to high AKR1B10 expression were significant in the subgroups that had been considered at a lower risk of HCC, such as in patients with younger age and mild hepatic fibrosis or those who achieved sustained virological response after interferon therapy.Various degrees of AKR1B10 upregulation in the liver were observed in patients with chronic HCV infection, and high AKR1B10 expression could be a novel predictor of HCC.

Background and Aims: Correlation between the gross classification of hepatocellular carcinoma (HCC) and its vascular invasion or intrahepatic metastasis has been reported previously. Because E-cadherin-mediated epithelial cell-to-cell adhesion is thought to suppress cancer cell invasion, the present study was performed to analyze the correlation between E-cadherin expression and the gross classification of HCC. Methods: Thirty-six resected solitary HCC

The purpose of this study was to evaluate the usefulness of liver stiffness measurement (LSM) for assessing the risk of hepatocellular carcinoma (HCC) in chronic hepatitis C (CHC) patients receiving interferon (IFN) therapy.One hundred fifty-one CHC patients who underwent LSM and received IFN therapy were included in the estimation cohort, and 56 were included in the validation study. The cumulative HCC incidences were evaluated using Kaplan-Meier plot analysis and the log-rank test. Multivariate Cox proportional hazard analyses were used to estimate the hazard ratios (HRs) of variables for HCC.In the estimation cohort, 9 of 151 patients developed HCC during the median follow-up time of 722 days. Multivariate analysis identified three independent risk factors for HCC: LSM (≥ 14.0 kPa, HR 5.58, P = 0.020), platelet count ( 14.1 × 10(4) /μL, HR 5.59, P = 0.034), and non-sustained virological response (HR 8.28, P = 0.049). The cumulative incidence of HCC development at 3 years was 59.6%, 8.2%, and 0.0% in patients with all three risk factors, one to two risk factors, and none of these risk factors, respectively. The incidence of HCC was significantly different between these groups (P 0.001). In the validation cohort, HCC incidence was also significantly different with respect to these risk factors (P = 0.037).LSM, platelet count, and IFN-therapeutic effect could be used to successfully stratify the risk of HCC in patients receiving IFN therapy and demonstrate the usefulness of LSM before IFN therapy for the management of CHC patients.

Background and Aims: There is currently no proven chemotherapy regimen for hepatocellular carcinoma (HCC). The principal chemotherapeutic approach in most cases is infusion therapy into the hepatic arteries feeding the tumors. However, the clinical effects of chemotherapy are extremely poor. Therefore, in the present study, we conducted a prospective randomized trial of the efficacy of oral administration of enteric-coated tegafur/uracil for advanced HCC. Methods: From 1994 to 1999, a total of 56 consecutive patients with unresectable stage IV-A HCC were studied prospectively to examine the efficacy of enteric-coated tegafur/uracil in HCC and to determine the significant prognostic factors. Twenty-eight patients were treated only with enteric-coated tegafur/uracil without other anticancer treatment. Another 20 patients were given conservative management only. The remaining eight patients withdrew from the study, conservative man Results: In the group treated only with enteric-coated tegafur/uracil, the median survival time and 1 and 2 year survival rates were 12.13 months and 55.3 and 36.9%, respectively. In the control group, the median survival time and 1 year survival rate were 6.20 months and 5.5%, respectively. By both univariate analysis and multivariate analysis using Cox's proportional hazards model, treatment with enteric-coated tegafur/uracil was shown to be the factor most significantly favoring a better prognosis. Conclusions: Although the prognosis of most patients with stage IV-A HCC is poor, administration of enteric-coated tegafur/uracil induces long-term survival and is an effective treatment for stage IV-A HCC.
