We analyzed the outcomes of a cohort of patients with HCC who received either sorafenib (Sor), lenvatinib (Len) or atezolizumab plus bevacizumab (Atezo + Bev) as first-line systemic therapy for HCC, with the aim of identifying prognostic factors for survival.

Methods: A total of 825 patients with advanced HCC and Child-Pugh A or B received either Sor, Len or Atezo + Bev as first-line systemic therapy.

Construction of an anti-hepatitis B virus preS1 antibody and usefulness of preS1 measurement for chronic hepatitis B patients: Anti-HBV PreS1 antibody.

Objectives: The preS1 region plays an essential role in hepatitis B virus (HBV) infection. We construct an antibody that binds to preS1 and a measurement system for serum preS1 in chronic HBV-infected patients.

Methods: Hybridoma clones that produce anti-preS1 antibodies were obtained by the iliac lymph node method.

Background: We previously reported on the trends in the etiologies of hepatocellular carcinoma (HCC) diagnosed in patients between 1995 and 2009. The aims of our updated study were to evaluate the incidence, nonhepatitis B and nonhepatitis C viral (NBNC) etiologies, and clinical characteristics of HCCs occurring in patients between 1992 and 2018.

Methods: The study enrolled 2171 consecutive patients with HCC between 1992 and 2018.

Complete Response for Advanced Hepatocellular Carcinoma by Conversion Surgery Therapy Following a Good Response of Regorafenib Despite Rapid Progressive Disease with Sorafenib.

A 68-year-old man with hepatocellular carcinoma (HCC) visited his previous hospital due to abdominal pain and was diagnosed with ruptured HCC. Before visiting our hospital, he underwent HCC treatment at his previous hospital, but his tumors did not improve. Although he started treatment with sorafenib, the tumors rapidly grew.

Therapeutic effects of sleeve gastrectomy for non-alcoholic steatohepatitis estimated by paired liver biopsy in morbidly obese Japanese patients.

Bariatric surgery has been reported to improve non-alcoholic steatohepatitis (NASH), which is a frequent comorbidity in morbidly obese patients. We performed a retrospective cohort study to estimate the therapeutic effect of sleeve gastrectomy (SG), the most common bariatric surgery in Japan, on obese patients with NASH by comparing the findings of paired liver biopsies.Eleven patients who underwent laparoscopic SG for the treatment of morbid obesity, defined as body mass index (BMI) > 35 kg/m2, from March 2015 to June 2019 at Hiroshima University Hospital, Japan, were enrolled.

Serum PreS1 and HBsAg ratio reflects liver fibrosis and predicts the development of hepatocellular carcinoma in chronic hepatitis B patients.

While the preS1 region of the large hepatitis B surface protein plays an essential role in hepatitis B virus (HBV) infection, the effect of preS1 on liver fibrosis and hepatocarcinogenesis in chronic hepatitis B (CHB) patients is not well known. In this study, we measured serum preS1 levels by chemiluminescent immunoassay technology in 690 CHB patients and evaluated the correlation between serum preS1 levels and HBV, liver function markers and liver inflammation, fibrosis assessed by histological findings. Predictive factors for hepatocellular carcinoma (HCC) development in patients who had no previous history of HCC at the time of preS1 level measurement were also analysed.

Case Presentation: A previously healthy 66-year-old man had a persistent fever and developed ALF of unclear etiology.

Extracellular water to total body water ratio obtained by bioelectrical impedance analysis determines the dose intensity of lenvatinib for the treatment of patients with advanced hepatocellular carcinoma.

Background And Aim: The aim of this study was to identify the factors that contribute to the maintenance of relative dose intensity (RDI) of lenvatinib in hepatocellular carcinoma (HCC) patients.

Methods: Thirty-two patients with advanced HCC treated with lenvatinib were enrolled. We evaluated the relationship between maintenance of RDI and various clinical data, parameters obtained by body composition measurements with bioelectrical impedance analysis (BIA) and grip strength at the start of lenvatinib treatment.

A case with life-threatening secondary sclerosing cholangitis caused by nivolumab.

Immune checkpoint inhibitor (ICI) therapy has potent anti-cancer effects but is associated with immune-related adverse events (irAEs). We present a case who developed secondary sclerosing cholangitis following treatment with nivolumab for non-small cell lung cancer who did not respond to immunosuppressive treatments and died of liver failure. A 75 year-old male with lung cancer who had been treated with nivolumab for non-small cell lung cancer developed Grade 3 liver injury with significant elevation of hepatobiliary enzymes.

Abatacept treatment for patients with severe acute hepatitis caused by hepatitis B virus infection-Pilot study.

Although glucocorticoids have been used for immunosuppression of patients with primary hepatitis B virus (HBV) infection-induced severe hepatitis, the treatment is associated with a high frequency of adverse events. We conducted a pilot study for evaluating the efficacy and safety of abatacept, a cytotoxic T lymphocyte antigen-4 immunoglobulin (CTLA4), for acute hepatitis B. Five patients with severe acute hepatitis B (prothrombin activity ≤ 60%) were treated for immunosuppression by abatacept.

analysis of hepatic stellate cell activation influenced by transmembrane 6 superfamily 2 polymorphism.

Non‑alcoholic steatohepatitis (NASH) may progress via liver fibrosis along with hepatic stellate cell (HSC) activation. A single nucleotide polymorphism (SNP; rs58542926) located in transmembrane 6 superfamily 2 () has been reported to be significantly associated with fibrosis in patients with NASH, but the precise mechanism is still unknown. The present study aimed to explore the role of TM6SF2 in HSC activation .

Aim: We analyzed the impact of hepatitis C virus eradication by direct-acting antiviral (DAA) therapy on the risk of development of hepatocellular carcinoma (HCC), prognosis, and portal hypertension in patients with liver cirrhosis.

Methods: The rate of HCC development and overall survival after achievement of sustained virological response (SVR) in 173 DAA-treated compensated cirrhosis patients without HCC history were retrospectively compared with that of 125 cirrhosis patients who achieved SVR by interferon (IFN)-based therapy or that of 85 cirrhosis patients who failed to respond to anti-HCV therapy. Changes in esophagogastric varices (EGV) and incidence of portosystemic encephalopathy were analyzed in 87 consecutive cirrhosis patients.

Trends in Hepatic Functional Reserve of Patients with Hepatocellular Carcinoma Treated with Tyrosine Kinase Inhibitors.

Objective: Functional hepatic reserve is important when considering sequential tyrosine kinase inhibitor (TKI) therapy for patients with advanced hepatocellular carcinoma (HCC). We assessed albumin-bilirubin (ALBI) score and Child-Pugh class as indices of liver function during sorafenib and lenvatinib treatment.

Methods: A total of 212 patients with advanced HCC and Child-Pugh class A status who initiated TKI treatment at our hospital were enrolled in this retrospective cohort study.

Tumor Fibroblast Growth Factor Receptor 4 Level Predicts the Efficacy of Lenvatinib in Patients With Advanced Hepatocellular Carcinoma.

Objectives: Biomarkers for optimizing the outcome of treatment with lenvatinib in patients with advanced hepatocellular carcinoma remain to be established despite intensive and comprehensive genomic research. Lenvatinib is characterized by its prominent inhibitory potency for fibroblast growth factor receptor (FGFR) 4 compared with earlier tyrosine kinase inhibitors. Thus, in this study, we focused on simplified quantification of FGFR4 in tumors as a potential predictive indicator.

Skeletal Muscle Loss during Tyrosine Kinase Inhibitor Treatment for Advanced Hepatocellular Carcinoma Patients.

Incidence of microsatellite instability-high hepatocellular carcinoma among Japanese patients and response to pembrolizumab.

Aim: Pembrolizumab has been quickly approved in many countries for the treatment of patients with unresectable or metastatic, microsatellite instability-high (MSI-H) solid tumors, which have progressed following previous treatment and who have no satisfactory alternative treatment options. We aimed to determine the incidence of MSI-H tumors in Japanese patients with advanced hepatocellular carcinoma (HCC).

Methods: We investigated the incidence of MSI-H tumors in 82 consecutive Japanese patients with unresectable HCC that had progressed after standard of care treatment.
