Factors associated with the response to atezolizumab/bevacizumab combination therapy for hepatocellular carcinoma.

Background And Aim: The purpose of this study was to analyze factors associated with the overall survival (OS) of atezolizumab/bevacizumab combination therapy for advanced hepatocellular carcinoma (aHCC). We also assessed the OS of patients with ineffective therapy and those who discontinued treatment owing to adverse events (AEs).

Methods: This retrospective multicenter study involved 139 patients with aHCC who received atezolizumab/bevacizumab combination therapy between November 2020 and September 2022.

Significance of post-progression therapy after tyrosine kinase inhibitors for advanced hepatocellular carcinoma.

Background And Aim: Molecular-targeted therapies such as sorafenib and lenvatinib have long been used as first-line treatment for advanced hepatocellular carcinoma (aHCC). However, adverse events or limited therapeutic effects may necessitate the change to another therapeutic option, known as post-progression therapy. To investigate the significance of post-progression therapy, we analyzed the outcomes of aHCC patients following first-line molecular-targeted therapy in a real-world study.

Acid-treated high-amylose corn starch suppresses high-fat diet-induced steatosis.

Resistant starch (RS) has been reported to improve steatosis as well as obesity. Type 4 resistant starch (RS4), a chemically modified starch, is particularly hard to digest and suggesting higher efficacy. However, because the effects of RS4 on steatosis are not yet fully understood, the effects of RS4 on steatosis were examined using a murine high-fat diet model.

Jejunal variceal rupture in a patient with myelofibrosis: a case report.

An 80-year old man with myelofibrosis and chronic renal disease was admitted to our hospital because of severe anemia and gastrointestinal bleeding. Although no bleeding was observed by upper or lower endoscopy, contrast-enhanced computed tomography revealed an enhanced area in the small intestinal wall that was suspected of being the bleeding site, and was confirmed by double-balloon endoscopy. Based on endoscopic findings, it was difficult to differentiate between variceal rupture and collapse of a submucosal tumor.

Beta-catenin-activated hepatocellular adenoma in a male.

Beta-catenin-activated hepatocellular adenoma is potentially malignant and warrants careful follow-up and surgical resection. Here, we report a 48-year-old man in whom a 55 mm single liver tumor was incidentally detected in the S1 segment. Contrast-enhanced computed tomography scans showed no enhancement in the early phase and a slight defection in the late phase.

Clinical features of immune-mediated hepatotoxicity induced by immune checkpoint inhibitors in patients with cancers.

Purpose: The risk factors and clinical characteristics of ICI-induced immune-mediated hepatotoxicity (IMH) are not fully understood. Thus, the present study sought to clarify the clinical features of IMH.

Methods: All patients treated with ICIs between September 2014 and April 2019 at our institution were included.

Liver abscess caused by Cutibacterium namnetense after transarterial chemoembolization for hepatocellular carcinoma.

A 72-year-old man underwent transarterial chemoembolization (TACE) for solitary hepatocellular carcinoma (HCC) located on the S6 segment. He had a history of anti-viral therapy for hepatitis C virus and was being treated for diabetes mellitus with inadequate control. On day 28 after TACE, he visited our hospital again, with complaints of fever and abdominal pain in the right upper quadrant.

Quasispecies variant of pre-S/S gene in HBV-related hepatocellular carcinoma with HBs antigen positive and occult infection.

Background: Hepatocellular carcinoma (HCC) can develop in patients who are negative for the hepatitis B surface antigen (HBsAg) in serum but positive for hepatitis B virus (HBV) DNA in the liver, referred to as occult HBV infection (OBI). Previous reports showed that HBV variants in OBI-related HCC are different from those in HBsAg-positive HCC. In the present study, HBV quasispecies based on the pre-S/S gene in OBI-related HCC patients were examined by high throughput sequencing and compared with those in HBsAg-positive HCC.

Factors associated with the decrease in hepatitis B surface antigen titers following interferon therapy in patients with chronic hepatitis B: Is interferon and adefovir combination therapy effective?

The purpose of antiviral therapy in chronic hepatitis B (CHB) is generally to achieve a decrease and ultimately disappearance of HBs antigen (HBsAg). Interferon (IFN) therapy of CHB appears to be less effective in Asian countries than in European countries, and the advantage of IFN and nucleotide(s) analog (NA) combination therapy has yet to be fully investigated. The present study focused on the factors associated with a decrease in HBs antigen following IFN monotherapy or IFN + NA combination therapy.

Mutational diversity of NS5A and NS3 during triple therapy (telaprevir, pegylated-interferon-α 2b and ribavirin) for genotype 1b chronic hepatitis C: The Kobe Hepatitis Therapeutic Group.

Telaprevir, a non-structural (NS)3/4A protease inhibitor, is a direct-acting antiviral drug that inhibits viral replication. Triple therapy with telaprevir, pegylated interferon, and ribavirin is a standard therapeutic regimen for patients with genotype 1b chronic hepatitis C virus (HCV) infection and a high viral load. Several factors, including mutations in the NS5A gene, are important predictors of the efficacy of interferon therapy.
