Single-cell RNA seq-derived signatures define response patterns to atezolizumab + bevacizumab in advanced hepatocellular carcinoma.

Background & Aims: The combination of atezolizumab and bevacizumab (atezo+bev) is the current standard of care for advanced hepatocellular carcinoma (HCC), providing a median overall survival (OS) of 19.2 months. Here, we aim to uncover the underlying cellular processes driving clinical benefit versus resistance to atezo+bev.

Efficacy and Safety of Atezolizumab plus Bevacizumab versus Sorafenib in Hepatocellular Carcinoma with Main Trunk and/or Contralateral Portal Vein Invasion in IMbrave150.

Introduction: Atezolizumab plus bevacizumab significantly improved overall survival (OS) and progression-free survival (PFS) versus sorafenib in patients with unresectable hepatocellular carcinoma (HCC) in IMbrave150. Efficacy and safety in patient subpopulations with Vp4 portal vein tumor thrombosis (PVTT) and other high-risk prognostic factors are reported.

Methods: IMbrave150 was a global, randomized (2:1), open-label, phase 3 study in systemic treatment-naive patients with unresectable HCC; OS and PFS were co-primary endpoints.

Neutralizing GDF-15 can overcome anti-PD-1 and anti-PD-L1 resistance in solid tumours.

Cancer immunotherapies with antibodies blocking immune checkpoint molecules are clinically active across multiple cancer entities and have markedly improved cancer treatment. Yet, response rates are still limited, and tumour progression commonly occurs. Soluble and cell-bound factors in the tumour microenvironment negatively affect cancer immunity.

Blocking interleukin-1 receptor type 1 (IL-1R1) signaling in hepatocytes slows down diethylnitrosamine-induced liver tumor growth in obese mice.

Background: An increasing number of HCC develops in the context of metabolic dysfunction-associated steatotic liver disease and its inflammatory form, metabolic dysfunction-associated steatohepatitis, even in the absence of cirrhosis. Chronic metabolic inflammation is the driving force of metabolic dysfunction-associated steatotic liver disease progression and a key factor in hepatocarcinogenesis. Given the prominent role of IL-1 signaling in inflammation and metabolic diseases, we investigated the relevance of the hepatocyte-specific IL-1 receptor type 1 knockout in metabolic dysfunction-associated steatohepatitis-related noncirrhotic HCC.

Different risk and protective factors predict change of planning ability in middle versus older age.

Age-related cognitive decline has become an increasingly relevant public health issue. However, risk and protective factors of cognitive decline have yet to be investigated prospectively taking into account genetic, lifestyle, physical and mental health factors. Population-based data from middle-aged (40 to 59 years; N = 2,764) and older individuals (60 to 80 years; N = 1,254) were drawn from a prospective community cohort study using the Tower of London (TOL) planning task.

Inflammation in liver fibrosis and atrial fibrillation: A prospective population-based proteomic study.

Background & Aims: Elevated liver stiffness has been associated with atrial fibrillation (AFib) in the general population. The mechanism underlying this association is unclear.

Methods: Participants were recruited from the general population and prospectively enrolled with follow-up for 5 years.

Impairment of health-related quality of life among people with type 2 diabetes and advanced liver fibrosis.

People with type 2 diabetes mellitus (T2DM) show a high prevalence of steatotic liver disease (SLD), and especially metabolic dysfunction-associated steatotic liver disease (MASLD), with liver fibrosis. Their health-related quality of life (HRQL) is affected by multiple in part overlapping factors and aggravated by metabolic and liver-related comorbidities, including liver fibrosis stage. The aim of this study was to investigate the effect size of advanced fibrosis (AF) on the HRQL in people with T2DM.

Evaluation of Sonographic Muscle Measurement Using Established Muscle Markers.

Objectives: Loss of muscle quantity and function is associated with frailty and reduced quality of life. Sonography is a simple option to quantify muscle mass, which could be included into routine diagnostic workup. This study was designed to prospectively evaluate sonographic measurement and to compare it with established measurements of muscle quantity and function.

Impact of Bevacizumab Being Skipped due to Adverse Events of Special Interest for Bevacizumab in Patients with Unresectable Hepatocellular Carcinoma Treated with Atezolizumab plus Bevacizumab: An Exploratory Analysis of the Phase III IMbrave150 Study.

Introduction: The phase III IMbrave150 study established atezolizumab + bevacizumab as the global standard of care in patients with unresectable hepatocellular carcinoma (HCC). This exploratory analysis examined the impact of bevacizumab interruption due to bevacizumab adverse events of special interest (AESIs).

Methods: Patients in IMbrave150 who were randomized to atezolizumab + bevacizumab and received treatment for ≥6 months (to reduce immortal time bias) were included in group A-1 if bevacizumab had ever been skipped due to bevacizumab AESIs or to group A-2 otherwise.

Proton pump inhibitor use and risk of hepatic encephalopathy: A multicentre study.

Background & Aims: Data on the association between proton pump inhibitor (PPI) use and hepatic encephalopathy (HE) are conflicting, and data from multicentre studies are scarce. The aim of this study was to dissect the potential association between PPI use and minimal (MHE) and overt HE (OHE).

Methods: Data from patients with cirrhosis recruited at seven centres across Europe and the US were analysed.

Immunotherapy vs Best Supportive Care for Patients With Hepatocellular Cancer With Child-Pugh B Dysfunction.

Importance: Whether patients with Child-Pugh class B (CP-B) cancer with unresectable hepatocellular carcinoma (uHCC) benefit from active anticancer treatment vs best supportive care (BSC) is debated.

Objective: To evaluate the association of immune checkpoint inhibitor (ICI)-based therapies vs BSC with overall survival (OS) of patients with uHCC and CP-B liver dysfunction.

Design, Setting, And Participants: This retrospective, multicenter, international clinical case series examined data of patients with CP-B with uHCC who were receiving first-line ICI-based regimens from September 2017 to December 2022 whose data were extracted from an international consortium and compared with a cohort of patients with CP-B receiving BSC.

Amount of ascites impacts survival in patients with hepatocellular carcinoma undergoing transarterial chemoembolization advocating for volumetric assessment.

Preliminary work has shown that portal hypertension plays a key role for the prognosis in patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE). Specifically, the presence of ascites appears to be a strong negative predictor for these patients. However, it remains unclear whether different ascites volumes influence prognosis.

PARP-1 selectively impairs -driven phenotypic and molecular features in intrahepatic cholangiocarcinoma.

Objective: Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver cancer with limited therapeutic options. mutations are among the most abundant genetic alterations in iCCA associated with poor clinical outcome and treatment response. Recent findings indicate that Poly(ADP-ribose)polymerase1 (PARP-1) is implicated in -driven cancers, but its exact role in cholangiocarcinogenesis remains undefined.

Patient-Reported Outcomes From the Phase III HIMALAYA Study of Tremelimumab Plus Durvalumab in Unresectable Hepatocellular Carcinoma.

Purpose: In the phase III HIMALAYA study (ClinicalTrials.gov identifier: NCT03298451) in unresectable hepatocellular carcinoma (uHCC), the Single Tremelimumab Regular Interval Durvalumab (STRIDE) regimen significantly improved overall survival versus sorafenib, and durvalumab monotherapy was noninferior to sorafenib. Patient-reported outcomes (PROs), a secondary outcome from HIMALAYA, are reported here.

PHOCUS: A Phase 3, Randomized, Open-Label Study of Sequential Treatment with Pexa-Vec (JX-594) and Sorafenib in Patients with Advanced Hepatocellular Carcinoma.

Introduction: Intratumoral administration of pexa-vec (pexastimogene devacirepvec), an oncolytic and immunotherapeutic vaccinia virus, given to patients with hepatocellular carcinoma (HCC), is associated with both local and distant tumor responses. We hypothesized subsequent treatment with sorafenib could demonstrate superior efficacy.

Methods: This random phase III open-label study evaluated the sequential treatment with pexa-vec followed by sorafenib compared to sorafenib in patients with advanced HCC and no prior systemic treatment.

Lower uromodulin serum levels are associated with poorer prognosis in patients with cirrhosis and hepatorenal syndrome type 2.

Hepatorenal syndrome (HRS) is associated with a dismal prognosis in patients with cirrhosis, and therapeutic options are limited. Biomarkers to identify patients with poor response to therapy are urgently needed. This study aimed to evaluate the predictive value of serum levels of uromodulin (sUMOD) in patients with cirrhosis and HRS treated with terlipressin and albumin (T/A).

Short-term reduction of dietary gluten improves metabolic-dysfunction associated steatotic liver disease: A randomised, controlled proof-of-concept study.

Background: The current management of metabolic dysfunction-associated steatotic liver disease (MASLD) relies on lifestyle intervention. Prior studies have shown that nutritional wheat amylase trypsin inhibitors (ATI) activate toll-like receptor 4 on intestinal myeloid cells to enhance intestinal and extra-intestinal inflammation, including the promotion of murine MASLD, insulin resistance and liver fibrosis.

Aims: We aimed to assess the impact of ATI (gluten)-free diet in liver as well as metabolic parameters of biopsy-proven MASLD patients.

A meta-analysis and real-world cohort study on the sex-related differences in efficacy and safety of immunotherapy for hepatocellular carcinoma.

Background & Aims: Sex-related differences in the immune pathogenesis of hepatocellular carcinoma (HCC), particularly related to oestrogen-dependent secretion of pro-tumourigenic cytokines, are well-known. Whether sex influences the efficacy and safety of immunotherapy is not known.

Methods: We performed a restricted maximum likelihood random effects meta-analysis of five phase III trials that evaluated immune checkpoint inhibitors (ICIs) in advanced HCC and reported overall survival (OS) hazard ratios (HRs) stratified by sex to evaluate sex-related differences in OS.

N-cadherin: A diagnostic marker to help discriminate primary liver carcinomas from extrahepatic carcinomas.

Distinguishing primary liver cancer (PLC), namely hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA), from liver metastases is of crucial clinical importance. Histopathology remains the gold standard, but differential diagnosis may be challenging. While absent in most epithelial, the expression of the adherens junction glycoprotein N-cadherin is commonly restricted to neural and mesenchymal cells, or carcinoma cells that undergo the phenomenon of epithelial-to-mesenchymal transition (EMT).

Obesity and harmful alcohol consumption are predictors for advanced liver disease in the disease management program for type 2 diabetes.

Background: Type 2 diabetes mellitus (T2DM) is a major risk factor for advanced liver disease. The aim of this prospective cohort study was to assess the prevalence and associated risk factors of liver fibrosis and cirrhosis in primary care centers participating in the diabetes disease management program (DMP) in Germany.

Methods: A total of 175 participants with the diagnosis of T2DM were enrolled in two primary care centers.
