Inflamed and non-inflamed classes of HCC: a revised immunogenomic classification

Conceptual Model for the Hepatocellular Carcinoma Screening Continuum: Current Status and Research Agenda

Amit G. Singal et al.

Summary: Hepatocellular carcinoma (HCC) has a poor prognosis with survival rates below 20% in 5 years, partly due to failures in the cancer screening process continuum. A conceptual model outlining discrete steps in the HCC screening process highlights delays or failures at each step and identifies factors contributing to these failures at the patient, provider, and health care system levels. Comparing HCC screening processes with breast and colorectal cancer screening can help identify opportunities for improvement and ultimately improve early detection of HCC.

Association between ultrasound quality and test performance for HCC surveillance in patients with cirrhosis: a retrospective cohort study

Nicolas Chong et al.

Summary: This study found that impaired ultrasound visualization is associated with worse surveillance test performance in patients with cirrhosis. Severe visual limitations were linked to lower sensitivity, while moderate limitations were associated with an increased risk of false-positive results. Alternative blood-based biomarkers and imaging strategies are needed for patients at risk of ultrasound-based surveillance failure.

Incidence of Hepatocellular Carcinoma in Patients With Nonalcoholic Fatty Liver Disease: A Systematic Review, Meta-analysis, and Meta-regression

Lorenzo A. Orci et al.

Summary: Nonalcoholic fatty liver disease (NAFLD) may be a risk factor for hepatocellular carcinoma (HCC), and this study used meta-analysis to analyze the incidence rates of HCC in NAFLD patients. The results showed that NAFLD patients with cirrhosis have a similar risk of developing HCC compared to cirrhosis patients with other causes. However, the incidence of HCC in nonalcoholic steatohepatitis or simple steatosis patients is lower.

Summary: Patients with NAFLD and diabetes have a high risk of developing HCC. The study found that the use of metformin was associated with a reduced risk of developing HCC, while combination therapy was associated with an increased risk. Glycemic control can be a useful biomarker for stratifying HCC risk in these patients.

HCC surveillance improves early detection, curative treatment receipt, and survival in patients with cirrhosis: A meta-analysis

Amit G. Singal et al.

Summary: In this systematic review and meta-analysis, HCC surveillance was found to be associated with improved early-stage detection, curative treatment receipt, and survival in patients with cirrhosis. However, there was significant heterogeneity in the pooled estimates, and there were fewer data quantifying potential surveillance-related harms. Available data suggest that HCC surveillance is of high value in patients with cirrhosis, although further studies evaluating benefits and harms are still needed.

Summary: NASH has become an important cause of cirrhosis and hepatocellular carcinoma, and there are currently more than 50 therapeutic agents in clinical development. Obeticholic acid has achieved interim histological improvement in fibrosis without worsening NASH in the phase 3 REGENERATE study, and long-term clinical outcomes are being followed.

This has led to a lack of inclusion of NAFLD in national and international strategies and policies for non-communicable diseases, highlighting the need for a more comprehensive public health response to the disease.

Summary: This study found that targeting neutrophils using a CXCR2 small molecule inhibitor can enhance the sensitivity of non-alcoholic steatohepatitis-associated hepatocellular carcinoma (NASH-HCC) to immune checkpoint inhibition therapy (ICI). The combination therapy can reprogram the tumor immune microenvironment, increase the number of anti-tumor immune cells, and improve treatment outcomes.

NAFLD-driven HCC: Safety and efficacy of current and emerging treatment options

Friedrich Foerster et al.

Summary: Given the global increase in obesity and type 2 diabetes, non-alcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are becoming important causes of hepatocellular carcinoma (HCC). HCCs caused by chronic inflammation mediated by lipotoxicity have unique characteristics, such as occurring in up to 50% of NAFLD-HCC patients without cirrhosis and having a lower annual incidence, leading to challenges in surveillance strategies. Locoregional treatments may be equally effective regardless of HCC etiology, but the effectiveness of systemic therapy is less clear. Tyrosine kinase inhibitors are likely equally effective, while there are initial signals that immune checkpoint inhibitors may be less effective in NAFLD-HCC compared to viral HCC.

Summary: Non-alcoholic steatohepatitis (NASH) negatively affects the efficacy of immune checkpoint inhibitor (ICI) therapy in hepatocellular carcinoma (HCC). This study reveals that NASH alters the metabolism, function, and motility of hepatic CD8+ T cells, leading to reduced responsiveness to anti-PD-1 treatment. The efficacy can be rescued by metformin treatment.

Summary: Rifaximin treatment has significant effects on improving hepatic steatosis, lobular inflammation, and fibrogenesis in mice with methionine and choline deficient (MCD) diet-induced non-alcoholic steatohepatitis (NASH). It achieves this by altering the gut microbiome and decreasing levels of deoxycholic acid (DCA) in the ileum. These findings suggest that rifaximin may be a promising approach for NASH therapy in humans.

Cabozantinib plus atezolizumab versus sorafenib for advanced hepatocellular carcinoma (COSMIC-312) : a multicentre, open-label, randomised, phase 3 trial

Robin Kate Kelley et al.

Summary: This study evaluated the combination of cabozantinib and atezolizumab versus sorafenib as first-line systemic treatment for advanced hepatocellular carcinoma. The combination treatment group showed better progression-free survival compared to the sorafenib group, but overall survival did not reach statistical significance. Common adverse events in the combination group included liver enzyme elevation, hypertension, and skin reactions. The study suggests that cabozantinib plus atezolizumab may be a treatment option, but further research is needed.

Patients with high expression of VEGF Receptor 2, regulatory T cells, and myeloid inflammation signatures showed better outcomes with the combination therapy compared to atezolizumab alone. These findings provide insights into baseline immune and genetic features that can identify patients who will benefit from the combination therapy of atezolizumab and bevacizumab in advanced hepatocellular carcinoma.
