The most effective treatment of hepatocellular carcinoma is surgical removal of the tumour but there is often recurrence. In this large international study, we develop a statistical method that allows clinicians to estimate the risk of recurrence in an individual patient. This facility enhances communication with the patient about the likely success of the treatment and will help in designing clinical trials that aim to find drugs that decrease the risk of recurrence.

The PNI is a significant prognostic factor for OS and DFS of patients with very early/early stage HCC receiving curative surgery.

Nonalcoholic fatty liver disease (NAFLD)-induced hepatocellular carcinoma (HCC) is an emerging malignancy in the developed world; however, mechanisms that contribute to its formation are largely unknown, and targeted therapy is currently not available. Our RNA sequencing analysis of NAFLD-HCC samples revealed squalene epoxidase () as the top outlier metabolic gene overexpressed in NAFLD-HCC patients. Hepatocyte-specific transgenic expression in mice accelerated the development of high-fat, high-cholesterol diet-induced HCC. exerts its oncogenic effect via its metabolites, cholesteryl ester and nicotinamide adenine dinucleotide phosphate (NADP). Increased expression promotes the biosynthesis of cholesteryl ester, which induces NAFLD-HCC cell growth. increased the NADP/NADPH (reduced form of NADP) ratio, which triggered a cascade of events involving oxidative stress-induced DNA methyltransferase 3A (DNMT3A) expression, DNMT3A-mediated epigenetic silencing of PTEN, and activation of AKT-mTOR (mammalian target of rapamycin). In human NAFLD-HCC and HCC, is overexpressed and its expression is associated with poor patient outcomes. Terbinafine, a U.S. Food and Drug Administration-approved antifungal drug targeting, markedly inhibited -induced NAFLD-HCC cell growth in NAFLD-HCC and HCC cells and attenuated tumor development in xenograft models and in transgenic mice. Suppression of tumor growth by terbinafine is associated with decreased cholesteryl ester concentrations, restoration of PTEN expression, and inhibition of AKT-mTOR, consistent with blockade of SQLE function. Collectively, we established as an oncogene in NAFLD-HCC and propose that repurposing SQLE inhibitors may be a promising approach for the prevention and treatment of NAFLD-HCC.

Background:Application of curative therapy for hepatocellular carcinoma is crucially dependent on underlying liver function. Using the recently described ALBI grade we examined the long-term impact of liver dysfunction on survival of early-stage hepatocellular carcinoma (HCC) patients.Methods:This cohort study comprised 2559 HCC patients from different geographic regions, all treated with curative intent. We also examined the relation between indocyanine green (ICG) clearance and ALBI score. Survival was measured from the date of treatment to the date of death or last follow-up.Results:The ALBI score correlated well with ICG clearance. Among those undergoing surgical resection, patients with ALBI grade-1 (good liver function) survived approximately twice as long as those with ALBI grade-2 (less good liver function), although more than 90% of these patients were classified as Child–Pugh (C-P) grade A. In the cohort receiving ablative therapies, there was a similar difference in survival between ALBI grade-1 and grade-2. Cox regression analysis confirmed that the ALBI score along with age, gender, aetiology and tumour factors (AFP, tumour size/number and vascular invasion) independently influenced survival in HCC patients receiving curative treatments.Conclusions:The ALBI score represents a simple approach to the assessment of liver function in patients with HCC. After potentially curative therapy, those with ALBI grade-1 survived approximately twice as long as those with ALBI grade-2. These data suggest that ALBI grade-1 patients are appropriately treated with surgical resection whereas ALBI grade-2 patients may, where the option exists, be more suitable for liver transplantation or the less invasive curative ablative therapies.
