Delivering adjuvant and neoadjuvant treatments in the early stages of hepatocellular carcinoma.

Introduction: Hepatocellular carcinoma (HCC) presents a formidable challenge in oncology, demanding innovative treatment approaches. Both adjuvant and neoadjuvant therapies, thanks to the introduction of immunotherapy, have emerged as promising strategies in the management of HCC, aiming to reduce the risk of relapse and ultimately to improve survival.

Areas Covered: This review considers current evidence, ongoing clinical trials, and future strategies to elucidate the evolving landscape of neoadjuvant and adjuvant treatments in HCC.

From MASH to HCC: the role of Gas6/TAM receptors.

Metabolic dysfunction-associated steatohepatitis (MASH) is the replacement term for what used to be called nonalcoholic steatohepatitis (NASH). It is characterized by inflammation and injury of the liver in the presence of cardiometabolic risk factors and may eventually result in the development of hepatocellular carcinoma (HCC), the most common form of primary liver cancer. Several pathogenic mechanisms are involved in the transition from MASH to HCC, encompassing metabolic injury, inflammation, immune dysregulation and fibrosis.

Mechanisms of Resistance to Immunotherapy in Hepatocellular Carcinoma.

Systemic treatment for advanced hepatocellular carcinoma (HCC) has been revolutionized over the last few years following the approval of immune checkpoint inhibitors (ICI). Despite the promising survival extension seen with ICI combination regimens, responses are not universally seen and the optimal partner for programmed cell death 1 pathway inhibitors remains to be identified. Even fewer encouraging results have been demonstrated with ICI used for monotherapy.

Role of Etiology in Hepatocellular Carcinoma Patients Treated with Lenvatinib: A Counterfactual Event-Based Mediation Analysis.

Background: Whether the etiology of underlying liver disease represents a prognostic factor in patients with hepatocellular carcinoma (HCC) treated with lenvatinib is still a matter of debate. This study investigates whether the viral etiology of HCC plays a prognostic role in overall survival (OS). Methods: Data derived from a multicenter series of 313 HCC patients treated with lenvatinib between 2019 and 2022 were analyzed.

Identification of the Best Cut-Off Value of PIVKA-II for the Surveillance of Patients at Risk of Hepatocellular Carcinoma Development.

Patients with cirrhosis are at risk of hepatocellular carcinoma (HCC) development and, according to current guidelines, should undergo surveillance by ultrasound at six month intervals. Due to the known limitations of surveillance strategies based on ultrasonography, the use of tumor biomarkers, although debated, is common practice in many centers. The aim of the study was to identify the best cut-off value for one of such biomarkers, protein induced by vitamin K absence, or antagonist-II (PIVKA-II).

17β-Oestradiol Protects from Hepatitis C Virus Infection through Induction of Type I Interferon.

Background And Aims: Sex hormones are widely recognised to act as protective factors against several viral infections. Specifically, females infected by the hepatitis C virus display higher clearance rates and reduced disease progression than those found in males. Through modulation of particle release and spread, 17β-oestradiol controls HCV's life cycle.

HSD17B13 and other liver fat-modulating genes predict development of hepatocellular carcinoma among HCV-positive cirrhotics with and without viral clearance after DAA treatment.

Background: Genetic predisposition to accumulate liver fat (expressed by a polygenic risk score, GRS, based on the number of at-risk alleles of PNPLA3, TM6SF2, MBOAT7 and GCKR) may influence the probability of developing hepatocellular carcinoma (HCC) after hepatitis C treatment. Whether this holds true taking into account carriage of the HSD17B13:TA splice variant, also affecting lipogenesis, and achievement of viral clearance (SVR), is unknown.

Methods: PNPLA3, TM6SF2, MBOAT7, GCKR and HSD17B13 variants were determined in a cohort of 328 cirrhotic patients free of HCC before starting treatment with direct acting antivirals (DAA).

Radioembolization vs sorafenib in locally advanced hepatocellular carcinoma with portal vein tumor thrombosis: A propensity score and Bayesian analysis.

Objective: In this study we aimed to compare patient outcomes between the use of transarterial radioembolization (TARE) and sorafenib in patients with hepatocellular carcinoma (HCC) and intrahepatic portal vein tumor thrombosis (PVTT).

Methods: A total of 65 patients with HCC and intrahepatic PVTT treated in five Italian hospitals between 2012 and 2018 were included in the analysis. Those with any previous treatment, extension of PVTT to the main portal tract and extrahepatic involvement were excluded.

Direct antivirals and cognitive impairment in hepatitis C: a clinical-neurophysiologic study.

Cognition was assessed in hepatitis C virus (HCV) patients, who did not meet the criteria for a minimal hepatic encephalopathy. Their liver function was compensated. We then disentangled potential cognitive changes associated with a sustained virologic response at 12 weeks (SVR-12), following treatment with direct antiviral agents (DAAs).

Liver Stiffness, Not Fat Liver Content, Predicts the Length of QTc Interval in Patients with Chronic Liver Disease.

The severity of fatty liver at ultrasound has been associated with QT length, a finding invoked to explain the excess cardiovascular risk of patients with fatty liver. However, the ability of ultrasound to stage accurately the severity of fatty liver is limited, with fibrosis a major confounder. Here, we aimed to verify the alleged relationship between fat liver content and QT length using a technique apt at discriminating steatosis from fibrosis noninvasively, i.

Red Cell Distribution Width and Platelet Count as Biomarkers of Pulmonary Arterial Hypertension in Patients with Connective Tissue Disorders.

Introduction/objective: In the present paper, we aimed to test the value of the red cell distribution width (RDW) coefficient of variation as a candidate biomarker for pulmonary arterial hypertension (PAH) in patients with connective tissue disorders (CTD), correlating it with the degree of cardiopulmonary impairment in these patients.

Methods: The study population included = 141 patients with CTD and = 59 patients affected by pulmonary hypertension of other etiologies, all referred to the Pulmonary Hypertension Clinic of the Cardiology Division of an Academic Hospital in Northern Italy for evaluation (including right catheterization). Clinical, instrumental, and laboratory data were collected and related to RDW and other full blood count indexes.

Identification of mutations in circulating cell-free tumour DNA as a biomarker in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is increasing globally. Prognostic biomarkers are urgently needed to guide treatment and reduce mortality. Tumour-derived circulating cell-free DNA (ctDNA) is a novel, minimally invasive means of determining genetic alterations in cancer.

B2-Lymphocyte responses to oxidative stress-derived antigens contribute to the evolution of nonalcoholic fatty liver disease (NAFLD).

Recent evidence implicates adaptive immunity as a key player in the mechanisms supporting hepatic inflammation during the progression of nonalcoholic fatty liver disease (NAFLD). In these settings, patients with NAFLD often show an increase in the circulating levels of antibodies against oxidative stress-derived epitopes (OSE). Nonetheless, the actual role of humoral immunity in NAFLD is still unclear.

Treatment Stage Migration Maximizes Survival Outcomes in Patients with Hepatocellular Carcinoma Treated with Sorafenib: An Observational Study.

Background: Level I evidence supports the use of sorafenib in patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma, where heterogeneity in efficacy exists due to varying clinicopathologic features of the disease.

Aim: We evaluated whether prior treatment with curative or locoregional therapies influences sorafenib-specific survival.

Methods: From a prospective data set of 785 consecutive patients from international specialist centres, 264 patients (34%) were treatment naïve (TN) and 521 (66%) were pre-treated (PT), most frequently with transarterial chemoembolization ( = 413; 79%).

Cardiac dysfunction as an early predictor of portal hypertension in chronic hepatitis C.

Background: Cirrhotic cardiomyopathy is characterized by a set of cardiovascular modifications observed in advanced chronic liver disease. The aim of this study was to investigate cardiovascular alterations in chronic liver disease with different stages of fibrosis and to correlate cardiac involvement with endoscopic complications of portal hypertension.

Methods: Seventy patients with chronic hepatitis C-related chronic liver disease and 20 sex- and age-matched controls underwent clinical evaluation, hepatic transient elastography, and echocardiography.

17,β-estradiol inhibits hepatitis C virus mainly by interference with the release phase of its life cycle.

Background & Aims: Oestrogen and oestrogen-mediated signalling protect from hepatitis C virus through incompletely understood mechanisms. We aimed to ascertain which phase(s) of hepatitis C virus life cycle is/are affected by oestrogens.

Methods: Huh7 cells infected with the JFH1 virus (genotype 2a) were exposed to dehydroepiandrosterone, testosterone, progesterone and 17β-estradiol (tested with/without its receptor antagonist fulvestrant).

The ALBI grade provides objective hepatic reserve estimation across each BCLC stage of hepatocellular carcinoma.

Background & Aims: Overall survival (OS) is a composite clinical endpoint in hepatocellular carcinoma (HCC) due to the mutual influence of cirrhosis and active malignancy in dictating patient's mortality. The ALBI grade is a recently described index of liver dysfunction in hepatocellular carcinoma, based solely on albumin and bilirubin levels. Whilst accurate, this score lacks cross-validation, especially in intermediate stage HCC, where OS is highly heterogeneous.
