NT-proBNP predicts the development of acute-on-chronic liver failure and mortality in patients with cirrhosis listed for liver transplantation.

Acute-on-chronic liver failure (ACLF) is a major clinical event in cirrhosis that is characterized by high mortality rates and a short window for liver transplantation. N-terminal pro-B-type natriuretic peptide (NT-proBNP) has been suggested as a prognostic biomarker in cirrhosis. However, its accuracy in predicting the development of ACLF or mortality in candidates for liver transplantation remains unknown.

Hepatic Encephalopathy and MELD-Na Predict Treatment Benefit in Autoimmune Hepatitis-related Decompensated Cirrhosis.

Background & Aims: Management of patients with autoimmune hepatitis (AIH)-related decompensated cirrhosis is challenging because of the risk of treatment-related complications and lack of clinical recommendations. We investigated the predictive factors for treatment benefit in AIH-related decompensated cirrhosis at diagnosis and developed an algorithm to guide treatment decisions in clinical practice.

Methods: This retrospective, international, multicenter study included 232 patients with histologically confirmed AIH-related decompensated cirrhosis at diagnosis.

Liver transplantation (LT) remains one of the most effective treatments for hepatocellular carcinoma (HCC) and significantly enhances patient survival. However, the application of LT for HCC faces challenges owing to advancements in cancer-specific treatment modalities and the increased burden of patients' comorbidities. This narrative review explores current controversies and advancements in LT for HCC.

Integrating Molecular Insights into Biliary Tract Cancer Management: A Review of Personalized Therapeutic Strategies.

Biliary tract cancers (BTCs) are rare and aggressive malignancies with an increasing incidence and poor prognosis. The standard systemic treatment for BTCs has evolved to include immune checkpoint inhibitors associated with gemcitabine-cisplatin as first-line therapies. However, survival rates remain low, highlighting the critical need for personalized treatment strategies based on molecular profiling.

Histological predictors of aggressive recurrence of hepatocellular carcinoma after liver resection.

Background & Aims: Assessment of recurrence risk after liver resection (LR) is critical in hepatocellular carcinoma (HCC), particularly with the advent of effective adjuvant therapy. The aim of this study was to analyze the clinical and pathological factors associated with recurrence, aggressive recurrence, and survival after LR.

Method: We performed a retrospective study in which all single HCC (BCLC-0/A) patients treated with LR between February 2000 and November 2020 were included.

Evaluation of Overall Survival by Restricted Mean Survival Time of Advanced Biliary Tract Cancer treated with Immunotherapy: A Systematic Review and Meta-Analysis.

Background: For biliary tract cancer (BTC), the addition of immunotherapy (durvalumab or pembrolizumab) to gemcitabine and cisplatin (GemCis) significantly improved overall survival (OS) in phase 3 clinical trials (RCTs). However, the interpretation and magnitude of the treatment effect is challenging because OS Kaplan-Meier curves violate the proportional hazards (PH) assumption. Analysis using restricted mean survival time (RMST) allows quantification of the benefits in the absence of PH.

Enhancing ACLF prediction by integrating sarcopenia assessment and frailty in liver transplant candidates on the waiting list.

Background & Aims: Malnutrition, sarcopenia, and frailty are prevalent in cirrhosis. We aimed to assess the correlation between assessment tools for malnutrition, sarcopenia, and frailty in patients on the liver transplant (LT) waiting list (WL), and to identify a predictive model for acute-on-chronic liver failure (ACLF) development.

Methods: This prospective single-center study enrolled consecutive patients with cirrhosis on the WL for LT (May 2019-November 2021).

From evidence to clinical practice: Bridging the gap of new liver cancer therapies in Latin America.

The most common primary liver tumors are hepatocellular carcinoma and cholangiocarcinoma. They constitute the sixth most common neoplasia and the third cause of cancer-related deaths worldwide. Although both tumors may share etiologic factors, diagnosis, prognostic factors, and treatments, they differ substantially in determining distinctive clinical management.

Evaluation of the humoral response to the third dose of SARS-COV-2 vaccines in liver transplant recipients.

Solid organ transplant recipients (SOTR) commonly develop an unsatisfactory humoral response to vaccines compared to immunocompetent individuals (IC). We have previously evaluated the humoral response in liver transplant recipients (LTR) who received two-dose vaccines against SARS-CoV-2 and reported that 38 % of LTR did not produce anti-Spike antibodies. Thus, we set out to evaluate the humoral response after the third dose of SARS-CoV-2 vaccines.

Risk of Treatment Failure and Death after Ablation in Hepatocellular Carcinoma Patients-A Multiparametric Prediction.

Background: Ablation is a first-line treatment for Barcelona Clinic Liver Cancer (BCLC)-0/A hepatocellular carcinoma (HCC). However, there are scarce data about patients' outcomes after recurrence. The present study evaluates the impact of patient and tumor characteristics at baseline and at recurrence on the Clinical Decision-Making process.

New Challenges in the Management of Cholangiocarcinoma: The Role of Liver Transplantation, Locoregional Therapies, and Systemic Therapy.

Cholangiocarcinoma (CCA) is a neoplasm with high mortality that represents 15% of all primary liver tumors. Its worldwide incidence is on the rise, and despite important advances in the knowledge of molecular mechanisms, diagnosis, and treatment, overall survival has not substantially improved in the last decade. Surgical resection remains the cornerstone therapy for CCA.

Outcome of patients with HCC and liver dysfunction under immunotherapy: a systematic review and meta-analysis.

Background And Aims: Immunotherapy-based regimes have changed the management of HCC. However, evidence of efficacy in patients with impaired liver function is unknown. This systematic review and meta-analysis assesses survival of HCC patients and liver dysfunction treated with immunotherapy-based regimens.

[Epidemiology of patients with hepatocellular carcinoma in a University hospital].

Hepatocellular carcinoma is the most common primary liver tumor, with 905 677 diagnosed cases and 830 180 deaths, in 2020 worldwide. In Argentina, it accounts for the 9th cause of death for cancer in men and the 10th in women. Unlike other highly-prevalent tumors, scientific evidence for most therapeutic options is limited mainly to small cohorts and retrospective studies.

Non-invasive tests for clinically significant portal hypertension after HCV cure.

Background & Aims: Non-invasive tests (NITs) for clinically significant portal hypertension (CSPH; hepatic venous pressure gradient [HVPG] ≥10 mmHg) have predominantly been studied in patients with active HCV infection. Investigations after HCV cure are limited and have yielded conflicting results. We conducted a pooled analysis to determine the diagnostic/prognostic utility of liver stiffness measurement (LSM)/platelet count (PLT) in this setting.

Heterologous adenovirus-vector/messenger RNA regimen is associated with improved severe acute respiratory syndrome coronavirus 2 humoral response in liver transplant recipients.

Knowledge of the immunogenicity of vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in liver transplant recipients (LTRs) is mainly limited to messenger RNA (mRNA)-based types. We aimed to evaluate the humoral response in LTRs and to address the use of different doses of mycophenolate (MMF) on the probability of developing anti-spike immunoglobulin G (IgG). In this prospective cohort study, SARS-CoV-2 anti-spike IgG, neutralizing antibodies (NAs), and nucleocapsid protein (N) were evaluated in LTRs and healthy volunteers 21-90 days after receiving the second vaccine dose of either ChAdOx1 (AstraZeneca), rAd26-rAd5 (Sputnik V), inactivated BBIBP-CorV (Sinopharm), or the heterologous combination rAd26/mRNA-1273 (Sputnik V/Moderna).

Sarcopenia HIBA score predicts sarcopenia and mortality in patients on the liver transplant waiting list.

Sarcopenia is a prevalent condition that predicts prognosis in patients awaiting liver transplantation (LT). The gold standard for the diagnosis of sarcopenia is the assessment of the muscular area at L3 with computed tomography (CT) scan (skeletal muscle index [SMI]), but the routine use of CT scan is limited in clinical practice. Thus, we designed a single-center observational study aimed to evaluate the clinical factors associated with the presence of sarcopenia by SMI, and to build a score capable of predicting or excluding the presence of sarcopenia in patients on the LT waiting list (WL).
