Impact of metabolic dysfunction-associated fatty liver disease on liver transplant recipients with hepatitis B virus-related hepatocellular carcinoma. Eur J Clin Nutr 2024; 78:107-113. [PMID: 37935889 DOI: 10.1038/s41430-023-01363-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Revised: 10/07/2023] [Accepted: 10/17/2023] [Indexed: 11/09/2023]
Abstract
BACKGROUND Metabolic dysfunction-associated fatty liver disease was proposed by international consensus to redefine the metabolic abnormal condition. However, its impact on liver transplant recipients with hepatitis B virus-related hepatocellular carcinoma has not been explored. METHODS A two-center retrospective cohort study on liver transplant recipients with hepatitis B virus-related hepatocellular carcinoma was performed to analyze the impact of metabolic dysfunction-associated fatty liver disease on the clinicopathologic parameters and prognosis. RESULTS There were 201 liver transplant recipients enrolled from two hospitals in our study. The pre- and post-transplant prevalences of metabolic dysfunction-associated fatty liver disease were 9.95% and 28.86%, respectively. The clinicopathological parameters revealed a similarity between patients with and without pre-transplant metabolic dysfunction-associated fatty liver disease. In contrast, the group with post-transplant metabolic dysfunction-associated fatty liver disease was linked with older age, a higher hepatitis recurrence rate and incidence of cardiovascular disease, usage of calcineurin inhibitors, a greater body mass index and waist circumference, lower albumin and high-density lipoprotein cholesterol levels, and poorer tumor-free survival and overall survival. The multivariate analysis showed the largest tumor size >4 cm (95% confidence intervals: 0.06~0.63, p = 0.006), microvascular invasion (95% confidence intervals: 1.61~14.92, p = 0.005), post-transplant metabolic dysfunction-associated fatty liver disease (95% confidence intervals: 1.40~10.60, p = 0.009), and calcineurin inhibitors-based regimen (95% confidence intervals: 0.33~0.96, p = 0.036) were the independent risk factors for recurrent hepatocellular carcinoma. CONCLUSIONS Our study suggests that post-transplant metabolic dysfunction-associated fatty liver disease is more closely to metabolic abnormalities and that it can help identify liver transplant recipients at high risk of recurrent hepatocellular carcinoma.

Monocyte-to-High-Density Lipoprotein-Cholesterol Ratio Predicts Prognosis of Hepatocellular Carcinoma in Patients with Metabolic-Associated Fatty Liver Disease. J Hepatocell Carcinoma 2024; 11:145-157. [PMID: 38260867 PMCID: PMC10802127 DOI: 10.2147/jhc.s439397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 01/13/2024] [Indexed: 01/24/2024] Open
Abstract
Purpose The incidence of non-B and non-C hepatocellular carcinoma (NBNC-HCC) is increasing globally. Metabolically associated fatty liver disease (MAFLD) has been a contributing factor to this rising trend in NBNC-HCC incidence. The monocyte-to-high-density lipoprotein-cholesterol ratio (MHR) is a new prognostic marker that connects systemic inflammation with disorders of lipid metabolism. Therefore, MHR may be a potential prognostic predictor of patients with MAFLD-related HCC (MAFLD-HCC). This study aims to investigate the relationship between the MHR and prognosis of patients with MAFLD-HCC and construct a novel prognostic prediction tool for MAFLD-HCC. Patients and Methods This retrospective study of patients with MAFLD-HCC included training (n = 112) and internal validation (n = 37) cohorts. Univariate and multivariate Cox proportional hazard regression analysis was conducted to identify independent risk factors of survival. A visual nomogram was constructed to assess the performance of the two groups. Furthermore, receiver operating characteristic (ROC) curves and calibration curves were used to verify the prognostic discriminative ability of this nomogram, even in the MHR, ALBI grade, and MHR-ALBI model. Results Univariate and multivariate analyses revealed that extrahepatic metastases, Vascular invasion, Barcelona staging B, C, D, elevated ALBI Grade 3, C-reactive protein (CRP), and MHR were independent risk factors for the prognosis of MAFLD-HCC. Moreover, calibration plots showed good discrimination and consistency when the significant factors were entered into the nomogram. Meanwhile, the MHR strongly correlated with the prognosis of cancer under a background of MAFLD-HCC, with a sensitivity of 88.89% and a specificity of 79.61%. Importantly, the performance of the MHR alone (AUC = 86.2) was not only superior to the ALBI grade (AUC = 63.8) but was comparable to the combination of MHR and ALBI (AUC = 88.5). Conclusion The novel nomogram demonstrated good value in predicting the overall survival of patients with MAFLD-HCC. The MHR may be a potential predictor of prognosis.

Abstract
Hepatocellular carcinoma has a substantial global mortality burden which is rising despite advancements in tackling the traditional viral risk factors. Metabolic (dysfunction) associated fatty liver disease (MAFLD) is the most prevalent liver disease, increasing in parallel with the epidemics of obesity, diabetes and systemic metabolic dysregulation. MAFLD is a major factor behind this sustained rise in HCC incidence, both as a single disease entity and often via synergistic interactions with other liver diseases. Mechanisms behind MAFLD-related HCC are complex but is crucially underpinned by systemic metabolic dysregulation with variable contributions from interacting disease modifiers related to environment, genetics, dysbiosis and immune dysregulation. MAFLD-related HCC has a distinct clinical presentation, most notably its common occurrence in non-cirrhotic liver disease. This is just one of several major challenges to effective surveillance programmes. The response of MAFLD-related HCC to immune-checkpoint therapy is currently controversial, and is further complicated by the high prevalence of MAFLD in individuals with HCC from viral aetiologies. In this review, we highlight the current data on epidemiology, clinical characteristics, outcomes and screening controversies. In addition, concepts that have arisen because of the MAFLD paradigm such as HCC in MAFLD/NAFLD non-overlapping groups, dual aetiology tumours and MAFLD sub-phenotypes is reviewed.

Abstract
An international panel recently proposed an update to the terminology and diagnostic criteria for fatty liver disease. The experts proposed a change in the nomenclature from non-alcoholic fatty liver disease (NAFLD) to metabolic (dysfunction)-associated fatty liver disease (MAFLD). This single-letter change, we believe, heralds the dawn of a new era in clinical practice and in clinical and basic research as well. The new nomenclature with the easily applicable approach has stimulated the enthusiasm of the researchers worldwide, resulting in a large number of publications over the past two years. Several recent studies have provided tremendous evidence of the superiority of the MAFLD criteria over the NAFLD criteria. Many studies in different geographic areas of the world including the United States, Europe, and Asia on a large number of patients proved that the utility of MAFLD criteria was higher than that of the NAFLD criteria in different aspects of fatty liver diseases. Consequently, many societies, physician and nurse groups, health stakeholders, representatives of regulatory sciences, and others endorsed the new nomenclature. Here we highlight the endorsement of the new name by different societies and groups and the outcome of different studies on the new nomenclature in addition to a short discussion of the debate by some experts.

Abstract
Background: Hepatocellular carcinoma (HCC) has become the world's primary cause of cancer death. Obesity, hyperglycemia, and dyslipidemia are all illnesses that are part of the metabolic syndrome. In recent years, this risk factor has become increasingly recognized as a contributing factor to HCC. Around the world, non-alcoholic fatty liver disease (NAFLD) is on the rise, especially in western countries. In the past, the exact pathogenesis of NAFLD that progressed to metabolic risk factors (MFRs)-associated HCC has not been fully understood. Methods: Two groups of the GEO dataset (including normal/NAFLD and HCC with MFRs) were used to analyze differential expression. Differentially expressed genes of HCC were verified by overlapping in TCGA. In addition, functional enrichment analysis, modular analysis, Receiver Operating Characteristic (ROC) analysis, LASSO analysis, and Genes with key survival characteristics were analyzed. Results: We identified six hub genes (FABP5, SCD, CCL20, AGPAT9(GPAT3), PLIN1, and IL1RN) that may be closely related to NAFLD and HCC with MFRs. We constructed survival and prognosis gene markers based on FABP5, CCL20, AGPAT9(GPAT3), PLIN1, and IL1RN.This gene signature has shown good diagnostic accuracy in both NAFLD and HCC and in predicting HCC overall survival rates. Conclusion: As a result of the findings of this study, there is some guiding significance for the diagnosis and treatment of liver disease associated with NAFLD progression.

Abstract
AIMS This retrospective study compared the survival between elderly and non-elderly patients. METHODS A total of 5545 treatment-naive patients with hepatocellular carcinoma (HCC) who visited 7 different hospitals from January 2000 to December 2018 were included. Patients ≥80 years old were defined as elderly patients. We divided the patients into three groups based on the timing of the initial treatment: Early, middle, and late periods defined as 2000 to 2005, 2006 to 2012, and 2013 to 2018, respectively. RESULTS There were 132 (8.9%), 405 (17.5%), and 388 (22.2%) elderly patients in the early, middle, and late period, respectively, showing a significant increase over time (p < 0.001). In both elderly and non-elderly patients, the median albumin-bilirubin score significantly improved over time and the diagnosis of HCC was made slightly earlier over time. The median overall survival (OS) in elderly patients was 52.8, 42.0, and 45.6 months in the early, middle, and late period, respectively, without a significant improvement (p = 0.17) whereas the OS in non-elderly patients was significantly improved (p < 0.001). The percentage of elderly patients receiving curative treatments did not significantly increase (p = 0.43), while that of non-elderly patients did (p = 0.017). Non-liver-related death in elderly patients significantly differed among periods (p = 0.023), while liver-related death did not (p = 0.050). Liver- and non-liver-related death in non-elderly patients significantly differed among periods (p < 0.001, p = 0.005). CONCLUSIONS Survival in elderly patients was not improved despite an improvement in their liver function. Curative treatments should be conducted when appropriate after evaluating each elderly patient.
