These features profoundly affect surveillance strategies, which have largely been based on cirrhosis-driven eligibility criteria. This review summarizes current evidence on hepatocellular carcinoma risk in MASLD, with a focus on surveillance. We discuss the epidemiology of MASLD-related hepatocellular carcinoma, the clinical relevance of non-cirrhotic disease, and the limitations of current surveillance approaches, particularly in individuals with obesity and hepatic steatosis. Across international guidelines, routine surveillance is recommended for patients with MASLD-related cirrhosis, whereas surveillance in non-cirrhotic MASLD is generally not advised because of the absence of validated selection criteria. Recent epidemiological and real-world data highlight the marked heterogeneity of HCC risk in MASLD populations and the suboptimal performance of ultrasound-based surveillance strategies.

Although extensively studied in cancer and autoimmune diseases, growing evidence points to a critical role for CD38 in both normal and diseased liver physiology. In hepatic tissue, CD38 is expressed on multiple cell types. Aberrant CD38 activity contributes to increased oxidative stress, inflammation, and diminished tissue repair. Recent studies suggest that CD38 may also promote cellular senescence partly through its regulation of intracellular NAD⁺ and calcium. This review examines the role of CD38 in maintaining hepatic homeostasis and explores its involvement in liver injury, chronic liver diseases, and carcinogenesis. We also highlight the contribution of CD38-mediated signaling to hepatic fibrogenesis and end-stage liver failure as well as its potential role in liver transplantation, particularly post-transplant related conditions including ischemic injury and acute cellular rejection. Given its impact on multiple intracellular processes, CD38 has emerged as a promising therapeutic target. New findings describe how CD38 inhibition preserves NAD⁺ levels, supports tissue recovery, and mitigates disease progression in the liver.

The strongest causal signal emerged in paediatric acute lymphoblastic leukaemia maintenance, where randomised comparisons showed excess hepatic vascular injury, predominantly SOS and portal hypertension phenotypes, with 6-TG versus 6-MP, prompting protocol amendments and limiting prolonged 6-TG use. Outside haematology, evidence for AZA/6-MP associated PSVD and related vascular lesions came mainly from observational cohorts and case reports. PSVD presented insidiously with preserved synthetic function; early clues included unexplained thrombocytopenia or splenomegaly, with progression to varices, ascites, portal vein thrombosis, and portal-hypertension complications. Dose/exposure intensity and host susceptibility modified risk, supporting a plausible continuum between acute and chronic phenotypes, although direct evidence of progression from SOS to PSVD remains limited.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Thiopurines cause a spectrum of hepatic microvascular injury. Evidence most strongly implicates 6-TG, whereas evidence for AZA/6-MP-associated PSVD and related vascular lesions is less consistent but relevant.

Although artificial intelligence has shown clinical utility across hepatology, evidence supporting its implementation in Latin America remains limited. We reviewed the AI applications most relevant to regional hepatology, the barriers to adoption, and priorities for safe implementation. We conducted a narrative review based on iterative appraisal of peer-reviewed studies, regional epidemiological reports, and digital health policy documents identified through March 2026. Priority was given to evidence reporting external validation, pragmatic clinical testing, or direct relevance to implementation in regional health systems.

Adoption in Latin America is limited by uneven digital maturity, weak interoperability, scarce local validation, regulatory fragmentation, and insufficient workforce preparation.

Staging was in accordance with the Barcelona Clinic Liver Cancer (BCLC) 2022 classification.</p><p><strong>Results: </strong>A total of 619 patients (79% male; median age 71 years) were included. Cirrhosis was registered in 65%. BCLC stage distribution was 11% BCLC-0, 53% BCLC-A, 14% BCLC-B, 18% BCLC-C, 2.9% BCLC-D, and 1.1% missing data. First-line therapy was most commonly thermal ablation (TA) in BCLC-0/A (48%), transarterial chemoembolization (TACE) in BCLC-B (46%), and systemic therapy in BCLC-C (41%). Adherence to first-line treatment recommendations was 46% per EASL 2018 and 63% per EASL 2025 guidelines. TACE, transarterial radioembolization and atezolizumab + bevacizumab were applied across all stages, ahead of guideline integration. One-year overall survival was 97% (BCLC-0), 91% (BCLC-A), 79% (BCLC-B), 70% (BCLC-C), and 33% (BCLC-D).</p><p><strong>Conclusion: </strong>Treatment practices in the Netherlands adapt in response to emerging evidence. Guideline-adherent first-line treatment was observed in 46% of patients according to the EASL 2018 guidelines and 63% according to the EASL 2025 guidelines. Although guidelines remain the foundational framework for clinical decision-making, treatment decisions in real-world practice often extend beyond guideline recommendations.</p>","PeriodicalId":7979,"journal":{"name":"Annals of hepatology","volume":" ","pages":"102250"},"PeriodicalIF":6.2,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
