In the 2022 GLOBOCAN report, there were 905 677 new cases of liver cancer (including HCC), with 830 180 deaths due to liver cancer. The incidence is predicted to increase significantly between 2020 and 2040, with 1.4 million new diagnoses expected in 2040 [<span>2</span>]. The management of advanced hepatocellular carcinoma (HCC) in patients with cirrhosis remains a formidable clinical challenge, complicated further by the interplay between tumour burden and liver function. Historically, decompensated cirrhosis was considered a near-absolute contraindication to systemic cancer therapies due to the fragile hepatic reserve and high treatment-related risks. However, systemic therapies for unresectable HCC (uHCC) have advanced from tyrosine kinase inhibitors, such as sorafenib [<span>3</span>] and lenvatinib [<span>4</span>], to immune checkpoint inhibitor (ICI) combinations, such as atezolizumab plus bevacizumab (Atezo-Bev), which have become standard of care [<span>5</span>]. ICIs have become the standard of care. In patients with HCC as opposed to other solid tumours, the underlying hepatic reserve is a crucial determinant of treatment outcomes. In the current issue of <i>Liver International</i>, Piñero et al. present a prospective, multicenter observational study on the effect of recompensated cirrhosis on survival in Latin American patients with uHCC receiving systemic therapy. This study highlights hepatic recompensation as a possible inflection point in patient outcomes. Their study included 240 patients with cirrhosis from 2018 to 2024 (compensated cirrhosis, 53.7%; decompensated cirrhosis, 28.8%; and recompensated cirrhosis, 17.5%) [<span>6</span>]. Cirrhosis classification was based on the Baveno VII definition [<span>7</span>]. The key findings are compelling, as patients with recompensated cirrhosis (those previously decompensated but with recovered hepatic function) had similar survival rates to those with compensated cirrhosis (hazard ratio [HR]: 1.28, 95% confidence interval [CI]: 0.76–2.10), those with decompensated cirrhosis had a significantly worse prognosis (HR: 1.91, 95% CI: 1.04–3.51).

Ten ML models were developed based on seven consensus-selected baseline features, with the survival gradient boosting machine (GBM) demonstrating superior performance compared to the traditional Cox proportional hazards regression model and other relevant models or scores. The GBM model achieved a Harrell's concordance index of 0.853 (95% CI: 0.791–0.914) in the external validation set. To facilitate clinical application, the GBM model was interpreted globally and locally and deployed as a web-based tool using the Streamlit-Python framework.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The GBM model demonstrated excellent performance in predicting HEV-ALF risk in hospitalised patients with AHE, offering a promising tool for clinical decision-making.</p>\u0000 </section>\u0000 </div>","PeriodicalId":18101,"journal":{"name":"Liver International","volume":"45 6","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
