Pancreatic cystic lesions (PCLs) are frequently, incidentally identified in more than a quarter of patients above the age of 70 and while the vast majority of these lesions are indolent, some may develop into malignancy. Similarly, while the risk of hepatocellular carcinoma (HCC) is well established in patients with cirrhosis, the proportion of the elderly population with cirrhosis is rapidly expanding, especially in the setting of metabolic dysfunction–associated steatohepatitis. While multiple guidelines define these high-risk populations and provide recommendations on how and when to implement surveillance, these same guidelines rarely specify when to stop surveillance particularly in cases of advanced age or infirmity where the patient’s attributable mortality to the surveyed condition or fitness to receive invasive treatments is unclear. In this Clinical Practice Update (CPU), we review evidence-based, patient-centered, practical approaches to assess appropriateness for PCL and HCC surveillance in older individuals, weighing the balance of potential benefit vs harms and the impact of comorbidities and life expectancy on shared decision-making.","PeriodicalId":10347,"journal":{"name":"Clinical Gastroenterology and Hepatology","volume":"53 1","pages":""},"PeriodicalIF":12.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is traditionally divided into lymphocytic colitis (LC), defined by an increased intraepithelial lymphocyte count, and collagenous colitis (CC), characterised by a thickened subepithelial collagen band. However, these categories do not fully capture the biological heterogeneity of the disease. Conventional histology remains crucial for diagnosis yet provides only a static morphological assessment of a biologically dynamic disease and offers limited prognostic or treatment-predictive information. Nevertheless, several clinically recognisable mechanisms and phenotypes already provide opportunities for patient stratification and, in selected cases, mechanism-informed management, including medication-associated MC, bile acid malabsorption, immune checkpoint inhibitor-associated MC, coexistent coeliac disease, and smoking-related risk. Beyond these clinically identifiable phenotypes, emerging OMICS evidence reveals heterogeneity across immune, epithelial barrier, stromal, microbial-metabolic, and genetic domains. Importantly, these molecular domains currently represent candidate mechanistic phenotypes rather than validated endotypes, as patient-level reproducibility and associations with disease trajectory or differential treatment response remain insufficiently established. This narrative review critically appraises current histological and molecular biomarkers in MC and their potential to improve disease stratification. Moreover, artificial intelligence-driven multimodal approaches may ultimately complement morphological assessment, improve patient characterisation and support the prediction of treatment response. We further define the validation steps required to translate emerging biological signatures into clinically meaningful endotypes and precision medicine.</p>","PeriodicalId":10347,"journal":{"name":"Clinical Gastroenterology and Hepatology","volume":" ","pages":""},"PeriodicalIF":16.2,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149073674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
