Survival was assessed using Kaplan-Meier and Cox models. A predefined molecular-risk classification stratified patients into low (RAS/RAF wild-type, <i>SMAD4</i>-intact), intermediate (isolated <i>KRAS</i> mutation), and high risk (<i>NRAS, BRAF</i>, or <i>SMAD4</i> alterations). Machine-learning models predicted 24-month mortality.</p><p><strong>Results: </strong>Among 503 patients, molecular-risk groups demonstrated distinct survival (5-year OS: 74.5%, 56.6%, and 49.8%; <i>p</i><0.001). Intermediate- and high-risk groups were independently associated with worse survival (HR=1.71 and 2.60, respectively). Integrated clinicogenomic models modestly improved predictive performance (AUROC 0.697), with <i>BRAF</i> mutation, tumor sidedness, and age as key contributors. Inclusion of metastasectomy status increased AUROC but reflected post-treatment bias.</p><p><strong>Conclusion: </strong>Molecular-risk stratification and integrated modeling identify clinically meaningful prognostic groups in CRLM. These findings support incorporation of genomic profiling into precision surgical and transplant evaluation, while emphasizing the need for prospective validation.</p>","PeriodicalId":9516,"journal":{"name":"Cancer Genomics & Proteomics","volume":"23 4","pages":"617-628"},"PeriodicalIF":2.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13321708/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148350910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
