Although radical gastrectomy remains the primary treatment for this disease, postoperative complications frequently arise, negatively impacting short-term recovery and significantly reducing patients' quality of life. In this context, accurately predicting the risk of postoperative recurrence and metastasis, coupled with targeted interventions, could substantially improve patient outcomes. The C-reactive protein-triglyceride-glucose index (CTI), a composite biomarker that integrates metabolic disturbances and systemic inflammation, has garnered increasing attention in oncology. The prognostic nutritional index (PNI), a composite measure based on serum albumin and peripheral blood lymphocyte count, is used to evaluate both the nutritional status and systemic immune function of patients.

Correlation analysis revealed significant associations between certain radiomics and Habitat features and pathological indicators such as MVI and Ki-67 expression in HCC.</p><p><strong>Conclusion: </strong>An interpretable fusion model integrating clinical, radiomic, and habitat features can assist clinicians in identifying early postoperative recurrence of HCC, offering significant potential for prognosis prediction and clinical management.</p>","PeriodicalId":23762,"journal":{"name":"World Journal of Gastrointestinal Oncology","volume":"17 12","pages":"114037"},"PeriodicalIF":2.5,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12754287/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145890067","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}
