The trial result should thus exclude routine adoption of that pathway, but it should not be interpreted as proof that every form of peritoneal-directed treatment is futile. Its multicomponent intervention was undertaken after brief systemic treatment, without mandatory laparoscopic confirmation of peritoneal response before randomisation, and frequently disrupted further systemic therapy. Meanwhile, DRAGON-01 has shown that repeated normothermic intraperitoneal paclitaxel can improve survival when added to systemic treatment, and STOPGAP has demonstrated the feasibility of serial laparoscopic reassessment and response-directed surgery in a Western pathway. Future trials should therefore separate two questions: whether intraperitoneal therapy adds benefit to contemporary biomarker-directed systemic treatment, and whether operative consolidation benefits the exceptional responders thereby identified.

Only ALBI and OKUDA were significantly associated with overall survival (HR 3.10; p < 0.001 and HR 5.02; p = 0.018, respectively). ALBI and CLIP showed the highest predictive accuracy for 3-, 6-, and 12-month survival. In multivariablee analysis, ALBI and OKUDA remained independent predictors of 12-month survival (HR 3.70; p = 0.001 and HR 5.01; p = 0.025, respectively). The ALBI score worsened significantly within 12 weeks after TARE (p < 0.001).</p><p><strong>Conclusion: </strong>The ALBI score was the strongest predictor of survival following TARE. In contrast, tumor burden showed limited prognostic relevance, underscoring hepatic functional reserve as a key determinant of outcomes after locoregional liver cancer therapy.</p>","PeriodicalId":15895,"journal":{"name":"Journal of Gastrointestinal Cancer","volume":"57 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13473070/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148723193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
