Within a median follow-up period of 62.5 months, the additional surgery and follow-up groups showed 5-year overall survival rates of 79.4% and 76.8% (P = 0.93) and disease-specific survival rates of 92.9% and 92.7% (P = 0.98). A total of 19 low-, 8 intermediate-, and 4 high-risk patients in the follow-up group achieved 5-year disease-specific survival rates of 100%, 100%, and 33.3%. Significant differences were observed in the disease-specific survival between the low- and high-risk patients (P < 0.001) and between the intermediate- and high-risk patients (P = 0.02).</p><p><strong>Conclusion: </strong>Risk stratification using the eCura system allows for individualized treatment decisions, with follow-up being a viable option for low- and intermediate-risk patients and additional surgery recommended for high-risk patients after non-curative endoscopic submucosal dissection for remnant gastric cancer.</p>","PeriodicalId":15895,"journal":{"name":"Journal of Gastrointestinal Cancer","volume":"56 1","pages":"80"},"PeriodicalIF":1.6,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
