The primary end point was 1-year disease-free survival (DFS). Secondary outcomes included inflammatory cytokine levels, leukocyte counts, and scores from the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 item (GAD-7), and the 5-level European Quality of Life Five-dimension (EQ-5D-5L) assessment.</p><p><strong>Results: </strong>One-year DFS was higher among the screening cohort than the controls (91.4% vs 81.2%; <i>P</i> <⁠0.001). The levels of anxiety and depression decreased over time in the screening cohort, with lower mean (SD) PHQ-9 scores of 8.19 (1.32) 1 month postoperatively and 6.9 (1.33) at 3-month follow-up (<i>P</i> <⁠0.001), and lower mean (SD) GAD-7 scores of 7.73 (3.94) 1 month after surgery and 5.01 (3.31) 3 months postoperatively (<i>P</i> <⁠0.001), as compared with the controls. At 3 months postsurgery, the screening cohort showed better outcomes than the controls in terms of the levels of interleukin-6 (<i>P</i> = 0.003) and tumor necrosis factor α (<i>P</i> <⁠0.001), as well as the CD3+ cell count (<i>P</i> = 0.02), CD4+/CD8+ ratio (<i>P</i> = 0.02), and natural killer cell count (<i>P</i> = 0.006). The patients undergoing screening exhibited greater improvements in the EQ-5D-5L scores over time than the controls (<i>P</i> <⁠0.001). Minor adverse events were observed in 8.2% of the screening cohort.</p><p><strong>Conclusions: </strong>Time-dynamic screening for GI cancers effectively reduces anxiety and depression after surgery, improves immune function, and enhances quality of life, thus contributing to a better prognosis at 1 year follow-up.</p>","PeriodicalId":49361,"journal":{"name":"Videosurgery and Other Miniinvasive Techniques","volume":"20 4","pages":"424-431"},"PeriodicalIF":1.9,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12933845/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147311851","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}
