This study aimed to systematically evaluate the association between pretreatment GRIm score and survival outcomes in patients with gastrointestinal (GI) cancers.  \nMethods A systematic literature search was conducted using electronic databases (Web of Science, PubMed, Cochrane Library and Embase) from inception to January 15, 2026. The primary endpoints included long-term survival outcomes such as overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS), progressionfree survival (PFS), and cancer-specific survival (CSS) . Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using a random-effects model. The meta-analysis was prospectively registered with PROSPERO (CRD420261291292) .  \nResults This meta-analysis included 16 studies comprising 4,904 patients with GI cancers. The pooled outcomes demonstrated that patients with a high GRIm score had significantly worse OS (15 studies; HR = 2 . 01; 95% CI: 1.69– 2.40; P \u003C 0. 01; I² = 63%), PFS (8 studies; HR = 1 . 57; 95% CI: 1 .29–1. 91; P \u003C 0. 01; I² = 48%), DFS (2 studies; HR = 2 . 15; 95% CI: 1 .35–3.42; P \u003C 0. 01; I² = 55%) and CSS (2 studies; HR = 1 . 68; 95% CI: 1 .17–2.41; P \u003C 0. 01; I² = 4%) compared to those with a low score. However, a single study assessing RFS reported that the GRIm score lacked independent prognostic significance for this endpoint (HR = 1 . 69; 95% CI: 0 .77–3. 73; P = 0 . 19) .  \nConclusions Our findings suggest that the pretreatment GRIm score may serve as a prognostic biomarker in patients with GI cancers. However, further high-quality studies are required to robustly validate its prognostic utility.  \nKeywords Gastrointestinal Cancer, Gustave Roussy immune score, Overall survival, Disease-free survival, Progressionfree survival, Cancer-specific survival  \n†Xiaolian Deng and Tingting Yan contributed equally to this work.  \n*Correspondence:  \nJinlai Wei [weilai03109@163.com](weilai03109@163.com)[ ](weilai03109@163.com)Chunxue Li[lichunxue@tmmu.edu.cn](lichunxue@tmmu.edu.cn)  \n1Department of General Surgery, Daping Hospital, Army Medical University (Third Military Medical University), Chongqing 400042, China 2Department of Gastrointestinal Cancer Center, Chongqing University Cancer Hospital, Chongqing 400030, China  \n3Department of Gastrointestinal Surgery, the First Affiliated Hospital of Chongqing Medical University, Chongqing 400016, China  \n© The Author(s) 2026.
