The role of CEACAM6 in pan‐gastrointestinal cancers remains largely uncharacterized. This study employed multi‐omics bioinformatics to investigate the expression distribution, prognostic value, and immune function of CEACAM6 in these malignancies.  \nMethods: Utilizing multi‐omics data from The Cancer Genome Atlas (TCGA), cBioPortal, GDSC2, TIMER2.0, and TISCH databases, we assessed the CEACAM6 expression and prognostic value across pan‐gastrointestinal cancers. Additionally, the potential role of CEACAM6 in the tumor immune microenvironment was explored using multi‐omics data, including spatial transcriptomics data.  \nResults: Based on TCGA data, CEACAM6 was found to be overexpressed in pan‐gastrointestinal cancers. The CEACAM6 somatic copy number alterations, DNA methylation and mutation sites were identified as potential contributors to abnormal CEACAM6 expression. The CEACAM6 expression was significantly negatively associated with the abundance of CD4 + Th1 cells across pan‐gastrointestinal cancers. Furthermore, spatial transcriptomics data revealed that CEACAM6 expression was significant positively associated with malignant cells, while there was a negative correlation was observed with between CEACAM6 expression and plasma cells.  \nConclusion: CEACAM6 exhibits high diagnostic accuracy and tumor‐specific overexpression in pan‐gastrointestinal cancers. CEACAM6 could promote angiogenesis/metastasis and suppress anti‐tumor immunity. Spatially localized in tumors with immune cell exclusion, CEACAM6 correlates with poor survival and immune‐excluded subtypes, positioning it as a therapeutic target in precision immunotherapy for pan‐gastrointestinal cancers.  \n\n| Liying Jin and Changjuan Tao contributed equally to this work. |\n| --- |\n| This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.\u003Cbr>© 2026 The Author(s) .
