The results revealed that the pathways enriched in GI cancer tissues with high SLAMF8 expression were associated with an activated antitumor immune response, including T‐cell activation, antigen presentation and positive regulation of IFN‐γ production (Supplementary figure 3a), and most of them intersected with the pathways enriched in EBV+ GC tissues (Supplementary table 4). Here, IFNG is linked to gastric cancer.
