As shown in Figure 3G, the high-risk group had a high levels of regulatory T cells, T follicular helper cells, type 1 T helper cells, mast cells, and plasmacytoid dendritic cell infiltration in the tumour rather than activated CD4 T cells, activated CD8 T cells, type 17 helper T cells, and CD56 light/dim natural killer cells. Here, NCAM1 is linked to neoplasm.
