From the ssGSEA results, we found that the immune cells, including B cells, CD8+ T cells, mast cells, follicular Th cells, Th1 cells, and tumor-infiltrating lymphocytes (TILs), were obviously increased in the low-risk set, and some pathways related to immune function (i.e., immune checkpoint pathway, cytolytic activity, inflammation-promoting, T-cell co-inhibition/stimulation, and INF-II response) were significantly activated in the low-risk group compared with that in the high-risk group (p < 0.05; Figure 9A). Here, CD8A is linked to neoplasm.
