According to the xCELL database, patients in the high-risk score group had higher abundance levels of class-switched memory B cell, common lymphoid progenitor, common myeloid progenitor, mast cell, NK T cell, Th1 CD4 T cell, and Th2 CD4 T cell, and lower abundance levels of naïve CD8 T cell, CD8 T cell, central memory CD8 T cell, endothelial cell, cancer-associated fibroblast, granulocyte monocyte progenitor, hematopoietic stem cell, macrophage, macrophage M2, and plasmacytoid dendritic cell when compared with patients in the low-risk score group. Here, CD8A is linked to cancer.
