Reliable proportions of cancer‐associated fibroblasts (CAFs), macrophages, B cells, CD4/CD8 T cells, endothelial cells, natural killer cells (NK cells), neutrophils, and tumor cells were computed for n = 375, n = 62, and n = 85 patients in TCGA, MDACC, and FHCRC, respectively. This evidence concerns the gene CD8A and neoplasm.
