To follow up on these observations, we correlated the pathological scoring of CD8+ T cells and stroma content assessment with calculated tumor purity and stromal immune cell admixture and found positive correlations (Figure S11; tumor purity: R = 0.51, p < 0.001; stroma purity vs. estimate R = 0.44, p < 0.001; stroma purity vs. xCell R = 0.33, p = 0.004). This evidence concerns the gene CD8A and neoplasm.
