CD8A and CD274 expression were poorly correlated (Pearson’s r = 0.42, p < 0.0001) (Fig. 2a), and we observed that CD8A and CD274 expression did not differ according to histological type (squamous-cell versus nonsquamous cell), tumor stage, age, or sex (Supplementary Figures 3A–D). The gene discussed is CD274; the disease is neoplasm.
