CD8A and hepatocellular carcinoma: Using results of CIBERSORT164,165 deconvolution of the same TCGA samples, we found evidence of higher CD8 + T cell infiltration in EBV-positive versus EBV-negative GC (median = 0.19 and 0.09, p = 7.4e-09), and in HPV-positive versus HPV-negative HNSCC (median = 0.13 and 0.07, p = 4.3e-10), but not between virus-positive and virus-negative HCC (Fig. 5C).
