In relation to tumor-infiltrating lymphocytes, it was found that immune-active cells including B cells (Spearman’s ρ=-0.250, p <0.001), CD8+ T cells (Spearman’s ρ=-0.299, p <0.001), and NK cells (Spearman’s ρ=-0.258, p <0.001) correlated negatively with ERO1L expression. This evidence concerns the gene CD8A and neoplasm.
