CD8A and nonpapillary renal cell carcinoma: The statistical data of CD45RO+CD8+ T lymphocytes and CD45RA+CD8+ T lymphocytes showed that level of CD45RA+CD8+ T lymphocytes in ccRCC patients (n = 274) was lower than healthy people (n = 350) (p = 0.0037) (Figure 3B) and proportion of CD45RO+CD8+ T cells in ccRCC patients (n = 274) was higher than healthy people (p = 0.0057) (Figure 3C).
