As shown in Table 2, the density of CD8+ T cells and CD33+/p-STAT1+ cells was significantly correlated with patient vital status (p = 0.023, p < 0.001) and relapse occurrence (p = 0.005, p = 0.001); in addition, the high-density group of CD8+ T cells had a smaller tumor size (p = 0.005). The gene discussed is CD8A; the disease is neoplasm.
