Furthermore, T stage (P = 0.019, P = 0.012), tumour-associated N2 neutrophils (P < 0.001, P < 0.001), tumour-associated N2+ neutrophils (P = 0.009, P < 0.001), CD8+ T cells (P = 0.025, P = 0.007), and Treg cells (P < 0.001, P < 0.001) were significantly associated with both PFS and OS. Here, CD8A is linked to neoplasm.
