CD8A and nasopharyngeal carcinoma: The results revealed different immune infiltration in NPC tissues (Fig. 6c) and confirmed that B cells and intratumor CD8+ T cells were significantly more abundant in low-risk patients (Intratumoral CD20+ B cells, P = 0.011; stromal CD20+ B cells, P = 0.031; intratumoral CD8+ T cells, P = 0.045; Fig. 6d).
