SOX2 and neoplasm: Our data showed that a low density of tumoral CD20+ TILs were associated with a poorer DSS in patients with positive tumoral PD-L1 expression (p = 0.008), negative SOX2 (p = 0.01) or negative NANOG expression (p = 0.03), in cases with high infiltration of CD8+ TILs in the tumor nests (p = 0.03), and in cases with low density of stromal CD4+ and tumoral CD68+ cells (p = 0.03) (Table S4).
