CD8A and neoplasm: Intriguingly, we also found that the pre-treatment score from RM-periFC positively correlated with the stromal density of CD8+ T cells at the tumor periphery (as mentioned before; see Figure 4H), which was higher in the non-ypCR group than in the ypCR group (P = 0.006, Student’s t-test; Figure 6C), without significantly differing according to the molecular subtype (one-way ANOVA, P = 0.68; Figure 6D).
