Representative images showing the distance from a cancer cell to the nearest immune cell in the non-recur and recur groups are presented (P12, non-recur; P53, recur) in Figure 4D. We found that the distance between cancer cells and immune cells in the non-recur group was shorter than in the recur group, although the difference was not statistically significant (i.e., recur/non-recur in total CD8+ T cells: 1.40-fold) (Supplementary Table S6). The gene discussed is CD8A; the disease is cancer.
