Supplementary Figure 2 shows a heatmap of the total tumor cell count, total number of tumor and immune cells expressing PD-L1, and PD-L1+ tumor and macrophage count within the tumor bed. As shown in Table 4, there was no change in the median PD-L1+ tumor cell numbers post-treatment. However, there was a slight reduction in PD-L1+ macrophage cell counts (p=0.041), while the median percent change showed an increase (158%, p=0.007). Here, CD274 is linked to neoplasm.
