Figure 1. PD-L1 expression (IHC) staining of whole tissues slides of FFPE EBV+ GC and MSI GCs.

Figure 1

(A) EBV+ GC with 9p24.1 amplification (amp) has abundant PD-L1 expression of tumor cells. (B) EBV+ GC and MSI GC (C) with PD-L1+ immune cells with a tumor infiltrating infiltration pattern (TI). (D) MSI GCs with PD-L1+ immune cells exclusively at the invasive margin (IM) (D). Magnification 20×, insert indicates area of higher magnification. Associations between EBV status and PD-L1 expression in TCGA study (E) and validation series (F).
