These figures were lower than those reported by Suzuki et al. [104], who reported 4/8 (50%) EBV+ extranodal DLBCL, NOS and 6/108 (6%) extranodal EBV-negative DLBCL cases positive for PD-L1 using the same PD-L1-specific antibody and cut-off value. This evidence concerns the gene CD274 and diffuse large B-cell lymphoma.
