There was no significant difference in overall survival (OS) between patients with DLBCL classified into two groups (high and low) according to PD-1 expression (Figure 3A), whereas OS was lower in patients with DLBCL in the high LAG-3 expression group than in those with low LAG-3 expression (Figure 3B). This evidence concerns the gene PDCD1 and diffuse large B-cell lymphoma.
