Totally, the ORR at EOT was 94.7%, and all achieved CMR. The ORR of patients with PD-L1 positivity(n=10) was numerically higher than that of patients with negative PD-L1 expression (n=5) (100% vs 80%)...PD-1 blockade combined with R-CHOP as induction therapy in patients with newly diagnosed EBV+ DLBCL has demonstrated satisfactory response and limited irAEs.
