PFS and OS Kaplan-Meier curves. PFS (A) is 84% and OS (B) is 68% at the median follow-up of 5 years. PFS (C) and OS (D) for patients with GCB versus non-GCB DLBCL. PFS (E) and OS (F) for EBV-negative versus EBV-positive DLBCL, and PFS (G) and OS (H) for CD4 cell count greater than 100 cells/μL (100 cells/mm3) versus less than 100 cells/μL (100 cells/mm3) at diagnosis.
