Kaplan-Meier curves of EBV⁺ LBLCs in young patients. (A) Overall survival of morphological subgroups of EBV⁺ LBCLs in young patients (≤45 years); overall survival THRLBCL-like vs GZL at 3 years is 95.8% and 75%, respectively (P = .17). (B) Overall survival of EBV⁺ LBCL in young patients, all groups, regardless of morphological pattern and EBV⁺ DLBCL in elderly patients (>45 years of age) including all causes of death, is 89.0% and 24.4% at 5 years, respectively (P < .0001).
