Abstract Disease overview Epstein Barr virus‐positive (EBV+) diffuse large B‐cell lymphoma (DLBCL), not otherwise specified (NOS) is an aggressive B‐cell lymphoma associated with EBV infection included in the WHO classification of lymphoid neoplasms since 2016. Although historically associated to poor prognosis, outcomes seem to have improved in the era of chemoimmunotherapy. Diagnosis The diagnosis is established through meticulous pathological evaluation. Detection of EBV‐encoded RNA (EBER) is the standard diagnostic method. The ICC 2022 specifies EBV+ DLBCL, NOS as occurring when >80% of malignant cells express EBER, whereas the WHO‐HAEM5 emphasizes that the majority of tumor cells should be EBER positive without setting a defined threshold. The differential diagnosis includes plasmablastic lymphoma, DLBCL associated with chronic inflammation, primary effusion lymphoma, among others. Risk‐stratification The International Prognostic Index (IPI) and the Oyama score can be used for risk‐stratification. The Oyama score includes age >70 years and presence of B symptoms. The expression of CD30 and PD‐1/PD‐L1 are emerging as potential adverse but targetable biomarkers. Management Patients with EBV+ DLBCL, NOS, should be staged and managed following similar guidelines than patients with EBV‐negative DLBCL. EBV+ DLBCL, NOS, however, might have a worse prognosis than EBV‐negative DLBCL in the era of chemoimmunotherapy. Therefore, inclusion of patients in clinical trials when available is recommended. There is an opportunity to study and develop targeted therapy in the management of patients with EBV+ DLBCL, NOS.
