Plasmablastic lymphoma: 2024 update on diagnosis, risk stratification, and management
Disease Overview
Plasmablastic lymphoma (PBL) is a rare CD20-negative aggressive lymphoma with a poor prognosis under standard treatment options. Though PBL is associated with human immunodeficiency virus infection and other immunosuppressed states, it can also affect immunocompetent individuals.
Diagnosis
The diagnosis requires a high clinical suspicion and pathological confirmation. EBER expression and MYC gene rearrangements are frequently detected. The differential diagnosis includes EBV+ diffuse large B-cell lymphoma, extracavitary primary effusion lymphoma, ALK+ DLBCL, and HHV8+ large B-cell lymphoma, among others.
Risk Stratification
Age ≥60 years, advanced clinical stage, and high intermediate and high International Prognostic Index scores are associated with worse survival.
Management
Combination chemotherapy regimens, such as EPOCH, are recommended. The addition of bortezomib, lenalidomide, or daratumumab might improve outcomes. Including PBL patients and their participation in prospective clinical trials is warranted.
期刊介绍：
The American Journal of Hematology offers extensive coverage of experimental and clinical aspects of blood diseases in humans and animal models. The journal publishes original contributions in both non-malignant and malignant hematological diseases, encompassing clinical and basic studies in areas such as hemostasis, thrombosis, immunology, blood banking, and stem cell biology. Clinical translational reports highlighting innovative therapeutic approaches for the diagnosis and treatment of hematological diseases are actively encouraged.The American Journal of Hematology features regular original laboratory and clinical research articles, brief research reports, critical reviews, images in hematology, as well as letters and correspondence.
