A Case of Plasmablastic Lymphoma Achieving Complete Response and Durable Remission after Lenalidomide-Based Therapy

Abstract

Background: Plasmablastic lymphoma (PBL) is an uncommon variant of diffuse large B-cell lymphoma that is characterized by its plasmacytoid features, aggressive tendencies, and frequent association with human immunodeficiency virus (HIV) infection or other immunocompromised states. Multi-agent, intensive chemotherapy regimens are recommended as first-line treatment by the National Comprehensive Cancer Network. However, the toxicity of these regimens is high and prognosis remains poor. Case Report: We report a patient with HIV-negative PBL who achieved complete response and durable remission using a lenalidomide-based chemotherapy regimen as first-line therapy. Conclusion: Cyclophosphamide, lenalidomide, dexamethasone (CRD) may provide an alternative initial therapeutic option for patients with PBL who cannot tolerate the intensive chemotherapy regimens currently recommended.
