Application of PD-1 Inhibitors, Tenofovir, Chidamide, and Lenalidomide in Relapsed/Refractory EBV-associated Lymphoproliferative Disorders.

This study investigates a novel multi-targeted regimen combining a PD-1 inhibitor, tenofovir, chidamide, and lenalidomide for relapsed/refractory EBV-associated lymphoproliferative disorders (LPDs). Unlike conventional therapies focused on antivirals or chemotherapy alone, this approach integrates antiviral suppression, epigenetic reactivation, immune modulation, and checkpoint blockade to achieve synergistic antitumor and antiviral effects. Preliminary data show effective EBV inhibition and tumor regression. This strategy offers a promising and distinct therapeutic option for EBV-driven lymphoid malignancies resistant to standard treatment.
