Zanubrutinib, lenalidomide, and rituximab (ZR2 regimen) for HIV-associated diffuse large B-cell lymphoma: a real-world analysis from China

Seven patients with HIV-associated diffuse large B-cell lymphoma (HIV-DLBCL) who did not derive benefit from traditional first-line or second-line chemotherapy were all eventually treated with zanubrutinib, rituximab, and lenalidomide (the ZR2 regimen). Three patients had a complete response, three had a partial response, and one showed stable disease. The complete response rate was 42.9%, the overall response rate was 85.7%. Three patients developed either neutropenia or thrombocytopenia, and one died of lung infection 3 months after diagnosis.
