Double Expressor Lymphoma
Conditions
Brief summary
In this phase II study, the investigators are aiming to explore lenalidomide combined with R-CHOP (R2-CHOP) in newly diagnosed double-expressor Diffuse Large B-Cell Lymphoma patients (DLBCL)
Detailed description
Double expressor lymphoma is a subtype of diffuse large B-cell lymphoma defined as having increased expression of MYC and BCL-2 by immunohistochemistry. Patients with double-expressor lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of progression and recurrence. The investigators conducted this study to evaluate the efficacy of lenalidomide combined with R-CHOP (R2-CHOP) in newly diagnosed double-expressor, untreated Diffuse Large B-Cell Lymphoma patients (DLBCL). Lenalidomide is the second-generation immunomodulatory drug, and its anti-tumor mechanism may involve immunomodulatory, antiinflammatory, and antiangiogenic effects and suppression of tumor necrosis factor-alpha (TNF-α) from peripheral blood mononuclear cells. In this phase II study, the investigators are aiming to explore lenalidomide combined with R-CHOP (R2-CHOP) in newly diagnosed double-expressor Diffuse Large B-Cell Lymphoma patients (DLBCL), in order to find a potential promising way to treat this kind of disease.
