Brief summary: The purpose of this study is to evaluate the efficacy of Thalidomide combined with R-CHOP(RT-CHOP) in newly diagnosed，untreated 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 and/or BCL-6 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 Thalidomide combined with R-CHOP(RT-CHOP) in newly diagnosed double-expressed, untreated Diffuse Large B-Cell Lymphoma patients (DLBCL). Thalidomide is a kind of glutamate derivatives, which can inhibit angiogenesis by blocking bFGF and VEGF, and it can also modulate the immune system by co-stimulating T cell proliferation. In addition, thalidomide can also inhibit the IKK activity and block the activation of NF-kB. In this open-label, randomized, phase III study, we are aiming to compare Thalidomide combined with R-CHOP(RT-CHOP) and R-CHOP in newly diagnosed double-expressor Diffuse Large B-Cell Lymphoma patients (DLBCL), in order to find a potential promising way to treat this subtype of lymphoma.
