R2 and Combination Chemotherapy Versus R and Combination Chemotherapy in Newly Diagnosed Highly Aggressive B-NHL

Lymphoma has become one of the top ten malignant tumors, of which non-Hodgkin's B-cell lymphoma accounts for the majority. As the classic first-line treatment, the emergence of the R-CHOP program has resulted in clinical cures for more than 1/2 of patients with B-cell lymphoma. But for patients with highly aggressively B cell lymphoma, most of them still suffer from disease recurrences due to R-CHOP treatment alone. In recent years, with the emergence of various new drugs, many researchers have tried to add new drugs to the classic R-CHOP program as a first-line treatment for non-Hodgkin B-cell lymphoma. As a new type of immunomodulator, lenalidomide was first approved for the treatment of multiple myeloma. In recent years, its role in refractory and relapsed B-cell lymphoma has gradually been recognized. In 2015, Nowakowski et al. published a clinical study of 64 patients with diffuse large B-cell lymphoma who used R2-CHOP in first-line therapy. It was found that R2-CHOP does not improve R-CHOP in patients with GCB. The effective rate of treatment and the 2-year survival rate of patients, but for patients with non-GCB type DLBCL with poor prognosis, the addition of lenalidomide can greatly improve the remission rate of the disease and improve the poor prognosis of patients. So, the investigators initiate this study to evaluate the efficacy of R2-CHOP/R2-EPOCH etc in newly diagnosed highly invasively non-Hodgkin B-cell lymphoma.
