Study Description

Brief Summary

To assess the efficacy and safety of lenalidomide combined with rituximab, vincristine, doxorubicin, cyclophosphamide, and prednisone (r2-chop) in the initial treatment of DEL-DLBCL. The primary endpoint is the complete response rate, and the second endpoints are survival time (OS and PFS) and overall response rate.

In those patients with at least one evaluable or measurable lesion meeting Lugano 2014 criteria, the evaluable lesion was: 18F fluorodeoxyglucose / positron emission tomography (18FDG / PET) examination showed that the uptake of lymph nodes or extranodal areas was increased (higher than that of liver) and pet and / or computed The features of tomography (CT) were in accordance with lymphoma. The measurable lesions were nodal lesions with a length of > 15 mm or extranodal lesions with a length of > 10 mm, accompanied by an increase in 18FDG uptake. There was no measurable lesion and the uptake of 18FDG was increased.
