Treatment of non-Hodgkin's lymphoma: A look over the past decade

The past decade has seen enormous changes in our understanding of lymphomas with a better classification (World Heath Organization) and identification of better prognostic factors; however, important genetic prognostic factors have not been completely analyzed. The appearance of rituximab and other monoclonal antibodies has completely revolutionized the treatment of this disease. If monoclonal antibodies have activity when used alone, most patients experienced relapse after such a treatment, even after maintenance therapy. The combination of rituximab with chemotherapy has now been shown in several randomized studies to increase the response rate, decrease the relapse rate, and prolong progression-free survival and overall survival. Rituximab plus CHOP (cyclophosphamide/doxorubicin/prednisone/vincristine; R-CHOP) has become the standard for patients with diffuse large B-cell lymphoma. Rituximab chemotherapy, probably with the CHOP regimen, is slowly gaining importance as the standard for patients with follicular lymphoma. Although little is known for other indolent lymphomas and mantle cell lymphoma, progress has been made there, too. Several questions remain for future randomized studies to continue our search toward cure.
