Nasal diffuse large B-cell lymphoma (DLBCL) is rare. The objective of this study was to evaluate the clinical features and treatment outcomes of patients with nasal DLBCL.


Twenty-five patients were included in the study. All patients received combination chemotherapy with or without radiotherapy.


Patients with nasal DLBCL usually were older and were predominantly men with early stage disease, low frequency of B symptoms and elevated lactate dehydrogenase (LDH), good performance status, and a low-risk international prognostic index (IPI) score. The overall response rate after initial treatment was 76%, the 3-year overall survival (OS) rate for the whole group was 44%, and the median OS was 35 months. Performance status and IPI were significant prognostic factors for OS. For patients with IPI scores of 0 or 1, the 3-year OS rate was 54%, and the median OS was 52 months compared with 17% and 11 months, respectively, for patients with IPI scores of 2 or 3 (P = .033). The prognosis for patients who achieved a complete response (CR) was significantly better than that for patients who did not achieve a CR. Extranodal spread was the primary pattern of failure.


The current results indicated that primary nasal DLBCL appears to have distinct clinical features; its poor outcome and propensity for extranodal failure illustrate the need for innovative therapies. Cancer 2011;. © 2011 American Cancer Society.
