Abstract

Abstract We evaluated the clinical outcomes and relapse patterns of 80 patients with primary sinonasal tract diffuse large B-cell lymphoma (SN-DLBCL) treated with rituximab-cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) chemotherapy at 22 institutions. A total of 59 (73.8%) patients received R-CHOP chemotherapy alone, whereas 21 (26.3%) were treated with R-CHOP followed by involved field radiotherapy (IFRT). In 73 patients with Ann Arbor stage I-II disease, no significant difference was found in the response rate or overall survival (OS) between R-CHOP alone (n = 52) and R-CHOP followed by IFRT (n = 21). Among 11 relapsed patients in this study, the most common pattern of relapse was local (n = 8, 11.8%), whereas central nervous system (CNS) relapse was observed in only one (1.9%) patient. These results suggest that patients with primary SN-DLBCL treated with R-CHOP have a relatively low CNS relapse rate and better OS compared to previous studies before the introduction of R.
