title: Clinical analysis of extranodal non-Hodgkin's lymphoma in the sinonasal tract.
abstract: We investigated the clinical analysis of non-Hodgkin's lymphoma (NHL) of the sinonasal tract, including the survival rate and treatment outcome. Fifty patients who had previously received a diagnosis of extranodal NHL of the sinonasal cavity from May 1992 to April 2001 were included. We reviewed the patients' clinical characteristics and the survival rates, retrospectively. Of 50 patients, 49 were classified as having extranodal NK/T cell lymphoma and only one patient as having diffuse large B cell (DLBC) lymphoma according to the new WHO classification. Even though higher mortality rates were observed in patients receiving chemotherapy alone than in those receiving chemotherapy and radiation therapy in the advanced stage, the combination treatment of chemotherapy and radiation therapy failed to demonstrate a significantly higher survival rate.
