Twenty-five patients with sinonasal lymphoma were treated mainly with irradiation. All were non-Hodgkin lymphomas of diffuse type. Twenty patients had stage IA, 2 had stage IB, 1 stage IIA, I stage IIIA, and I stage IVA disease. Relapse developed in 16 (64% of the 25 patients, with a failure rate of 64 per cent in the stage I patients (14/22). Most patients with failures had distant spread of the disease with or without local recurrence. Only one patient had local recurrence alone at the first relapse. Histologic classification according to the new working formulation seemed to be a reliable prognostic indicator for relapse: failure rates for low, intermediate, and high grade lymphomas were 0 per cent (0/2), 46 per cent (6/13), and 100 per cent (10/10), respectively. Computed tomography was valuable for planning of radiation therapy and for follow-up.
