Primary non-Hodgkin's lymphoma of bone: results in 15 patients treated by radiotherapy combined with systemic chemotherapy.

The authors report on the results obtained in 15 patients with primary non-Hodgkin's lymphoma (NHL) of bone treated by radiotherapy and polychemotherapy; 86% of the patients (13 of 15) were continuously disease-free at a median follow-up of 70 months (42-104). No local recurrence was observed. The necessity of clearly distinguishing primary non-Hodgkin's lymphoma of bone from Ewing's sarcoma is discussed.
