The treatment records of 107 patients with stage I diffuse non-Hodgkin's lymphoma of the Waldeyer's ring, who were irradiated at 7 institutions from 1972 through 1985, were analyzed. The local control rate, the 5 year actuarial survival rate and the 5 year relapse-free survival rate were 96.4%, 76.2% and 76.6%, respectively. Any high risk group could not be found in the pathological subtype, the initial site of the tumor and the tumor size. There were 17 relapse cases within the first 2 years after radiotherapy. Most relapse occurred in the distant site from the irradiated field. With these results, the treatment policy of Waldeyer's ring lymphoma of stage I was discussed.
