From 1966 through 1988, 124 patients with non-Hodgkin's lymphoma of the Waldeyer's ring were treated. Seventy patients were male, and 54 were female. Age ranged from 5 to 81 years with a median value of 53 years. Pathological slides were reviewed and reclassified according to the Working Formulation. Diffuse large cell type was most common (53%). Since 1981, CHOP has been incorporated into the treatment including stage I and II patients. During these 22 years, new imaging modalities have developed, and an upstage rate by using those modalities has increased from 5% to 9%. In order to make the comparison meaningful, we used clinical stage determined at the day of the first visit. Fifty-one patients were clinical stage I, 64 were stage II, seven were stage III, and two were stage IV. B symptom was seen in 8 patients. Relapse developed in 45 patients (41%) out of 111 who achieved complete remission, and distant relapse was most frequent (89%). Salvage therapy was successful in only three patients of the 45 relapsed patients. Overall 5-year freedom from relapse (FFR) were 38% for the patients treated until 1980, and 69% for the patients treated thereafter (p less than 0.01). Addition of CHOP to radiotherapy has increased 5-year FFR of the stage II patients from 31% to 81% (p less than 0.01). In stage I, 5-year FFR was 71% in the patients treated with CHOP and radiotherapy, and it was 27% treated without CHOP. But the difference has no statistical significance, and we can not rule out the presence of selection bias.(ABSTRACT TRUNCATED AT 250 WORDS)
