Stages I and II non-Hodgkin's lymphomas of Waldeyer's ring and the neck.

In a previous communication we reported our results for patients with localized extranodal presentations of non-Hodgkin's lymphomas of the head and neck who were admitted between 1961-1969. This review describes our larger experience from 1947-1982 in treating 137 Stages I and II Waldeyer's ring patients whose slides were available for reclassification according to the modified Rappaport System. All of these patients were treated definitively as follows: radiotherapy only, 113 patients; radiotherapy and combination chemotherapy, 17 patients; chemotherapy only, seven patients. The overall 5-year survival was 50%. Significant differences were determined for specific subgroups. For patients staged after lymphangiography, the 5-year survival was 67% as compared with 32% for non-lymphangiogram staged patients (p = 0.002). Stage (Ann Arbor) also influenced results. The 5-year survival figure for Stage I was 70% as compared with 42% for Stage II (p = 0.002). The combination of extent of disease in Waldeyer's ring and the status of the neck had a major impact on survival. When the disease was staged according to the TNMAJCC System, the 5-year survivals were: 75% for T1-T2-TX N0; 53% for T1-T2-TX N+; 54% for T3-T4 N0; and 36% for T3-T4 N+. Also, results for tonsil (52%) and base of tongue (66%) disease were better than for disease involving the nasopharynx (39%) or multiple sites (25%). Treatment also influenced survivals and disease-free survivals. The best results were obtained in patients who were treated with radiotherapy and combination chemotherapy. The 5-year survival and disease-free survival figures were 78% and 69%, respectively.
