title: Stage I and II Waldeyer's ring and oral-sinonasal non-Hodgkin's lymphoma.
abstract: Sixty-six patients with Ann Arbor Stage I and II Waldeyer's ring and oral-sinonasal non-Hodgkin's lymphoma are presented. Ten-year survival was better for the 32 patients with Waldeyer's ring non-Hodgkin's lymphoma (Stage I, 83%; Stage II, 75%) than for the 34 with oral-sinonasal non-Hodgkin's lymphoma (Stage I, 47%; Stage II, 50%). Diffuse large cell lymphomas were common in patients with Waldeyer's ring involvement (59%). In those affected in the oral-sinonasal region, 38% had high-grade lymphoma. There was a high incidence of extranodal relapses outside of the gastrointestinal tract in patients with oral-sinonasal lymphoma (10 cases). Gastrointestinal tract relapse occurred commonly in patients with Waldeyer's ring lymphoma and was found in five cases.
