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 occured commonly in patients with Waldeyer's ring lymphoma and was found in five cases. Cancer 59:940-944, 1987.
