Occurrence and prognosis of extranodal lymphomas

TLDR

A population‑based cohort of 1,467 Caucasian patients with non‑disseminated extranodal lymphomas from 1950‑1964 was analyzed for survival rates by site of origin, major histologic type, sex, age, extent of disease, and initial treatment. About one quarter of reported extranodal lymphomas arose outside lymph nodes, and patients with stomach, lung, or tonsil involvement fared better than the average cancer at those sites.

Abstract

A series of 1,467 Caucasian patients with non-disseminated lymphomas of extranodal origin was taken from data collected by the End Results Group of cancer registries in the years 1950-1964. Excluding Hodgkin's disease, about one fourth of the lymphomas reported arose in sites other than lymph nodes. Survival rates and distributions are listed for site of origin, major histologic types, sex, age, and extent of disease. For the more frequently reported sites, survival rates are given according to the type of initial treatment used. The prognosis of patients with extranodal lymphomas is compared with that for “all cancers” of the same site, and the lymphoma patients appear to fare appreciably better when the site of origin is stomach, lung, or tonsil.
