Epidemiology of Hodgkin's Disease

TLDR

Hodgkin’s disease shows age‑dependent epidemiology with distinct patterns in children, young adults, and older adults, and a bimodal incidence curve suggests heterogeneity of the disease. The study proposes two hypotheses linking epidemiologic patterns to distinct pathological and prognostic subtypes of Hodgkin’s disease. The findings identify at least three etiologically distinct subgroups, with young‑adult disease characterized as chronic granulomatous inflammation and disease in those over 50 as a neoplasm.

Abstract

Summary The epidemiologic features of Hodgkin9s disease vary with age at clinical onset. Three age periods can be distinguished: 0–14, 15–34, and 50 and over. The epidemiologic features of the disease in these 3 periods are summarized in Table 9. Bimodality of the age incidence curve augments the idea that the entity as now described is heterogeneous. Two hypotheses are proposed on the basis of the epidemiologic evidence and a brief consideration of pathology and prognosis. First, patients now categorized as having Hodgkin9s disease include at least 3 subgroups, the etiology of which may be quite distinct. Second, Hodgkin9s disease in young adults is a chronic granulomatous inflammation, whereas that occurring in persons over 50 is a neoplasm.
