A cluster of Hodgkin's disease in a small community: evidence for environmental factors

R S Schwartz et al. Am J Epidemiol. 1978 Jul.

Abstract

A cluster of Hodgkin's disease (HD) cases occurred in a small rural town of 1250 people. Ten cases of HD and three cases of non-Hodgkin's lymphoma were identified within or linked to this town since 1954. This town therefore had an average annual incidence and mortality for HD of 29.3 and 16.7 cases per 100,000 population, respectively. Most cases of HD demonstrated case-contact associations, and a distinct geographic distribution. The data suggested that there was an environmental agent responsible for the elevated rates of HD. One unique aspect of this cluster is that this town has only one industry, a large grain elevator. The cases closely surrounded this elevator. We postulate that residents of the town are subject to chronic immune stimulation from mitogenic substances in this environment. These agents may alter immunity in the residents of this community and predispose them to acquiring HD.
