title: A comparison of Hodgkin's disease in Alameda County, California, and Connecticut: histologic subtype and age distribution.
abstract: A comparison of the histologic patterns of Hodgkin's disease in Alameda County, California and Connecticut was made in relation to age. All Hodgkin's disease cases from the Alameda County Cancer Registry diagnosed between 1960 and 1969 for which adequate material was available for evaluation were reviewed and histologically subtyped according to the Rye classification (159 cases). The age-specific relative frequencies and incidence rates for the histologic subtypes of Hodgkin's disease in Alameda County were estimated and compared to those estimated for Hodgkin's disease in Connecticut. The morphologic ex pression of Hodgkin's disease in both areas was similar and characteristic of economically developed regions with high living standards. The comparison supports the hypothesis that the host immune capacity, influenced by socioeconomic factors, has a strong and measurable effect on the pathogenesis of Hodgkin's disease.
