Second primary cancers following treatment of Hodgkin's disease.

A cohort study designed to evaluate the carcinogenicity of treatment for Hodgkin's disease (HD) was conducted. This report describes 2,591 patients with HD diagnosed in 1940-75 and presents an analysis of follow-up findings through 1978. Seventy-four second primary cancers (excluding basal cell and squamous cell cancers of the skin and in situ carcinomas of the cervix uteri) were observed 1 year or more after diagnosis of HD, including 21 leukemias.
