Cancer incidence and mortality in the Du Pont Company: an update

In a previous publication, Pell et al described the cancer epidemiologic surveillance program that was begun in the Du Pont Company in 1956 and presented standardized cancer incidence and mortality data through 1974 for Du Pont employees compared with such data for the US general population. This report provides the analysis of an additional 10 years of cancer incidence and mortality data, and examines time trends for specific cancer sites. Conoco, Inc, acquired in 1981, is not included in the analysis.
