A cohort study of cancer mortality in virologists.
Department of Epidemiology, Johns Hopkins University, Baltimore, Maryland, 1979 Jan; :1-23
Cancer mortality among virologists (SIC-8049) was studied. Virologists were identified from professional society membership roles. In an initial case control study, deaths from cancer in each society were matched with deaths from other causes, using age of entry, birth date, and age at death as the matching criteria. Membership information was updated for a cohort study of members of three societies suspected of having virus exposure in a proportion of their members. The three groups consisted of physiologists, pathologists, and immunologists. Incidence and type of cancer were determined, and results were compared with those for all United States White males and for physicians not exposed to viruses. In the case control study, virologists did not have a higher overall cancer rate than the unexposed groups, but there was some increase when the virus exposure was subclassified into tumor viruses or other. Mortality from liver and pancreas cancer was higher among virologists in the cohort study than among the comparison groups. The risk of these cancers for virologists was 2.5 to 7.7 times that for psychiatrists. One or more of the groups of virologists also had excess mortality rates for kidney, brain, esophageal, and small intestinal cancers and other lymphomas. The authors conclude that more complete studies are needed to determine whether the excess incidence of certain types of cancer among virologists is associated with exposure to viruses.
