Time Trends and Risk Factors for Mesothelioma.
Epidemiological studies on mesothelioma were presented. Data from incidence, mortality, and survival studies indicated that the incidence pattern increases over time, and the differential in incidence between men and women increases in the mid 1960s. A difference was also observed between white and black males for pleural mesothelioma. The greatest excesses appeared to be in geographical areas where there were either large shipyards or asbestos manufacturing facilities. The 50 percent survival time from diagnosis for males was just under a year and appears to be unrelated to age at the time of diagnosis. For women under the age of 50, the 50 percent survival time from diagnosis was close to 3 years. The nine industries which appear to have a high incidence rate for mesothelioma included furnace or boiler installation or repair, shipbuilding or other shipyard work, insulation, textiles production, plumbing or heating repair, elevator installation or repair, brake lining installation or repair, building demolition, and production of paper products. The author concludes that the study strongly supports an association between mesothelioma and occupations or avocations with potential for asbestos (1332214) exposure. The greatest risk appears to come 35 to 50 years after the first employment for certain industries. A discussion of various aspects of the study was included.
