Abstract
The prevalence of asbestos (1332214) associated rounded atelectasis (AARA) within a well defined cohort of asbestos insulation workers was described. Clinical parameters of cases of AARA were compared to those of cases of lung cancer and mesothelioma discovered during the same survey of workers. A cohort of asbestos insulation workers in the United States and Canada was established on 1 January of 1967. A total of 5377 members of the cohort who were alive in 1981 and had reached 30 years from onset of work exposure were invited to appear for a comprehensive medical examination. Twelve cases of lung cancer and two cases of pleural mesothelioma, previously undiagnosed, were discovered during the survey. The cross sectional prevalences of newly discovered cancer and AARA were similar. No clinical features, aside from possible radiographic appearance, were capable of distinguishing AARA from cases of lung cancer or mesothelioma in this survey.
