Cause specific mortality was investigated in a cohort of insulators employed by a company which operated in various parts of Italy. Follow-up covered the years 1960-1996. The cohort, which included 893 subjects, was derived from company files of relatively poor quality, which resulted in a high rate of lost to follow-up (10.1%) and of deaths with unknown cause (12.4%). The mortality experience of the cohort was contrasted with that of the Italian population. Overall mortality (SMR 141, 90% CI 118-167, 97 observed), and cancer mortality (SMR 165, 90% CI 123-216, 38 observed) were significantly increased. Among neoplasms, significant increases were observed for lung cancer (SMR 202, 90% CI 124-311, 15 observed), pleural neoplasms (SMR 2667, CI 90% 911-6103, 4 observed), and peritoneal neoplasms (SMR 1853, 90% CI 329-5832, 2 observed). The excess mortality for lung cancer was especially pronounced in subjects with latency time longer than ten years (SMR 237.1, 90% CI 140-377, 13 observed).
