A retrospective follow-up study was conducted to evaluate mortality and cancer incidence between 1954 and 1976 among 1,792 white male production workers employed for at least 2 years at a tire manufacturing plant. There were no marked excesses in overall or site-specific cancer deaths or incident cases. Compared to U.S. white males, men employed for at least 10 years experienced small increases in deaths from cancers of the large intestine, pancreas, and lung. Results obtained by comparing observed incident cancer cases to the numbers expected based on age- and calendar time-specific incidence rates of Connecticut males also suggested excesses of these three malignancies. These findings were based on small numbers and therefore do not necessarily indicate causal associations between cancer excesses and employment in the rubber tire industry. However, because the workers studied comprised a relatively young population that may not have experienced the full impact of carcinogenic occupational exposures, further follow-up is warranted.
