The incidence of @entity5 among 4480 shipyard workers, including 861 welders, was investigated for a potential relationship between exposure to welding fumes and @entity2 . A subcohort of 3150 workers with information on previous work history was studied separately. This investigation is a historical prospective cohort study. Environmental air samples were collected in 1973, 1977, and 1989. Information on smoking habits was surveyed in 1976 and 1984. The employment work histories were collected from the personnel register. There were 411 observed cancers of all sites versus 387.5 expected, and 45 cases of @entity2 versus 51.3 expected. Nine cases of @entity2 were found among the welders versus 7.1 expected. Among 310 former seamen with welding experience, there was 1 case of @entity2 versus 2.1 expected. These shipyard workers showed no excess risk of @entity2 . @entity286 smoking and asbestos exposure are potential confounders in the study. There was no clear relationship between exposure to welding fumes and @entity2 , but welders with the longest experience had a relative risk of 1.9 for @entity2 . The differences in @entity2 incidence among the different shipyard workers could not be attributed to differences in recruitment patterns or previous work history.
