An update of a cohort study of 4855 employees at a Paulsboro, New Jersey refinery was conducted to further examine mortality patterns.
The earlier study investigated refinery workers employed for a minimum of 1 year between I January 1946 and 1 January 1979.
The vital status of these workers was ascertained through 1979.
The update extended enrollment in the study and vital status follow-up for an additional 8 years (1980-1987).
As in the previous study, mortality from all causes [standardized mortality ratio (SMR)=87 ; 95% confidence interval (95% CI) : 83-91] was significantly lower than expected compared with the general population.
Total cancer mortality was also lower than expected (SMR=96 ; 95% CI : 86-106).
A borderline significant mortality increase in prostatic cancer was found (SMR=144 ; 95% CI : 106-190).
This increase was similar to the nonsignificant increase reported in the original study (SMR=135 ; 95% CI : 90-196).
The excess was of comparable magnitude among white males and nonwhite males, although it was not significant for the latter.
Detailed analysis indicated that the prostatic cancer was not likely to be related to employment at the refinery.
Mortality from lymphatic and hematopoietic cancers was similar to the expected mortality.
Mortality from overall leukemia was as expected and detailed analyses by specific cell type showed no increase. (...)
