【 摘 要 】

This study provides the cancer mortality pattern for a cohort of 10,017 electric power plant workers from 1978 to 1994. Standard mortality ratio (SMR) analysis showed lower mortality from all causes (0.47: 0.43-0.51) and from all groups of causes including neoplasms (0.73: 0.60-0.90) among these workers, in comparison with the same sex and age bracket in Rio de Janeiro. In relation to specific cancer sites, standard cancer mortality ratios (SCMRs) greater than one were observed for neoplasms of the small bowel (10.35: 3.34-32.09), gallbladder (2.64: 0.99-7.03), pancreas (1.83: 0.91-3.66), kidney (2.91: 1.39-6.10), and bladder (2.60: 0.58-4.12), as well as for melanoma (1.82: 0.46-7.28). Important limitations were the workers' relatively young age and the short period of time since job admission (less than 15 years). The small number of deaths for each anatomic site led to instability in the study results, with many non-significant SCMRs and wide confidence intervals. Due to these limitations, study results are difficult to interpret in light of currently available evidence.
