Case-Control Study of Cancer of the Kidney in Knox County, Maine.
A significantly elevated occurrence of kidney cancer mortality had been reported among white male residents of Knox County, Maine; death certificate records were examined to assess any possible occupational relationship to these deaths. The cohort included 46 kidney cancer cases, and 184 comparison subjects were chosen. There were 27 subjects for whom no industry could be assigned and nine for whom no occupation could be determined. There was only one occupation, engineers, which emerged with a statistically elevated cancer risk. Of the five deaths among engineers, no common workplace exposure could be found. The five included a civil engineer, a textile industry safety engineer, a mechanical engineer for a drug manufacturing firm, and two marine engineers. The authors conclude that there is no evidence for a link between kidney cancer incidence and workplace exposures in Knox County. The possible connection with cigarette smoking was also ruled out as there was not an increase in mortality rate for lung cancer among white males in this county during this same time period.
