Abstract
A recent animal experiment suggests that gasoline exposure may be a cause of human kidney cancer. This is a literature review to see whether there is any epidemiologic support for these animal findings. Trends and geographic patterns in gasoline consumption and kidney cancer mortality are moderately supportive of a relationship, although this cannot be considered important evidence for a causal relationship. Most other ecological correlations are not supportive of a relationship. Eleven oil refinery populations and one population of petroleum products distribution workers have been studied. These studies taken as a group do not appear to support the notion of a relationship between gasoline exposure and kidney cancer. However, most were not designed or analyzed with this hypothesis in mind. An examination of these data which attempts to consider the ages of the populations studied provides some evidence of a small kidney cancer excess among older workers or among workers exposed for long periods. Because of the importance of gasoline and the potential for exposure by the public further study of exposed populations is needed.
