Storage of endocrine disruptors. Endocrine disruptors (ED) are thought to be involved in prostate cancer (10). However, epidemiologic evidence of a positive link between environmental exposures to ED is limited. Two studies using blood plasma or abdominal fat for monitoring persistent pollutants have shown positive associations with PCa risk (transchlordane, beta-hexachlorocyclohexane, trans-nonachlore, dieldrine, and polychlorinated biphenyl 153) (11, 12). A recent study carried out in French West Indies showed that chlordecone, an organochlorine pesticide with well defined estrogenic properties, increases the risk of PCa, and is associated with an aggressive form of the disease in subjects with a positive family history of PCa (13).
