Abstract
Selenium is a trace element that is essential to the human diet. Deficiency states have been described in both animals and humans. In addition, selenium compounds have demonstrated toxicity in humans, as well as in human tissues in culture. As early as 1956, one form of selenium was used as an antineoplastic agent in humans with some demonstrated activity. Recently, evidence in both tumor-bearing animals and human tumor cells in culture have confirmed an antitumor effect of potential clinical benefit. The mechanism of this cytoxic effect appears, at least in part, to relate to the property of some forms of selenium to oxidize critical sulfhydral groups in the cell. Evidence for this, and the resulting implications for the use of selenium in anticancer treatment, is presented in this manuscript.
