    Selenium supplementation, baseline plasma selenium status and incidence of prostate cancer: an analysis of the complete treatment period of the Nutritional Prevention of Cancer Trial

    Duffield-Lillico AJ, Dalkin BL, Reid ME, Turnbull BW

    Published in BJU International

    Methodology

    Randomized placebo-controlled trial of selenium 200 mcg daily in 1312 residents of the eastern USA, originally designed to test prevention of recurrent nonmelanoma skin cancer, with analysis over the complete blinded treatment period.

    Key Findings

    Selenium did not prevent recurrent nonmelanoma skin cancer (the trial primary aim); the prostate cancer reduction was a secondary finding confined to certain baseline subgroups.

    Conclusions

    Selenium supplementation cannot be recommended for skin cancer prevention; skin cancer endpoints were not improved.

    Limitations

    Secondary analyses; single geographic region; selenium-replete populations may differ.
