Changes to This Summary (04/13/2015)

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.


Revised text to state that two studies have examined men undergoing androgen deprivation therapy who were randomly assigned to receive a placebo or an isoflavone supplement for 12 weeks. Also revised text to state that neither study found an improvement in side effects following isoflavone treatment, compared with placebo (cited Vitolins et al. as reference 40).

Vitamin D

Added text to state that in one case-control study of men who had undergone prostate biopies, men who had lower vitamin D levels before biopsy were more likely to have cancer detected at biopsy than did men whose prebiopsy vitamin D levels were not lower.

Multicomponent Therapies

Added this new section.
