Castrate serum T levels and prostate cancer-specific mortality

A few weeks ago, a Letter to the Editor in the New England Journal of Medicine focused on the significance of castrate levels of serum testosterone (serum T) in men being treated with LHRH agonists for advanced forms of prostate cancer. … READ MORE …

Assessment of serum T levels in men on androgen deprivation therapy

A paper in a forthcoming issue of European Urology recommends strongly that clinicians should monitor serum testosterone (serum T) levels during androgen-deprivation therapy (ADT) in men with prostate cancer. … READ MORE …

Some recent studies (e.g., Skinner and Schwartz) have suggested an association between high levels of serum calcium and a high risk of prostate cancer death. Now an analysis of historical specimens from a large Swedish database suggests that there is no reason to believe that there is any association between serum calcium and prostate cancer risk. … READ MORE …
