Partial androgen suppression consequent to increased secretion of adrenal androgens in a patient with prostate cancer treated with long-acting GnRH agonists. [JOURNAL ARTICLE]
Prostate Cancer Prostatic Dis 2008 Jun 24.
We present a case report of a patient with prostate cancer who failed to demonstrate consistent testosterone suppression to castration levels and incomplete suppression of serum prostate-specific antigen, although treated with gonadotropin releasing hormone agonists for 48 months. Serum dehydroepiandrosterone , dehydroepiandrosterone sulphate, as well as the androgen metabolite, androsterone glucuronide, were elevated compared to the other patients. The present data suggest that those prostate cancer patients who have even marginally elevated adrenal androgens may especially benefit from combined androgen blockade.Prostate Cancer and Prostatic Diseases advance online publication, 24 June 2008; doi:10.1038/pcan.2008.15.
