Physicians have known since 1941 that testosterone suppression benefits patients with symptomatic metastatic prostate cancer.[1] The pioneering study in this regard showed that estrogen therapy achieved comparable efficacy to castration by improving acid and alkaline phosphatase levels associated with relief of cancer-related symptoms. More than 6 decades later, however, many of the therapies subsequently developed for achieving androgen deprivation still suffer from serious limitations.
