BACKGROUND
The role of androgen deprivation therapy in prostate carcinoma is controversial in earlier stages of disease. The authors examined the time trends and patterns of use for androgen deprivation in the form of gonadotropin-releasing hormone (GnRH) agonists or orchiectomy, in population-based tumor registries.
METHODS
Data were obtained from the linked Surveillance, Epidemiology and End Results-Medicare database. A total of 100,274 men with prostate carcinoma diagnosed from 1991 through 1999 were selected. The main outcome was the proportion of men who received ≥ 1 dose of a GnRH agonist in the first 6 months of diagnosis. This was plotted by year and stratified for age, grade, stage as well as primary versus adjuvant usage. Multiple logistic regression was used to examine predictors of GnRH agonist use in the subset of patients with localized cancer.
RESULTS
There was a consistent increase in GnRH agonist use by year for all ages, stages, and grades. Even in men ≥ 80 years with localized stage and low to moderate grade tumors, primary GnRH agonist use increased over the study period, from 3.7% in 1991 to 30.9% in 1999 (P < 0.001). The multivariable analysis showed that significant variability in GnRH agonist use existed among SEER geographic regions.
CONCLUSIONS
The use of GnRH agonists for prostate carcinoma increased dramatically during the 1990s. This increase occurred across all stages and histologic grades of prostate carcinoma, and was greatest in patients ≥ 80 years. Cancer 2005. © 2005 American Cancer Society.read more

Diabetes and Cardiovascular Disease During Androgen Deprivation Therapy for Prostate Cancer
TL;DR: GnRH agonist treatment for men with locoregional prostate cancer may be associated with an increased risk of incident diabetes and cardiovascular disease and the benefits of GnRH agonists should be weighed against these potential risks.

TL;DR: The introduction of an effective blood test, prostate specific antigen (PSA), has made it possible to diagnose more and more men in an earlier stage where they can be offered potentially curative treatments, and this is the subject of the EAU guidelines on prostate cancer.

Combined Resistance and Aerobic Exercise Program Reverses Muscle Loss in Men Undergoing Androgen Suppression Therapy for Prostate Cancer Without Bone Metastases: A Randomized Controlled Trial
TL;DR: A relatively brief exposure to exercise significantly improved muscle mass, strength, physical function, and balance in hypogonadal men compared with normal care and could be recommended for patients undergoing AST as an effective countermeasure to these common treatment-related adverse effects.
