PURPOSE: Prostate cancer (PCa) is one of the most common cancers in men. Men with recurrent or metastatic
PCa are treated with androgen-deprivation therapy (ADT), resulting in profound hypogonadism. Because male
hypogonadism is a risk factor for metabolic syndrome and men with PCa have high cardiovascular mortality, we
evaluated the prevalence of metabolic syndrome in men undergoing long-term ADT.
PATIENTS AND METHODS: This
was a cross-sectional study. We evaluated 58 men, including 20 with PCa undergoing ADT for at least 12
months (ADT group), 18 age-matched men with nonmetastatic PCa who had received local treatment and were
recently found to have an increasing prostate-specific antigen (non-ADT group), and 20 age-matched controls
(control group). Men in the non-ADT and control groups were eugonadal. Metabolic syndrome was defined
according to the Adult Treatment Panel III criteria.
RESULTS: Mean age was similar among the groups. Men on
ADT had significantly higher body mass index and lower total and free testosterone levels. The prevalence
of metabolic syndrome was higher in the ADT group compared with the non-ADT (P < .01) and control (P = .03)
groups. Among the components of metabolic syndrome, men on ADT had a higher prevalence of abdominal obesity
and hyperglycemia. Androgen-deprived men also had elevated triglycerides compared with controls (P = .02).
The prevalence of hypertension and low high-density lipoprotein levels were similar.
CONCLUSION: These data
suggest that metabolic syndrome was present in more than 50% of the men undergoing long-term ADT,
predisposing them to higher cardiovascular risk. Abdominal obesity and hyperglycemia were responsible for
this higher prevalence. We recommend prospective studies to further delineate this association.
