Effect of androgen deprivation therapy on cardiovascular function in Chinese patients with advanced prostate cancer:...

Androgen deprivation therapy (ADT) is the standard treatment for advanced prostate cancer, but its effect on cardiovascular and metabolic function in Asian patients is still inconclusive. We prospectively assess the effects of ADT on 36 patients with advanced prostate cancer, with reference to another 24 prostate cancer patients not requiring ADT, for 2 years. Patients' anthropometric, metabolic and vascular parameters were assessed every six-monthly. The baseline parameters of the two groups were comparable. There was a significant negative effect of the usage of ADT on the changes in BMI (p = 0.020), waist to hip ratio (p = 0.005), body fat percentage (p = 0.012), and high-density-lipoprotein (p = 0.012). ADT-patients were 4.9 times more likely to have metabolic syndrome at 24 months. (CI 0.889-27.193, p = 0.068). The Framingham risk score (p = 0.018) and pulse-wave-velocity (p = 0.024) for ADT-group were also significantly higher than controls, which signified increase in cardiovascular risk. Although there was no statistically significant difference in ischemic cardiovascular events between two groups, a trend for more events in ADT-group was observed. Therefore, Asian patients have increased cardiovascular and metabolic risks after being treated with ADT for two years. Appropriate counselling and monitoring of associated complications with ADT are essential.
