Benefits of intermittent/continuous androgen deprivation in patients with advanced prostate cancer

In 1941 Huggins described the effect of castration on prostate cancer. gonadotropin-releasing hormone (GNRH) analogues were introduced in 1985. Complete androgen blockade (association of GNRH analogue with antiandrogen) was introduced by Fernand Labrie to achieve suppression of suprarenal testosterone. Long time androgen deprivation lead to androgen independence of the prostate cancer cell. Our principal aim was to demonstrate longer survival rates on prostate cancer patients with intermittent androgen deprivation.

82 patients in the Urology Department of Vasile Goldis West University Arad were included into two groups, with continuous and intermittent androgen deprivation.Treatment efficiency was assessed by the level of testosterone and PSA.Adverse events (AE) and serious adverse events were reported according to Common Terminology Criteria of Adverse Events (CTCAE) of the National Cancer Institute (NCI).

Evolution towards castrate resistant prostate cancer: 12.5% from the intermittent androgen deprivation group and 23.8% from the continuous androgen deprivation groupMortality rate: 15% of patients from the intermittent androgen deprivation group; 19% of patients from the continuous androgen deprivation group.

Better quality of life (Qol) in periods without treatment due to testosteron recovery;Less AE's and metabolic syndrome (MS) related complications;Better survival and longer time of disease control andCost reduction.
