An Alternative to A Fixed Schedule In Management Of Prostate Cancer
Testosterone-Guided Schedule of Androgen Deprivation Therapy (ADT) as an Alternative to A Fixed Schedule In Management Of Prostate Cancer

The male sex-hormone called testosterone is known to play a key role in the growth of prostate cancer. The usual treatment for the disease involves suppression of hormones (testosterone) by anti-hormonal treatment for an unknown period of time until the cancer progresses. This anti-hormonal treatment usually consists of injections every three months with an LHRH(Leutinizing Hormone-Releasing Hormone) agonist and a short course of anti-androgen pills, which together help to lower the production of testosterone. Long-term hormonal treatment has potentially serious side effects and is expensive.

In this study, hormonal treatments will be with held from those patients eligible and willing to participate. The aim of this study is to see if we can decrease the amount of hormone injections that patients require. This might lead to a decreased side effects(such as decrease in bone health, cardiovascular problems and metabolic syndrome which occurs when several health conditions happen at the same time and can lead to an increased risk of heart disease, stroke and diabetes) as well as to decrease the cost of hormonal therapy to treat prostate cancer.
