Summary

The prostate gland is a clinically important male accessory sex gland and vital for its production of semen. Prostate cancer (PCa) is now ranked 3th in annual incidence of male cancer and ranked 5th for cancer-related death in men in Hong Kong which accounts for about 10.9 deaths per 100,000 persons. Its incidence is rising rapidly, almost tripled in the past 10 years. Despite the improvement in awareness of the disease and also increasing use of serum prostate specific antigen, many patients still presented at a late stage that beyond cure by local therapy. Together with those patients suffered recurrent disease after local therapy, many PCa patients required the use of androgen deprivation therapy (ADT) for the control of disease.

However, unlike other malignancy, PCa is characterized by its slow progression nature and even for metastatic disease the 5-year survival is upto 20%. Therefore, while ADT can provide effective control of disease, there are increasing evidences suggesting that it can also result in many adverse effects in the patients, and these effects are particular important due to the long survival of these patients. From the western literature, the adverse effects can be quite diverse. Classical side effects after ADT include mood changes, hot flushes, change in cognitive function, loss of libido, erectile dysfunction, osteoporosis and pathological fracture, insulin resistance and increase in risk of cardiovascular related mortality.

Unfortunately information regarding the side effects of ADT in Asian population is scanty and inconclusive. Therefore, there is a need to have more information on the adverse effect profiles related to ADT in Asian population.

This is a multicentre, prospective, observational, non-interventional study to assess the clinical effectiveness, cardiometabolic and skeletal effects of the various type of ADT - bilateral orchidectomy, GnRH agonist, and GnRH antagonist - in men with advanced prostate cancer over a minimum of 1-year observation period.

Conditions

Interventions

PROCEDURE

Androgen deprivation therapy - bilateral orchidectomy

Androgen deprivation therapy (ADT) is a kind of hormone therapy for prostate cancer. The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from affecting prostate cancer cells. It can be surgical, i.e. bilateral orchidectomy, or medical, i.e. GnRH agonist or GnRH antagonist.

DRUG

Androgen deprivation therapy - GnRH agonist

Androgen deprivation therapy (ADT) is a kind of hormone therapy for prostate cancer. The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from affecting prostate cancer cells. It can be surgical, i.e. bilateral orchidectomy, or medical, i.e. GnRH agonist or GnRH antagonist.
