Brief Summary
This is a prospective, multicentre, open-labelled, randomized controlled trial comparing the efficacy of immediate versus deferred androgen deprivation therapy (ADT) using goserelin (Zoladex®) in men with recurrent prostate cancer after radical radiotherapy. 1100 patients will be accrued from participating Canadian Urological Oncology Group sites in an estimated time of 3 years. First analysis is planned for 7 years after study recruitment is completed.

Time to androgen independent disease (AID). AID is defined as the time from randomization to AID or last follow-up.
Every 6 months
Secondary Outcomes (4)
Time to complications of advanced malignancy (CAM) and number of CAMs experienced are secondary outcome measures.
Every 6 months

Continuous goserelin, 12 week (10.8 mg) depot, will be used as ADT for both study arms. It is supplied as a sterile syringe for subcutaneous use.
Eligibility Criteria
You may qualify if:
- Males over 18 years of age with histological confirmation of adenocarcinoma of the prostate.
- Biochemical progression after radical radiotherapy with a total prostate dose \> 52 Gy.
- In patients without previous radical prostatectomy, biochemical progression is defined as PSA in the range of nadir + 2 ng/mL (Phoenix definition) to ≤ 6 ng/mL (this PSA must be within 30 days of randomization).
- In patients with previous radical prostatectomy, biochemical progression is defined as a rising PSA (at least 2 values) in the range of 0.4 ng/mL to ≤ 3 ng/mL (most recent PSA must be within 30 days of randomization).
You may not qualify if:
- Patients who are within 4 years of their brachytherapy implantation date.
- Patients with medical conditions in which goserelin or bicalutamide is contraindicated in the opinion of the supervising oncologist or urologist.
- Patients with another active malignancy or malignancy treatment within 5 years (basal or squamous cell skin cancers are not excluded from this trial).
- Patients with geographic inaccessibility precluding them from necessary follow-up.
- Failure to provide written informed consent.
