Summary
Brief summary (as posted)
Radical prostatectomy is used to treat early prostate cancer in otherwise well men, but is followed by later cancer relapse in 1 in 4 cases. This study aims to see if post-operative adjuvant therapy with a combination of zoledronic acid and docetaxel might help reduce relapse in such cases. Patients will be randomized to receive the adjuvant combination therapy or no therapy. All patients will be monitored closely for signs of relapse and treated appropriately with conventional salvage therapy.
