Bone is the most common site of metastases in prostate cancer and bone complications cause substantial morbidity to this population. Phase III studies have shown that zoledronic acid is effective in decreasing the morbidity associated with bone metastases. Zoledronic acid (ZA) is generally well tolerated but may have side effects such as hypocalcemia, renal impairment and osteonecrosis of the jaw. Administration of ZA as infrequently as once yearly is sufficient to prevent osteopenia or osteoporosis. The optimal treatment interval is unknown, but the drug is often empirically administered every 3-4 weeks. The cost of such treatment is high, and the risk of exposing patients (especially those at low risk) to potential serious side effects with uncertain benefit warrants investigation. This study will determine the duration of suppression of bone turnover in prostate cancer patients with bone metastases following a single infusion of Zoledronic Acid and its effect on quality of life.

The purpose of this study is to assess the efficacy and tolerability of zoledronic acid in preventing skeletal-related events in patients with prostate cancer
This study aims to determine whether early treatment with zoledronic acid, that is given during the early phase of advanced prostate cancer, will be more efficacious than delayed treatment
This research study is being done to find out if giving zoledronic acid before the cancer spreads to the bone is better or worse than standard treatment. The study will also compare the e...
The management of bone lesions from advanced solid tumors and multiple myeloma typically includes use of a bone-modifying agent to reduce the risk of skeletal-related events. Recent data demonstrate t...
Short-term androgen suppression and radiotherapy versus intermediate-term androgen suppression and radiotherapy, with or without zoledronic acid, in men with locally advanced prostate cancer (TROG 03.04 RADAR): 10-year results from a randomised, phase 3, factorial trial.
The optimal duration of androgen suppression for men with locally advanced prostate cancer receiving radiotherapy with curative intent is yet to be defined. Zoledronic acid is effective in preventing ...
In recent years, therapeutic advances, together with new medication sequences and combinations, have improved outcomes for prostate cancer. For a long time, androgen deprivation therapy (ADT) has been...

An androstene derivative that inhibits STEROID 17-ALPHA-HYDROXYLASE and is used as an ANTINEOPLASTIC AGENT in the treatment of metastatic castration-resistant PROSTATE CANCER.
A synthetic long-acting agonist of GONADOTROPIN-RELEASING HORMONE. Goserelin is used in treatments of malignant NEOPLASMS of the prostate, uterine fibromas, and metastatic breast cancer.
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
A lipoxygenase metabolite of ARACHIDONIC ACID. It is a highly selective ligand used to label mu-opioid receptors in both membranes and tissue sections. The 12-S-HETE analog has been reported to augment tumor cell metastatic potential through activation of protein kinase C.
