Active clinical trials for "Prostatic Neoplasms"

RATIONALE: Calcitriol and dexamethasone may slow the growth of prostate cancer cells. PURPOSE: This randomized phase II trial is studying how well giving calcitriol together with dexamethasone before radical prostatectomy works in treating patients with localized stage II or stage III adenocarcinoma (cancer) of the prostate.

To identify the proportion of patients remaining medically castrated (testosterone level < 50 ng/dL) on Day 240 following two administrations of a 4-month sustained-release (SR) formulation of triptorelin.

The primary objective of the study is to determine the response rate to TPI 287 in patients with metastatic, hormone-refractory prostate cancer who have had one prior taxane regimen.

The main purpose of this study is to try to find out whether adding chemotherapy to the standard treatment for your stage of prostate cancer is more effective than the standard treatment by itself. The kind of treatment that most physicians would consider standard for this stage of prostate cancer is radiation therapy alone, possibly in combination with hormonal therapy. In this study, all patients will receive chemotherapy and radiation therapy. It is hoped that chemotherapy will be found to provide additional benefit, but chemotherapy has significant side effects. The use of chemotherapy is experimental in prostate cancer; it needs to be tested to determine if it is beneficial and to find out more about the side effects of the two different treatments. This study is to determine the effects, good and/or bad, of adding chemotherapy to radiation therapy as "salvage" treatment for recurrent prostate cancer after surgery.

The purpose of this study is to see if giving zoledronic acid three times a year is as effective as five times a year, in increasing bone strength in men with prostate cancer. All participants will receive the active drug but half will receive drug every 6 months and the other half will receive drug every 3 months. Both patient and doctor will know which treatment a patient is receiving. After 1 year of treatment bone strength will be measured with scans and compared to the strength at the start of the study. All participants will stop receiving the drug after 1 year and will be seen back in the clinic, annually for another 2 years for follow-up.

The purpose of the study is to evaluate the efficacy and the safety of AMT2003 in cancer patients with advanced disease. The primary evaluation criterion is clinical benefit response.

RATIONALE: Ultrasound therapy kills tumor cells by heating them to several degrees above body temperature. This treatment may be effective for prostate cancer. PURPOSE: Phase III trial to determine the effectiveness of ultrasound therapy in treating patients who have stage I or stage II prostate cancer that has recurred following radiation therapy.

RATIONALE: Ketoconazole may suppress the production of hormones and may interfere in the growth of prostate cancer cells. Alendronate sodium may be effective in preventing bone metastases and bone pain associated with prostate cancer. It is not known if ketoconazole is more effective with or without alendronate sodium. PURPOSE: Randomized phase II trial to study the effectiveness of ketoconazole with or without alendronate sodium in treating patients who have metastatic prostate cancer.

RATIONALE: Inserting the gene for interleukin-2 into a person's cancer cells may improve the body's ability to fight cancer. Using Leuvectin to deliver this gene may be an effective treatment for prostate cancer. PURPOSE: Phase II trial to study the effectiveness of Leuvectin followed by surgery in treating patients who have stage II or stage III prostate cancer.

RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as aminoglutethimide or ketoconazole may stop the adrenal glands from producing hormones. Combining hydrocortisone with either aminoglutethimide or ketoconazole may be an effective treatment for prostate cancer. PURPOSE: Phase II trial to study the effectiveness of combining hydrocortisone with either aminoglutethimide or ketoconazole in treating patients who have localized stage IV prostate cancer.
