Active clinical trials for "Prostatic Neoplasms"

Prostate cancer patients treated with LHRH agonists (e.g., leuprolide) lose bone mineral density. This is similar to post-menopausal osteoporosis. Risedronate is approved to prevent osteoporosis. We hypothesize that risedronate may also be effective in prostate cancer patients treated with LHRH agonists.

RATIONALE: Chemoprevention is the use of certain drugs or substances to keep cancer from forming, growing, or coming back. The use of lycopene, a substance found in tomatoes, may keep prostate cancer from forming in patients at high risk of developing prostate cancer. PURPOSE: This phase I trial is studying the side effects and best dose of lycopene in preventing prostate cancer in patients who are at high risk of developing prostate cancer.

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of fish oil and/or green tea may prevent prostate cancer. PURPOSE: This randomized clinical trial is studying how well a fish oil and/or green tea supplement works in preventing prostate cancer in patients with prostatic intraepithelial neoplasia or who are at risk for developing prostate cancer.

Hypoxia (low oxygen level) is know to be present in many tumors and may strongly influence the success of treatment and the progression of disease in prostate cancer. The method used to measure tumor oxygen levels in prostate cancer is to place a needle in the prostate itself through the rectum. Blood oxygen level dependent imaging (BOLD MRI) is a special MRI technique that allows indirect assessment of oxygen levels in blood. This technique is non-invasive, involving no needles. BOLD has not been applied in humans in prostate cancer. The purpose of this study is to develop a MRI-BOLD technique that allows us to non-invasively measure changes related to tumor hypoxia in prostate cancer. This technique may provide information that will be an independent predictor of patient survival, tumor recurrence and likelihood of treatment response in prostate cancer

The primary goal of this study is to develop and evaluate a print-based method of patient education with a decision tool that is designed to provide detailed information about prostate cancer and to clarify patient preferences and values, ultimately assisting men in making an informed screening decision.

This 4-year study will compare how safe and effective an oral investigational medicine is (compared to placebo) in preventing the development of prostate cancer in men that are defined by the study entrance criteria as being at an increased risk for prostate cancer. Study visits to the clinic will occur every 6 months for up to 4 years (10 clinic visits), and a prostate biopsy will be performed at 2 and 4 years of treatment.

RATIONALE: Soy protein supplement may prevent or delay the development of prostate cancer in patients who have elevated prostate-specific antigen (PSA) levels. PURPOSE: Randomized phase II trial to determine the effectiveness of soy protein supplement in preventing prostate cancer in patients who have elevated PSA levels.

The purpose of this research study is to test a new treatment for prostate cancer. We have been exploring the use of cytokine (immune stimulating) gene therapy by directly injecting a virus which produces a cytokine called interleukin-12 (IL-12) into the prostate gland to control tumor growth. We propose to explore the use of adenovirus-mediated human interleukin-12 (Ad.hIL-12) in patients with recurrent non-metastatic prostate cancer following radiation therapy in a Phase I trial. Participants will be placed in rising dose groups with the primary endpoint of learning the maximum dose that can safely be given by injection directly into the prostate gland. Toxicity will be determined through physical examination, laboratory values, and blood levels of cytokines. Evidence of an immune response against prostate proteins will also be monitored. If the treatment works, the cancer will shrink or not grow. This will be monitored by prostate specific antigen (PSA) levels in the blood. However, we do not know if this treatment will be effective. If the PSA continues to rise after treatment, participants will be taken off study and offered other treatment. There is no compensation for participation in this research study. There will be no charge for the treatment with gene therapy or the monitoring associated with this research study. Monitoring will occur in a specially designated clinical research center.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Randomized phase I trial to determine the effectiveness of genistein in treating patients who have stage II, stage III, or stage IV prostate cancer.

RATIONALE: New imaging procedures such as CT-on-rails™ may improve the ability to pinpoint the location of the tumor and decrease radiation therapy damage to healthy tissue. PURPOSE: This phase I/II trial is studying how well computed tomography (CT) scans using CT-on-rails™ work in pinpointing the location of the tumor in patients with prostate cancer.
