Active clinical trials for "Prostatic Neoplasms"

The purpose of this research study is to determine if giving men with early stage (Grade 1-2) prostate cancer dietary supplement from soybeans called isoflavones, will change their blood hormone levels. Isoflavones are substances found in a high concentration in soybeans that are converted in the intestines to hormone-like compounds which are similar to estrogen. They are also thought to have cancer fighting properties. Clinical trials suggest that isoflavones can increase certain sex hormones, which results in the slower production of prostate cancer cells. This study will determine if adding isoflavones (supplied as Prevastein HC®) 80 mg/day in a pill form can change your risk factors that cause early stage prostate cancer to progress to more advanced disease.

The purpose of this study is to measure the benefit of sorafenib in patients with a rising PSA after treatment with radiation therapy or surgery who are NOT receiving with androgen ablation therapy.

This study is being done to test the safety of a single high-dose of radiation therapy before radical prostatectomy (removal of the prostate). The investigators want to find out what effects, good and/or bad, the radiation will have on men undergoing prostatectomy. The investigators are especially interested in men who are at risk for having cancer cells that have spread outside the prostate.

The purpose of this study is to evaluate the role and effectiveness of conversion to sirolimus versus CNI reduction in renal transplant patients with prostate cancer.

This study evaluates the efficacy of a tailored telephone intervention to promote informed decision making about prostate cancer testing among predominantly immigrant black men.

Open-label exloratory pharmacodynamic and pharmacogenomic study to evaluate teh biologic effects of 3 dose levels (1mg, 5 mg, and 15 mg) of temsirolimus administered orally once daily for approximately 4 weeks (+/- 2 weeks) before prostatectomy

The purpose of this study is to see if darbepoetin alfa is an effective treatment for anemia in prostate cancer patients and, if so, what dose is most effective. Sometimes prostate cancer patients have low red blood cell counts (low hemoglobin) from various treatments they are receiving, such as chemotherapy. The red blood cells deliver oxygen to the tissue. This then helps give the patient more energy.

This is a randomized study evaluating the effectiveness and direct effect a commercial soy supplement has on prostate cancer and normal prostate tissue. Patient will be randomized it either receive placebo or a commercial soy supplement for 2-4 weeks prior to the planned surgery for treatment of their prostate cancer. Patient's blood and prostate tissue will be evaluated to determine the effects of the soy supplement on the prostate tissue.

The primary objective of this study is to evaluate the effect of erlotinib on the PSA response rate in patients with non-metastatic prostate cancer and a rising PSA on androgen deprivation therapy. The secondary objectives are to evaluate the effect of erlotinib on the duration of PSA response, to evaluate the effect on the time to PSA progression, to evaluate the toxicity of erlotinib in this patient population, and lastly, to correlate the effect of erlotinib with various epidermal growth factor receptor (EGFR)-related proteins using baseline immunohistochemical (IHC) studies on tissue blocks and peripheral blood mononuclear cells.

To effectively treat prostate cancer, doctors need an accurate view (via X-rays) of the prostate gland during radiation therapy. To help improve this view, doctors may insert gold markers called fiducials into the prostate by placing hollow gold needles through the rectum and moving a fiducial through each needle. The purpose of the study is to determine whether an MRI scan can help doctors improve their placement of these needles. Fifteen men will participate in this study. Patients will take the antibiotic levofloxacin for two days prior to the placement of the fiducials, then will have a small enema and another dose of the antibiotic on the morning of the procedure. After being anesthetized, patients will have an antenna-like tube placed into the rectum and have MRI images taken of the area. The doctor will then use these scans to place four fiducials into the prostate. The procedure will require approximately 45 minutes. Patients will be allowed to go home the same day of the procedure, which will be followed by a seven-week course of standard radiation therapy. Prior to their participation in this study, patients will undergo the following evaluations: a physical exam, blood work, urine tests, and, if appropriate, an MRI or bone scan.
