Active clinical trials for "Prostatic Neoplasms"

The main purpose of this study is to find out whether adding radiation therapy to the standard treatment of chemotherapy for prostate cancer is tolerated well and is more effective than the standard treatment of chemotherapy alone

To evaluate the clinical impact of an online video simulator during the learning period of laparoscopic radical prostatectomy.

This phase I trial is studying the best way to give omega-3 fatty acids in treating patients with advanced prostate cancer. Omega-3 fatty acids may slow disease progression and may be an effective treatment for patients with advanced prostate cancer

Primary Goal The study's primary goal is to assess the safety of the BioProtect biodegradable balloon implant and implantation procedure, in prostate cancer subjects undergoing routine radiation therapy (XRT) treatment. Safety of the BioProtect device will be assessed by reporting adverse events. Secondary Goal The study's secondary goal is to evaluate the effectiveness of the BioProtect biodegradable balloon implant in prostate cancer subjects undergoing routine XRT treatment. Effectiveness will be assessed in terms of increased distance between anterior rectal wall and prostate and noticeable reduction of isodose to the rectum.

Background: Prostate cancers are difficult to see on most imaging studies such as X-rays, computed tomography (CT) scans, conventional magnetic resonance imaging (MRI) scans and conventional positron emission tomography (PET) scans. An experimental radioactive tracer called 11C-acetate accumulates in prostate tumor cells and may help find prostate cancers more accurately than other imaging methods. Objectives: To determine the accuracy of prostate tumor imaging using the tracer 11C-acetate. Eligibility: Patients 18 years of age and older who are undergoing surgery for localized prostate cancer at the National Institutes of Health (NIH) Clinical Center. Design: Patients have a positron emission tomography (PET scan). For this test, an intravenous (IV) line is placed in the patient's arm and the patient lies on a table inside the donut shaped scanner. (11)C-acetate is injected into the vein through the catheter and images of the lower pelvis and abdomen are obtained over 30 minutes. Patients have an endorectal coil MRI scan. For this test, a tube is placed in the rectum, just behind the prostate, to increase the amount of signal received by the magnetic resonance (MR) unit. Other coils may be wrapped around the pelvis to further improve the quality of the scan. The patient lies on the scanning table for about 75 to 90 minutes while images are obtained. During the scan, a contrast agent called gadolinium is injected through an intravenous (IV) line to brighten the images.

RATIONALE: Selenomethionine may slow the growth of prostate cancer. Giving selenomethionine before surgery or internal radiation therapy may be an effective treatment for prostate cancer. PURPOSE: This randomized phase II trial is studying how well selenomethionine works in treating patients undergoing surgery or internal radiation therapy for stage I or stage II prostate cancer.

The purpose of this study is to compare the effects of pomegranate polyphenol pills (POM-X) and a placebo (sugar pill) on prostatic oxidative stress. The placebo is a pill that looks like the POM-X pill but does not have an active ingredient.

RATIONALE: New diagnostic procedures, such as C-11 choline PET-CT scan, may be effective in finding cancer that has spread to the bone and lymph nodes in patients with prostate cancer. PURPOSE: This clinical trial is studying how well C-11 choline PET-CT scan works in finding metastases in patients with newly diagnosed high-risk prostate cancer.

In this study we will test a new procedure to guide needle biopsies into the prostate gland based on MRI. This study will be conducted in patients who may have recurrence of their cancer in the prostate gland after radiation therapy in order to map out the location of the recurrence. Using this technique, we will be able to measure the accuracy of MR images in identifying the site of tumour recurrence.

To evaluate the efficacy, safety and survival of two treatment regimens: Continuous Intermittent Maximum Androgen Blockade, using goserelin and bicalutamide in patients with prostate cancer. Primary endpoint is time to progression. Fifteen patients will be evaluated. QoL evaluation is also included.
