Active clinical trials for "Prostatic Neoplasms"

This study will determine whether scanning the prostate using special magnetic resonance imaging (MRI) techniques can detect prostate cancers with greater accuracy than other methods. MRI uses a strong magnet and radio waves to produce images of body tissues. Unlike many cancers, prostate cancer is difficult to see on most imaging studies like x-rays, computed tomography (CT) scans, and conventional MRI scans. This study will use a magnet twice as strong as the magnets commonly used in MRI tests. Patients 18 years of age and older with prostate cancer confirmed by prostate biopsy may be eligible for this study. Candidates are screened with a medical history, physical examination, and review of pathology reports. Participants undergo MRI of the prostate and possibly a biopsy of the prostate gland, as follows: Prostate MRI Before coming to the NIH Clinical Center for the biopsy, patients take a Fleets enema to empty the rectum of fecal matter. For the MRI, an endorectal coil (a tube containing a specially designed antenna) is placed in the rectum, which is just behind the prostate. The coil increases the amount of signal received by the MRI unit. Additional coils may be wrapped around the pelvis to further improve the quality of the scan. The patient lies on a stretcher that moves into the scanner. A catheter (plastic tube) is placed in an arm vein for injection of a contrast agent called gadolinium, which brightens the images. Patients may also be asked to breathe an oxygen-rich gas through a mask during the scan to test the use of oxygen as a contrast agent in MRI. Patients may be asked to repeat the MRI to test the reproducibility of the procedure. The repeat test is optional. Prostate Biopsy Depending on the MRI findings, patients may be asked to undergo a prostate biopsy to obtain a sample of tumor tissue. The tissue is obtained with a needle placed through the rectum. Medicines may be used to reduce pain during the biopsy and to reduce the chance of infection.

RATIONALE: Quality of life assessment in patients undergoing prostate cancer treatment may help determine the intermediate and long-term effects of the treatment on these patients. PURPOSE: Clinical trial to study the effectiveness of two questionnaires in assessing quality of life of patients who have prostate cancer.

RATIONALE: Identification of genes that may be associated with developing certain types of cancer may someday provide important information about a person's risk of getting cancer. PURPOSE: This clinical trial is studying to see if certain genes may be associated with cancer in patients with cancer of the breast, prostate, lung, or colon and siblings of these patients.

RATIONALE: Quality of life assessment in patients undergoing prostate cancer treatment may help determine the intermediate-term and long-term effects of surgery and brachytherapy. PURPOSE: Randomized clinical trial to study quality of life in patients undergoing radical prostatectomy or brachytherapy for stage II prostate cancer.

SPECIFIC STUDY AIMS To evaluate congruence between pelvic anatomical structures segmented on MRI and/or CT scans co-registered with transperineal US scans acquired with an optically and/or electromagnetically tracked matrix array ultrasound transducer. To estimate the achievable accuracy of anatomy tracking based on 3D US matrix-array transducer imaging and grey-level based image registration algorithms.

This feasibility exploratory study objective is to assess the ability of combined MRI BOLD and 18F-MISO PET imaging to visualize tumor hypoxia compare to histological results obtained after radical prostatectomy in order to, in time, be able to identify patient with bad prognostic and to offer them the best therapeutic strategy.

This pilot clinical trial studies how well electronic patient reported outcomes work in measuring health-related quality of life in patients with stage I-IV prostate cancer undergoing treatment. Using a smartphone application to measure and monitor symptoms before, during, and after treatment may help patients better detect, understand, and manage their health.

The purpose of this study is to examine the use of MRI surveillance for patients with no prostate cancer, potential prostate cancer, or diagnosed low-grade prostate cancer.

This pilot clinical trial studies how well magnetic resonance imaging (MRI) before biopsy works in diagnosing patients with prostate cancer. MRI is a procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. This diagnostic procedure may aid in identifying lesions in the prostate which may have cancer. The lesions can then be targeted during the prostate biopsy to improve the accuracy of identifying prostate cancer.

The primary objective of this study is to collect material for study's to assess mechanisms of tumor progression, mechanisms of resistance, isolation of stem cells and biologic markers in tissue, serum and peripheral blood mononuclear cells.
