Active clinical trials for "Prostatic Neoplasms"

The purpose of this treatment protocol is to provide expanded access to MDV3100 and monitor its safety in patients with metastatic castration-resistant prostate cancer previously treated with docetaxel-based chemotherapy.

Magnetic resonance imaging (MRI) is a diagnostic study that makes pictures of organs of the body using magnetic field and radio frequency pulses that can not be felt. The purpose of this study is to determine if a new MR imaging method can help tumor evaluation in head and neck cancer or prostate cancer. The extra images will be obtained using Diffusion-weighted Magnetic Resonance Imaging which provides image contrast through detection of small restrictions in the movement of water molecules. This study may help us provide additional information about the tumor along with the picture of the organ.

Define the best analgesic method between peri prostatic blockage, analgesic suppository, oral analgesic and topic anesthetic gel, during trans rectal prostate biopsy

The objective of the study is to compare the evolution over 6 months of Health-Related Quality of Life (HRQOL) among different age groups in subjects with prostate cancer treated with GnRH agonist therapy.

This research study is being done to develop a new test to identify prostate cancer patients at highest risk of radiotherapy-related complications. This research study would allow monitoring of total tissue damage within 24 hours of radiation exposure in blood samples that could give an initial result within a few days that would help clinicians make treatment decisions. Detection of unusual tissue damage at this early time, well before symptoms occur, could allow doctors to tailor interventions that could include patient therapies that would reduce or prevent the problems that occur due to treatment of their cancer.

Data from evaluating prostate cancer (PCa) biopsy tissue from AA and white patients has led to the discovery of alternative splicing as a novel molecular mechanism underlying more aggressive PCa in AA men. Coded archival radical prostatectomy tissue specimens and annotated clinical data, questionnaire data, and ancestral genotyping data will be obtained from the racially diverse and federally funded North Carolina-Louisiana PCa Project (NC-LA PCaP). We will use 33 tissue specimens from each of the following 6 groups (n=198 total): white low aggressive, white intermediate aggressive, white high aggressive, AA low aggressive, AA intermediate aggressive and AA high aggressive. The aforementioned tissues will first be screened for tumor content and Gleason grade by a genitourinary pathologist. To identify race-related splice variants, RNA will be isolated for targeted sequencing of prioritized race-related alternatively spliced genes using the NimbleGen SeqCap Target Enrichment, SeqCap RNA System to capture regions of interest and the Illumina HiSeq sequencing platform to sequence these regions at a depth and coverage sufficient to accurately call alternative splicing events.

68Ga-PSMA is a radiopharmaceutical used with PET imaging for the detection of prostate cancer under a compassionate IND in patients who have presented with biochemical failure. In this study, the use of 68Ga-PSMA-11 will be extended to newly diagnosed patients with high risk prostate cancer. Patients enrolled to this study will undergo a 68Ga-PSMA-11 PET/CT or PET/MRI scan for research purposes (in addition to the routine CT or MRI that is routinely done for staging), and a second 68Ga-PSMA-11 administration just prior to surgery for experimental ex-vivo beta probe testing of resected tissue. Immediately following resection of the prostate, the intact tissue will be scanned using a PET camera designed for animal research in order to record the 68Ga-PSMA-11 distribution in the isolated tissue at higher resolution than can be attained using whole-body PET imaging. The experimental beta probe will then be use to measure 68Ga-PSMA-11 counts of the resected tissue.

Phase A: To describe and to determine the maximum standardised uptake values (SUV) in prostate specific membrane antigen positron emission tomography (PSMA-PET) before ADT and 7, 14 and 28 days after ADT. Phase B: To validate phase A results by comparing the PSMA-PET findings to histopathological analysis of regional lymph nodes acquired from radical prostatectomy specimens. PSMA-PET is done before ADT and at maximum SUV defined by the phase A.

The purpose of the study, is to determine the percentage of patients for whom the initial LHRH prescription has been renewed

Patients with know prostate cancer (PCa) under active surveillance and aged matched controls without evidence of PCa will have a PSA blood test prior to and following standardized digital rectal examination
