Blood Test to Measure DNA Damage in Blood
Prostate CancerTo check the radiosensitivity level in individual patients based on their DNA damage level.
Imaging of Prostate Cancer Using Two-dimensional MR Spectroscopy and Diffusion Tensor Imaging
Prostate LesionsThe goal is to develop MR imaging techniques to improve delineation of cancer extent, and to improve differential diagnosis between prostate cancer and benign prostate hyperplasia or other benign diseases.
Active Control of Prostatic Cancer With Criteria of Latence
Prostate CancerThis study concern a prospective cohort pf patients with latent prostate cancer. We study the specific survival at 10 years of patients who accept an active control.Patients inclusion are realized in 2 stages: patient with inclusion criteria (PSA < 10 ng/ml, clinical stage T1c or T2a, Gleason < or = 6) are registered if they accept a second prostate biopsy in a 3 months delay after analyse of second biopsy in central laboratory and confirmation of latent prostate biopsy, patients are included if they accept active control Included patients will have 1 biopsy by years the first two years and then 1 biopsy each 2 years during 8 years. If progression of cancer happens during the 10 years control, active control will be stopped and patient will be treated by surgery and chemotherapy.
ExoDx Prostate Evaluation in Prior Negative Prostate Biopsy Setting
Prostate CancerThe study is designed to confirm the performance of the ExoDx Prostate test in prior negative biopsy patients now presenting for a repeat prostate biopsy. Note: ExoDx Prostate test results are collected for correlation to biopsy results and are not disclosed to the physician or study subject.
Registry to Measure the Impact of Adding Genomic Testing
Prostate CancerThis is a prospective open registry to measure the impact on first-line therapy of genomic testing of biopsy tissue from recently diagnosed treatment-naïve patients with early stage localized prostate cancer. Physicians will complete a series of questionnaires. Biopsy tissue will be tested using the Prolaris® genomic test and a relative cancer aggressiveness score will be shared with the physician and the patient.
Molecular Characterization of CTCs and ctDNA in Blood and Plasma Samples From Patients With Metastatic...
Hormone-Resistant Prostate CancerMetastatic Prostate CarcinomaThis research trial studies molecular characterization of circulating tumor cells (CTCs) and circulating tumor (ct) deoxyribonucleic acid (DNA) in blood and plasma samples from patients with prostate cancer that has spread to other places in the body and/or has not responded to previous treatment with hormones. Studying samples of blood and plasma collected from patients with prostate cancer before, during, and/or after treatment in the laboratory may help doctors learn more about changes that occur in DNA and identify the development of drug resistance.
Transrectal Photoacoustic Imaging of the Prostate
Prostate CancerThe purpose of this study is to image human prostate tissue using a new transrectal photoacoustic imaging probe and correlate this with ultrasound and MRI imaging performed once the specimen has been surgically removed. We hope to see what we can visualize with our device as this has never been done before. Eventually, we hope to use a similar device to image the prostate in men being seen by their doctor for prostate cancer.
Anatomical and Functional Differences Between Continent and Incontinent Men Post Radical Prostatectomy...
Prostate CancerPost Prostatectomy IncontinenceOne out of every six men will be diagnosed with prostate cancer and post prostatectomy up to 75% report urinary incontinence. There are many hypotheses about the exact cause of post prostatectomy stress incontinence (PPI). Existing studies have focused on surgical or cadaveric dissections to define structures responsible for PPI. Contemporary 3T MRI now allows three dimensional, sub-millimeter resolution of the human pelvis and clearly demonstrates pelvic anatomy without the distortion of dissection. It is our overarching hypothesis that PPI is multifactorial and occurs because of a combination of specific anatomical and functional impairments. We propose conducting a case control study with matching for age and race to compare the MRI anatomy and urinary tract function on urodynamics between 20 men with PPI (cases) and 20 men who are continent post prostatectomy (controls) who are all a minimum of 12 months post surgery. We will use static and dynamic MRI at 3 Tesla to make objective measurements of the bladder neck, external urethral sphincter, pelvic floor, urethral anastomotic fibrosis, and urethral hypermobility- all believed to play a large part in continence. Multi-channel urodynamic studies will also be performed to assess the leak point and maximum urethral closure pressure. All cases and controls will complete standardized questionnaires - the AUA symptom index and the Incontinence Severity Index as a quality of life measure. This study is needed to provide critical information about causes of male PPI, a quality of life altering voiding dysfunction, and will assist with the advancement of pharmacological and surgical treatment of this disease.
Soft Tissue Detection on MRI, Cone Beam CT and Fan Beam CT and Integration of Functional MRI
Lung CancerProstate CancerThis clinical trial studies magnetic resonance imaging (MRI), cone beam computed tomography (CT), and fan beam CT in detecting soft tissue in patients with prostate and lung cancer undergoing radiation therapy. Comparing results of diagnostic procedures done before and during radiation therapy may help doctors predict a patient's response to treatment and help plan the best treatment.
Post-marketing Surveillance Regarding Efficacy and Safety of SpaceOAR™
Prostate Cancer Patients Treated by RadiotherapyA treatment with SpaceOAR™ hydrogel does reduce late toxicity Grad 2 and Grad 3 of radiation therapy in prostate cancer patients
