Comparison of Multiparametric Prostate MRI and Ga-68 PSMA PET Imaging in Prostate Cancer Staging...
Prostate CancerProstate Cancer StageIn this study, it is aimed to compare the lesion location, lesion size, local and distant metastases detection rates of Ga68 PSMA PET and Multiparametric Prostate MR imaging tests used in staging in patients diagnosed with prostate cancer. The pathologies of the patients who were decided to undergo radical prostatectomy as a treatment will also be compared with the staging tests.
PSMA-PET to Guide Prostatectomy
Prostate CancerIn this study, 288 patients will be randomized 1:1 to either having only the standard of care MRI prior to surgery versus having the standard of care MRI and the PSMA PET scan. PET (and MRI) findings will be validated against whole mount pathology. Pre-surgical imaging findings will also be evaluated in the context of affecting subsequent surgical plans and impacting actual patient outcomes.
The Application Research of Ultrasound Guided Puncture Stent Assisted Transperineal Prostate Biopsy...
Prostate CancerThis study is a multi-center prospective study. Patients who meet the indications for prostate biopsy were included in this study.The study was randomly divided into two groups, one group was transperineal free-hand biopsy; the other group was puncture stent-assisted transperineal prostate biopsy. Exploring the positive rate of puncture stent-assisted transperineal prostate biopsy
Comparative Study of Diagnostic and Prognosis Biomarkers of Prostate Cancer in Liquid Biopsy
Prostate CancerHealthy DonorsConstitution of a biological collection within the framework of the establishment of a diagnostic, prognostic and active surveillance test for prostate cancer from long non-coding RNA biomarkers, in 3 cohorts of patients, with cancer of the prostate, with suspected cancer without biopsy confirmation or with prostatic hyperplasia and healthy donors. This biological collection will also be used as a support for further researches on the identification of biomarkers and genetic markers to improve the prognosis and diagnostic management of patients with prostate pathologies.
Improving Quality of Life After Prostate Brachytherapy: a Comparison of HDR and LDR Brachytherapy...
Prostate CancerOptimal non surgical treatment of prostate cancer requires dose escalation which is frequently provided by adding a brachytherapy "boost" to a short course of external beam radiotherapy. The hypothesis in this randomized study is that a High Dose Rate (HDR) brachytherapy boost leads to equivalent or better Prostate Specific Antigen (PSA) recurrence-free survival when compared to a Low Dose Rate (LDR) brachytherapy boost and that it is associated with a more favorable toxicity profile and improved quality of life.
Prostate Cancer Screening With Abbreviated MRI Protocol
Prostate CancerProstate cancer is one of the most common malignancies in the male population with incidence and mortality rates comparable to breast cancer in women, but in contrast, a population screening program that would fulfill all the recommended criteria is not yet available. According to international recommendations, the preventive PSA sampling used in clinical practice is not suitable because of the concurrent detection of clinically insignificant carcinomas in a major proportion of tests. These clinically non-significant cancers make up a significant and increasing proportion with age. Detection of non-significant cancers burdens the health care system and patients with the care that has no positive impact on their health. Current preventive serum prostate-specific antigen (PSA) testing does not distinguish benign hyperplasia and nonsignificant carcinoma from clinically significant cancer. It is therefore not suitable for full-scale screening. According to current guidelines, magnetic resonance imaging (MRI) is indicated only in patients with an increased risk of cancer for detection or staging after biopsy and is not used for screening. According to recent studies, MRI has detected an increased proportion of significant cancers in the general population compared to screening based on PSA, while fewer clinically insignificant cancers have been detected. In screening, a shorter examination protocol without contrast medium (biparametric MRI) is used with a lower cost per examination, allowing to increase both the number of patients examined and patient comfort. The main objective of the project is to assess the contribution of imaging in the screening of clinically significant prostate cancer and to validate the published results in the Czech population, and extend the screening model by the second round of examinations and additional laboratory markers. The secondary aim is to design a subsequent study with a larger number of participants allowing statistical evaluation, similar to the successful breast cancer screening.
Imaging and Genomic Biomarkers to Predict Response in Prostate Cancer
Prostate CancerThe purpose of this study is to evaluate the imaging and gene expression biomarkers in prostate cancer. Participants have high-risk prostate cancer and have indicated they will undergo external beam radiation therapy, brachytherapy, and androgen deprivation therapy (EBRT+BTX+ADT). Participants can expect to be in this study for up to 5 years.
Transperineal, MRI-guided, Prostate Biopsy
Prostate CancerPrimary purpose: Complications and rehospitalizations after transperineal prostate biopsy MRI-guided are reduced than transrectal prostate biopsies. Secondary purposes: Patients tolerance after transperineal prostate biopsy MRI-guided is better than after transrectal prostate biopsies. Core of transperineal prostate biopsies are better than core of transrectal prostate biopsies Study of correlation between radiologic images and anatomopathologic result Description of needle track during the procedure Description of real time template saturation prostate biopsy Comparison of transperineal prostate biopsy relevance according to EBM Comparison of 1.5T MRI and 3T MRI for prostate cancer detection
Neoadjuvant Phase 2 Study Comparing the Effects of AR Inhibition With/Without SRC or MEK Inhibition...
Prostate CancerProstate cancer is the most common cancer in men and the second leading cause of cancer death in men. The purpose of this research study is to compare prostate cancers treated with hormone therapy versus prostate cancers treated with hormone therapy plus drugs that directly target cancer cells.
Using Virtual Reality (VR) Models for Robotic Prostatectomy - UNC
Prostate CancerA prospective, randomized, controlled study designed to assess whether digital virtual reality (VR) models, created from existing CT scans and MRIs, provide surgeons with an improved understanding of their patients' anatomy, resulting in more efficient operations (robotic prostatectomy) and improved patient care.
