Active clinical trials for "Prostatic Neoplasms"

The purpose of this study is to evaluate the prevalence of 4 or more DNA-repair gene defects in a population of men with metastatic Prostate Cancer (PC) and to use the reported DNA-repair gene defects to assess biomarker eligibility for niraparib interventional studies.

The prostate gland is a clinically important male accessory sex gland and vital for its production of semen. Prostate cancer (PCa) is now ranked 3th in annual incidence of male cancer and ranked 5th for cancer-related death in men in Hong Kong which accounts for about 10.9 deaths per 100,000 persons. Its incidence is rising rapidly, almost tripled in the past 10 years. Fortunately, with the improvement in awareness of the disease and also increasing use of serum prostate specific antigen for early case identification, many patients are diagnosed at an earlier stage. However, unlike other malignancy, PCa is characterized by its slow progression nature. Therefore, some patients with low grade low volume disease might never suffered from PCa related complications or mortality. As a result, recent year, there is an increase use a more conservative approach, active surveillance (AS), for management of early prostate cancer. The principle of AS is selecting patients with low risk of disease and offered them regular monitoring, instead of radical local therapy, unless patient's cancer was noticed to progressing. By using this approach, patients might avoid possible complications related to treatment. Currently, people could use some clinical parameters, imaging and repeated prostate biopsy to assess and monitor the aggressiveness/ progression of PCa. However, these parameters suffered from defects, such as low correlation to the final PCa pathology or not readily repeatable for patients. Therefore, there is a need to identify more easy, safe and repeatable monitoring of the aggressiveness of prostate cancer. Exosome is genetic materials secreted by cells and could be measured in various body fluid. There are some studies suggested it is a potential marker for PCa diagnosis and monitoring. The aim of this study is to investigate the relationship of urinary exosome and the aggressiveness of prostate cancer.

The purpose of this study is to determine whether adding new methods of data visualization to routine clinical care will improve (i) surgical planning and (ii) surgical outcomes in patients with kidney and prostate tumors.

• Correlation of a glycoprotein panel with prostate biopsy outcome and PCa aggressiveness

PROREPAIR is a prospective multicenter observational cohort study of unselected patients with metastatic Castration Resistant Prostate Cancer (mCRPC) with unknown germline mutational status at study entry and who are candidates to start 1st line treatment with any approved survival-prolonging agent. The study aims to evaluate the impact of aberrations in DNA-repair genes,(BRCA1, BRCA2, ATM and PALB2 and other genes) on cause-specific survival from the diagnosis of the metastatic castration resistant status and other outcomes.

Prostate biopsies are the gold standard for prostate cancer (PCa) diagnosis. They are performed according to the results of the measurement of prostate-specific antigen (PSA) in the serum of patients with PCa suspicion. More than half of the prostate biopsies reveal eventually negative because of the poor specificity of prostate-specific antigen assay. The Prostate Health Index (PHI) is a new diagnostic tool that has been described as a good predictor of prostate biopsy outcome. No large study has been performed so far in France. This study aim to evaluate Prostate Health Index diagnostic performances in a large multicentric French cohort of patients undergoing prostate biopsies because of clinical and/or biological suspicion of prostate cancer. Prostate Health Index will be measured in patients directed to prostate biopsies according to usual practices. Inclusion of 400 patients within 6 months in 12 French centers is expected. The ability of Prostate Health Index to predict prostate cancer at biopsy will be evaluated in terms of intrinsic and extrinsic diagnostic performances including sensitivity, specificity, predictive values, diagnostic accuracy, area under receiver operating curves and decision curve analyses.

This is a three-year project funded by a Cancer Research UK Multidisciplinary Award and brings together a team from UCL Division of Medicine, Computer Science and University College London Hospital. The aim is to develop Magnetic Resonance (MR) sequences and mathematical algorithms to reduce the distortions in MR images, especially of the prostate.

The aim of the study is collecting clinical data on the learning curve of different surgeons using the EinsteinVision® 3D visualization system in laparoscopic radical prostatectomies.

Several studies have shown a great potential of 68Ga-PSMA PET in high risk prostate cancers patients and a high detection rate than 18F-Choline PET. The primary aim of this study is to evaluate the difference of management intent, after the inital staging of high risk prostate cancer patients, with 68Ga-PSMA-11 PET-CT results in comparison of 18F-Choline PET-CT results.

The North Carolina-Louisiana Prostate Cancer Project is a population-based case-only study of over 2,000 men newly diagnosed with prostate cancer designed to address racial differences in prostate cancer aggressiveness and survival through a comprehensive evaluation of social, individual, and tumor level influences on prostate cancer aggressiveness. Project 3 specifically aims to examine nutritional modulation of prostate cancer aggressiveness using dietary assessment and biomarker-based data on dietary factors.
