Active clinical trials for "Prostatic Neoplasms"

Prostate cancer is the most common cancer in men over 50 years old and the third leading cause of cancer death. Because of the variety of prostate cancers, different treatments exist. Several criteria guide this management in daily practice: PSA level; TNM stage (digital rectal examination, trans-rectal ultrasound and classical visual imaging) and pathological differentiation with the Gleason score, to which can be added other prognostic criteria: growth and doubling time of the serum PSA, number of positive biopsies and percentage of cancer lesions by biopsy. Functional imaging by PET and MRI is increasingly used in daily clinical practice to characterize prostate cancer, either during initial discovery or during recurrence. In this context, it is the qualitative visual analysis that is mainly used. Quantitative image analysis could add new criteria to guide patient management. Consequently, the objective of this study were: Optimization of 18F-choline PET/CT Acquisition in Prostate Cancer Comparison the quantitative parameters obtained by 18F-Choline PET / CT and both perfusion MRI and histological parameters.

The purpose of this study is to document the course of advanced prostate cancer in Canada in terms of disease progression, real-world treatment, and patient management.

This study aims to learn how to improve MRIs (Magnetic Resonance Imaging) that do not require the patient to be injected with a contrast dye. Researchers expect to learn how to better find and describe tumors in patients with prostate cancer. Participants have a whole body research MRI scan within 90 days of a standard-of-care imaging procedure. The research study will collect copies of those scans to compare to the research scans as part of the study analysis. Patients who have additional standard-of-care scans within 12 months after their research scan may be asked to have a second non-contrast MRI for research within 90 days of their follow-up standard of care imaging. The whole body MRI scan will be compared to the standard-of-care scan for prostate cancer detection and to assess patient response to standard-of-care treatment.

The overall goal of this pilot project is to test the hypothesis that a decline in muscle strength precedes the decline in bone strength in men undergoing androgen deprivation therapy (ADT) for prostate cancer. The investigators will measure changes in serum biomarkers involved in muscle-bone crosstalk, anatomic changes in muscle and bone structure and strength that could ultimately contribute to fractures. The findings from this research will inform design of interventions to reduce falls and hip fractures in patients undergoing ADT as well as application to broader populations of at risk patients.

This is a prospective observational study to evaluate effectiveness and safety of Enzalutamide for Castration Resistant Prostate Cancer (CRPC) patients who decided to administer Enzalutamide after anti-androgen therapy. CRPC Patients who are observed PSA or disease progression after anti-androgen therapy and decided to administrate Enzalutamide will dose the Enzalutamide 160 mg orally once daily and observed the practical treatment. Total research term is for 4 years, consists of 2-year case registration terms and 2-year observational terms.

The purpose of this study is to temporally evaluate the impact of abiraterone acetate (ZYTIGA) therapy on Patient Reported Outcomes (PROs) and on clinical outcomes in the chemotherapy-naive metastatic castrate-resistant prostate cancer (mCRPC) population. Safety data, levels of health care resource utilization associated with abiraterone acetate (ZYTIGA) therapy will also be prospectively collected and analyzed.

Radiotherapy (RT) is an important treatment for prostate cancer with over 10,000 men receiving RT per year in the UK. Prostate RT aims to deliver radiation dose to the prostate to kill cancer cells whilst minimizing the dose given to surrounding normal tissues, such as the bladder or the rectum. Radiation is delivered in a number of daily treatments which are called 'fractions'. The position of the prostate varies each day and during the radiation delivery. To accurately aim the radiation the prostate needs to be located before daily treatment. Clarity is an ultrasound image guidance system that locates the prostate and monitors its position during treatment. Ultrasound does not give a radiation dose, is non-invasive, provides fast imaging and can easily visualise soft tissues. Before Clarity is implemented the investigators wish to ensure that it can accurately locate and monitor the prostate by comparing Clarity with marker-based techniques in 24 patients. Patients receive markers as part of other trials which are currently recruiting at The Royal Marsden (for example, patients in the DELINEATE trial and the PACE trials receive implanted gold markers and patients in the PROSPARE trial have received electromagnetic markers). Patients who have received or will be receiving markers as part of other studies will be asked to also to take part in this study. This means that there will be no additional intervention for patients as a result of this study. Clarity will be considered a safe and effective imaging system if the mean and standard deviation of the differences between Clarity measurements and marker measurements, of prostate position, are less than 1mm. It is possible that markers will influence the Clarity measurements. To find out if this happens, the mean and standard deviation of Clarity measurements in a group of 24 patients without markers to the group with markers will be compared. Primary Aim: To evaluate the accuracy of Clarity ultrasound image guidance system for prostate motion estimation during treatment (intra-fraction), by comparison with implanted marker-based image guidance techniques. Primary Hypothesis: Clarity can be safely used to deliver radiotherapy using similar (within 1mm) treatment margins to those that would be employed if fiducial markers based image guidance techniques were used.

This retrospective observational multi centered study has been established to collect the clinical experience relating to the administration of Fluciclovine 18F employed in both investigator initiated studies and named patient/compassionate use programmes in up to 5 sites.

This is a prospective evaluation to determine the effectiveness of the Prostate Cancer Supportive Care (PCSC) Program's group therapy program, Living with Prostate Cancer (LPC). LPC is an intervention which utilizes a small group format (5-7 participants with 2 leaders and a paraprofessional counselling student) to understand and learn how to manage emotional responses, depressive symptoms, and life stressors associated with prostate cancer. Data for this evaluation will be derived from a focus group (at 3 months) and self-report questionnaires that participants will complete immediately prior to the intervention, immediately following the intervention and at 3, 6, and 12-months post-intervention.

The project aims at developing and structuring a network of clinicians, pathologists, and scientists, from the "Grand Ouest" area, most of them already involved in prostate cancer management and research. Patients treated by radical prostatectomy will be recruited within the ReSCaP network of clinicians, with centralized database and standardized bio-resource collection, including prostate and adipose tissue samples. Seven clinical centers will participate to the network, 6 recruiting mainly Caucasian patients, and 1 from the French West Indies recruiting mainly African Caribbean patients. After 18 months, 1000 patients will be included. The main goal is to study the relationships between adipose tissue/lipids and prostate cancer aggressiveness. In fact, adipose tissue is likely to be involved in cancer progression at many levels: abdominal obesity has been associated with aggressive disease, and poly-unsaturated fatty acids (PUFAs), as well as cytokines produced by adipocytes (adipokines) have an impact on cancer cells growth and migration in vitro. Moreover, adipose tissue is the preferential site of storage of persistent organic pollutants with estrogenic properties, which could impact cancer progression. The study will analyze the association between adipose tissue (distant from the prostate) composition and cancer aggressiveness. Among the 1000 patients, 100 aggressive tumors will be selected according to the d'Amico criteria (Gleason score 8 or more and/or pT3 tumors). They will be matched with 100 potentially indolent prostate cancers (Gleason 6 or less, and PSA less than 10, and pT2 stage on the surgical specimen). These 200 adipose tissue samples will be analyzed for 1/ the lipid profile, including the fatty acid composition, particularly PUFAs, that reflects past dietary fat intake, 2/ adipokine expression, and 3/ tissue concentrations of persistent organic pollutants belonging to the class of organochlorine pesticides with hormone-like activity.
