Active clinical trials for "Prostatic Neoplasms"

To explore whether the patients with prostate cancer have functional changes in specific brain areas and changes in psychological and mental characteristics compared with the patients without prostate cancer.

Androgen Deprivation Therapy (ADT) is associated with cognitive impairment and dementia in men with prostate cancer. Pre-clinical data suggest that ADT-induced hypogonadism leads to accumulation of beta-amyloid plaques in the hippocampus, a pathological hallmark of Alzheimer's Disease (AD). Neuroimaging Functional magnetic resonance imaging (fMRI) studies also demonstrate that ADT decreases metabolic activity in the parietal, occipital, and prefrontal cortices. Multiple prospective cohort and population-based clinical studies have been conducted to test the association between ADT and cognitive impairment and/or dementia. Plasma biomarkers have been developed to predict brain amyloidosis, a key pathological feature of AD and a risk factor for developing dementia due to AD. The advantage of a blood-based assay is the lower cost, invasiveness, and time compared to cerebrospinal fluid (CSF) and Positron Emission Tomography (PET)-based biomarkers.

The purpose of the study is to investigate if a new promising microRNA-based urine biomarker test for prostate cancer, called uCaP, is better than the current standard test (PSA) to identify men who would benefit from an MRI scan of the prostate. The study will include 2,500 men referred to MRI of the prostate at three major hospital centers in Denmark (Aarhus, Odense, and Herlev) and compare the accuracy of uCaP to PSA. Based on preliminary data it is expected that uCaP will be >20% better than PSA at identifying treatment-requiring cancer. Hence, uCaP could help to better pre-select men for MRI and thereby reduce unnecessary MRI scans, unnecessary prostate biopsies, as well as overdiagnosis and overtreatment of indolent PCs, while maintaining high sensitivity for aggressive PC that needs early detection and early treatment.

Background: Prostate cancer is the second leading cause of cancer-related death in American men. The disease recurs in up to 50,000 men each year after their early-stage disease was treated; however, at this stage, imaging scans are often unable to find the disease in the body. In this natural history study, researchers want to find out if a new radiotracer (18F-DCFPyL) injected before positron emission tomography (PET) imaging can help identify sites in the body with cancer. Objective: To learn more about how 18F-DCFPyL PET/CT scans detect change over time in men with recurrent prostate cancer. Eligibility: Men aged 18 and older with prostate cancer that returned after treatment. Design: Participants will be screened with blood tests. They will also have a bone scan and a computed tomography (CT) scans of the chest, abdomen, and pelvis. Participants will have an initial study visit. They will have a physical exam and blood tests. They will have a PET/CT scan with 18F-DCFPyL. The radiotracer will be injected into a vein; this will take about 20 seconds. The PET/CT scan will be done 1 to 2 hours later. Participants will lie still on a scanner table while a machine captures images of their body. The scan will take 45 minutes. Participants will return for blood tests every 3 months. Participants will return for additional scans with 18F-DCFPyL on this schedule: Once a year if their previous scan was negative for prostate cancer. Every 6 months if their previous scan was positive for prostate cancer. Participants may be in the study up to 5 years.

This protocol describes development and user testing of an educational shared decision making intervention to help men with prostate cancer who are on active surveillance make decisions with their health care providers about if and when to de-escalate surveillance testing. The project is important because for many patients their cancer does not progress to the point of needed curative treatment or their health status changes such that they are no longer good candidates for treatment. For these men, de-escalating ongoing surveillance (e.g., fewer biopsies or imaging studies) is a reasonable option.

Prostate cancer is the most common cancer in France and the 3rd most common cancer death in humans. The introduction of pre-biopsy MRI has considerably improved the quality of prostate cancer (PCa) diagnosis by increasing the detection of clinically significant PCa , and by reducing the number of unnecessary biopsies.However the diagnostic performance of Prostate MRI is highly dependent on reader experience that limits the population based delivery of high quality multiparametricMRI (mpMRI) driven PCa diagnosis. The main objective of this study is the development and the test of diagnostic accuracy of an AI algorithm for the detection of cancerous prostatic lesions from mpMRI images. The secondary objective is the development and the test of diagnostic accuracy of an AI algorithm to predict tumor aggressiveness from mpMRI images.

The purpose of this study is to see if a telemedicine group doctor's appointment is a practical (feasible) and acceptable method for following people with prostate cancer being managed with active surveillance when compared with the usual approach of individual telemedicine visits, which involve the participant visiting a doctor on their own. The researchers will compare the telemedicine group and individual visits by measuring on participant satisfaction and quality of life in each type of visit. Telemedicine is the use of secure video technology on a desktop computer, laptop, smartphone, or tablet to provide and receive healthcare from a distance.

In this study, the investigators aim to form a Brazilian national prospective active surveillance cohort of patients with low-risk prostate cancer in the public health system. The investigators aim to demonstrate data on the pathological reclassification rate, treatment-free survival, among others. This cohort aim to evaluate and validate the active surveillance strategy in Brazil.

The purpose of this study is to find out how best to detect clinically significant lesions of prostate cancer by using micro-ultrasound technology (ExactVu) and by multiparametric magnetic-resonance imaging (mpMRI).

Description: Multicentre observational study, not randomized. Ambispective character (retro and prospective). Opened to any member of the Asociación Española de Urología (AEU), public and private medicine. Justification: Active surveillance is a strategy proposed to control the overtreatment derived from the opportunist screening in prostate cancer (PCa). Its development in our country is erratic and different in every Center. This database tries to include most of patients included in active surveillance in Spain with a few minimal inclusion criteria. Multicentre registry and follow up of the active surveillance in Spain. Hypothesis: Mortality cancer specific for PCa includible in active surveillance to 15 years is lower than 5 %.
