Active clinical trials for "Prostatic Neoplasms"

Prostate gland is a clinically important male sexual organ and its main function is for the production of semen. Globally, it is the second most common cancer in men globally and is also the fifth cancer cause for death in male. Despite the improvement in the understanding of prostate cancer, the current usage of serum prostate specific antigen (PSA) as a diagnostic marker is still not ideal. Many patients with elevated PSA and then subjected to prostate biopsy were found to have no prostate cancer. Therefore, there is a need to discover new biological markers to improve the current situation in diagnosis and also management of prostate cancer. From the earlier small-scale studies, urinary spermine levels have been shown to correlate well with prostate cancer diagnosis and cancer aggressiveness. Due to its nature, it could provide a more convenient and non-invasive method for detecting prostate cancer. The purpose of this study was to collect urine samples to study the role of potential new urine diagnostic markers (including Spermine and others) for prostate cancer diagnosis.

Investigators seek a new therapeutic strategy for castrated resistant prostate cancer(CRPC) patients with PI3K-AKT-mTOR signaling pathway deficiency by next generation sequencing(NGS).

This randomized phase II trial will evaluate if a low-fat diet with fish oil has the potential to delay disease progression in patients with prostate cancer undergoing active surveillance.

Identifying clinical factors such as medication, background diseases and blood tests that effect the course of disease in cancer patients can help physicians to better decide on the patient's treatment plan. The study seeks to identify and analyze relevant clinical factors that effect the course of the disease and the results of treatment in patients with cancers of the prostate, bladder and kidney.

This pilot research trial utilizes the collection of blood in studying metabolites in patients with prostate cancer. Metabolites are the small molecule products of cellular metabolism that are produced naturally in all living cells. Collecting blood in order to study metabolites may help doctors monitor and treat prostate cancer more effectively.

Background: There are several ways to treat prostate cancer. Researchers want to see how well a certain kind of imaging helps detect prostate cancer. They also want to see if a particular drug combination used before surgery will benefit people with prostate cancer that hasn't spread in the body (non-metastatic). The combination will be androgen deprivation therapy and enzalutamide. The combination of androgen deprivation therapy and enzalutamide has been shown to make patients with advanced (metastatic disease) live longer. The investigators want to see if using it earlier can increase cure rate of surgery and identify genetic or molecular characteristics that are associated with better outcomes. Objectives: - To develop better ways of detecting prostate cancer before and after pre-operative treatment. Eligibility: - Men at least 18 years old with non-metastatic prostate cancer. They must be candidates for a radical prostatectomy. Design: Participants will be screened with medical history, physical exam, and blood tests. They will have scans and X-rays. Before starting the study drugs, participants will have: Vital signs taken, medical history, and blood tests. Electrocardiogram (ECG) heart test, with patches stuck on the skin. Small piece of tumor removed (biopsy) using image guidance from magnetic resonance imaging (MRI) and ultrasound. 3T multi-parametric magnetic resonance imaging (mpMRI). Participants will lie on a table that slides into a metal cylinder. A probe will be inserted in the rectum. They will be in the scanner for about 60 minutes, lying still. The scanner makes loud knocking sounds. Participants will get earplugs. Participants will take the 2 study drugs for 6 months. Enzalutamide is taken as 4 pills once a day. Androgen deprivation therapy is given by injection 2 times over 6 months. During these 6 months, participants will visit the clinic monthly. They will have physical exam, vital signs, and blood drawn. After finishing the study drugs, participants will have another 3T mpMRI. Then they will have prostate removal surgery.

Initial performance of Ga-68-P16-093 in prostate cancer patients including dosimetry and preliminary efficacy evaluation in BCR patients, and correlation of Ga-68-P16-093 uptake with tissue histopathology in intermediate to high risk primary prostate cancer patients.

Background: Currently, patients suspected of having prostate cancer undergo ultrasound-guided systematic biopsies of the prostate. However, up to a quarter of clinically significant tumors, which may pose a risk to patient's well-being, may be missed on random biopsies. MRI enables detection of further tumors in this patient population, but also has limited accuracy. Study hypothesis: We hypothesize that hybrid PET-MRI, a novel scanner which incorporates MRI with molecular imaging will improve the detection rate of clinically significant tumors. Study design: In this prospective trial, we will recruit 57 men who are suspected of having prostate cancer but have had negative systematic biopsies, who have been diagnosed with low-risk disease but have clinically signs of more aggressive tumor or who have a focal tumor detected and are candidates for minimally-invasive tumor ablation (=tumor destruction with laser or ultrasound waves), in whom it is crucial to exclude other tumor sites. All patients will undergo PET/MRI after injection of a radiopharmaceutical called "18F-DCFPyL". This is a radioactive probe which has been shown in preliminary studies to be sensitive and specific for detection of prostate cancer. All lesions detected on PET/MRI will undergo biopsy under ultrasound using fused PET/MRI and ultrasound images for guidance, and compared to histopathology. The primary outcome measure in this study is the proportion of clinically significant prostate cancers that are detected with PET/MRI compared to MRI alone. Improved detection of clinically significant prostate cancer may enable a tailored, personalized therapeutic approach, decreasing morbidity and potentially improving overall patient outcome.

The purpose of this intervention trial is aiming to increase inform decision- making in Latino men regarding prostate cancer screening. The investigators propose to find out how much Latino men know about the benefits and risks of prostate cancer screening and what factors influence how they decide whether or not to have screening. The investigators are also interested in learning how providing education information, both verbally and in print, about the risks and benefits of prostate cancer screening affects men's interest and knowledge. The intervention is an interactive multi-media presentation made up of a small group of 8-10 Latino men gathered to discuss about prostate cancer, screening methods, treatment, and the controversy within the medical community regarding PSA screening. A facilitator guides the 1-hour discussion and encourages participant interaction. The effect of this intervention was tested on 1000 Latino men within Los Angeles county. Participants were recruited from 38 community venues (churches, community center, etc.). All participants were interviewed before being randomized to receive written (control group) or oral (intervention) prostate cancer education material. All of the participants will be followed up at 6-months via a telephone interview. The investigators hypothesize that the intervention group will have an increase knowledge of prostate cancer, will have increase communication with family, friends, and medical provider, and will have an increase rate of PSA screening compared to the control group.

Active Surveillance (A.S.) of prostate cancer (CaP) is the systematic monitoring of men with low-risk, localized lesions, with curative treatment of those whose tumors show substantial progression. A.S. is different from Watchful Waiting (W.W.), which is the palliative treatment of men with progressive prostate cancer.
