Active clinical trials for "Prostatic Neoplasms"

Assessment of efficacy and safety of implantable spacers when used to reduce the radiation dose delivered to the organs at risk in prostate cancer patients undergoing radiotherapy.

The aim of this study is to facilitate collection of real-world data to test and train the analytics engine for each prototype algorithm. Preliminary datasets will be generated to enable a dry run of the prototype algorithms to check their predictive functionality as part of simulated 'experimental' scenarios at each LifeChamps partner site. This preparatory work will be critical to the development of the LifeChamps platform, prior to progressing to a larger scale feasibility trial.

Project Study: Pilot Human Study Specific Aims: 1. describe levels of mitochondrial respiratory enzymes 2. examine relationships between levels of mitochondrial enzymes, fatigue, and health-related quality of life; and 3. compare levels of mitochondrial enzymes in men with a clinically-significant change in fatigue from those with no change in fatigue. Significance of Study: Cancer related fatigue is a common side effect of cancer. Cancer related fatigue is poorly understood. Many different biological mechanisms have been theorized, including mitochondrial dysfunction. Self-reported descriptions of reduced energy and muscle weakness lend support for a possible relationship of cancer related fatigue to mitochondrial dysfunction. Main Research Variables: Mitochondrial Enzymes, Cancer related fatigue, and health related quality of life Design: Descriptive, longitudinal study Sample/Setting: Men with non-metastatic prostate-cancer who are scheduled to receive radiation therapy Methods: Questionnaires, mouth swabs and blood will be collected at four study visits: prior to treatment, midpoint of treatment, completion of treatment and within 90 days of finishing treatment. Four mouth swabs will be collected per participant at each study visit. Implications for Practice: Understanding the role of mitochondrial enzymes in cancer related fatigue has major clinical implications in the development of targeted interventions and in providing specific knowledge for patients and their families to make informed treatment decisions.

This observational prospective single arm cohort study is designed to assess overall survival, symptomatic skeletal event free survival and quality of life of metastatic Castration Resistant Prostate Cancer (mCRPC) patients receiving Radium- 223 under real life conditions. In addition, time to next tumor treatment (TTNT), mobility, quality of life and selfcare, independence in activities of daily living and safety will be assessed.

The purpose of this study is to better understand how cancer treatment may affect cancer cells. The research will involve genetic, molecular, cellular, and immunologic experiments using blood and tumor specimens. It is hoped that the information gained from these studies will lead to a greater understanding of castrate-resistant prostate cancer and potentially, improvements in cancer treatment. This is a tissue collection protocol requiring image-guided biopsies of metastatic, castration-resistant prostate cancer (mCRPC). The investigators will focus on enrolling patients with metastatic CRPC who have progressed while receiving novel AR-targeted therapeutics such as abiraterone and enzalutamide. This population of patients was selected because resistance develops relatively rapidly following potent inhibitors of AR activity and the mechanisms of resistance have to be better understood. Without comprehensive analysis of mCRPC tumor, the investigators will never gain a full understanding of the biology driving resistance in human disease and developing rational co-targeting approaches will not be possible.

In a participatory process involving urologists and former patients, the project team has developed an online information system ("tutorial") for patients with localized prostate cancer. In this field test, relevant outcomes are measured and the tutorial will be tested for its clinical applicability.

This pilot clinical trial studies how well acceptance and commitment therapy works in improving well-being in patients with stage III-IV cancer and their partners. Learning how to accept negative thoughts and feelings and how to live in the present without worrying about the future or past may improve coping skills in patients with stage III-IV cancer and their partners.

Broadly, the objective of this study is to evaluate the fractional decline of intensity of tracer uptake measured by SUVmax on 68Ga-PSMA PET/CT in bone metastases from prostate cancer following treatment with radium-223 as a surrogate marker for tumor cell killing.

The purpose of this study is to confirm the long term safety and efficacy of enzalutamide in patients.

This study is looking to see if a new device, diffuse optical tomography (DOT), can detect prostate cancer. The investigators will also see if DOT can tell the difference between high risk and low risk prostate cancers.
