Apalutamide in Treating Patients With Prostate Cancer Before Radical Prostatectomy

This phase II trial studies how well apalutamide works in treating patients with prostate cancer before radical prostatectomy. Androgen can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by lowering the amount of androgen the body makes and may make it less likely for patients to receive radiation therapy after surgery.

Germline DNA-Based Radiosensitivity Biomarker Influence on Toxicity Following Prostate Radiotherapy, GARUDA Trial

This trial studies the changes in long-term physician-scored genitourinary toxicity achieved in prostate cancer patients eligible for stereotactic radiation therapy when both patients and physicians have access to convincing but non-validated germline signature that can characterize patients as having a low or high risk of developing toxicity after radiation therapy. The information learned from this study may guide patients' and physicians' decisions on radiotherapy fractionation.

Effects of Relugolix vs Leuprolide on Cardiac Function in Patients With Prostate Cancer

This phase II trial compares the effect of relugolix to leuprolide on cardiac function and performance in patients with prostate cancer. Androgen deprivation therapy (ADT) has been a key component for the treatment of advanced prostate cancer for decades. The term androgen deprivation therapy means lowering a man's testosterone. Long-term studies show that ADT may contribute to a detriment to cardiac health and predisposes men to developing cardiac diseases. Recent studies suggest that men taking relugolix for treatment of prostate cancer may have a lower risk of developing cardiovascular problems, but more studies are needed to understand this observation, and there are currently no studies reporting the direct impact of ADT (relugolix, versus the more-commonly used leuprolide) on cardiac function and outcomes. Participants will receive definitive radiotherapy for unfavorable intermediate risk prostate cancer and 6-month ADT (either relugolix or leuprolide). In addition, participants will undergo the following: 1. Comprehensive cardiac and exercise testing before and after starting ADT 2. Completion of quality-of-life questionnaires at specific intervals during the study period 3. Provide blood samples at specific intervals during the study period to test for changes in steroid levels and certain biomarkers

RElugolix VErsus LeUprolide Cardiac Trial

This clinical trial investigates the impact of prostate cancer treatment, specifically androgen deprivation therapy (ADT), on the heart and coronary vessels among men with localized, non-metastatic prostate cancer undergoing definitive radiation therapy and concomitant ADT. Recently, cardiovascular toxicity from hormone therapy that is routinely used for prostate cancer (e.g. leuprolide) has emerged as a concern, yet studies identifying who is at risk and the mechanism of cardiac damage are lacking. Additionally, a new hormone therapy drug, relugolix, has recently been Food and Drug Administration (FDA)-approved and may reduce toxicity to the heart. This trial intends to investigate the mechanism of cardiovascular toxicity from ADT, investigate the mechanism by which relugolix reduces cardiovascular toxicity, and identify predictive biomarkers to improve individualized risk-assessment for cardiovascular toxicity from ADT.

SBRT Versus Hypofractionated Radiotherapy for Biochemically Recurrent or Oligometastatic Prostate Adenocarcinoma

This phase III trial tests the side effects of stereotactic body radiation therapy (SBRT) compared to hypofractionated radiotherapy for treating patients with prostate adenocarcinoma that has come back after a period of improvement (recurrent) or that has spread from where it first started (primary site) to a limited number of sites (oligometastatic). SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumors cells and have fewer side effects. SBRT may work just as well as hypofractionated radiation therapy at treating patients with biochemically recurrent or oligometastatic prostate cancer, but with a shorter treatment time and possibly fewer side effects.

Lifestyle Behavior Influences Among African American Patients With Stage 0-III Prostate Cancer Survivors and Their Partners

This trial studies the day-to-day stress, social support, and health lifestyle behaviors (such as physical activity and nutrition) in African American patients with stage 0-III prostate cancer survivors and their partners. How patients cope with stress may affect their lifestyle behaviors. This study may help understand not only survivors' behaviors but also partners' behaviors and how they interact.

White Button Mushroom Sup for the Reduction of PSA in Pts With Biochemically Rec or Therapy Naive Fav Risk Prostate CA

This phase II trial studies how well white button mushroom supplement works in reducing prostate-specific antigen (PSA) levels in patients with prostate cancer that has come back (recurrent) or has favorable risk and has not undergone any therapy (therapy naive). PSA is a blood marker of prostate growth. White button mushroom supplement may affect PSA level, various parameters of immune system and levels of hormones that may have a role in prostate cancer growth.

Comparison of High-Dose Rate Brachytherapy and Stereotactic Ablative Radiotherapy as Monotherapy for the Treatment of Localized Prostate Cancer

This phase II trial compares high-dose rate brachytherapy and stereotactic ablative radiotherapy as monotherapy in treating patients with prostate cancer that has not spread to other parts of the body (localized). High-dose rate brachytherapy delivers radiation directly into the prostate within a few minutes by a single radioactive seed through temporarily placed plastic catheters inside the prostate gland. Stereotactic ablative radiotherapy is an external beam radiation method that delivers large doses of radiation to the cancer in a short period of time, usually 5 treatments. This trial aims to find which of these two approaches is better in terms of patient-reported quality of life.

Aspirin and Rintatolimod With or Without Interferon-alpha 2b in Treating Patients With Prostate Cancer Before Surgery

This phase II trial studies how well enteric-coated (EC) aspirin and rintatolimod with or without interferon-alpha 2b work in treating patients with prostate cancer before surgery. EC Aspirin may help to keep the prostate cancer from coming back. Rintatolimod may stimulate the immune system and interfere with the ability of tumor cells to grow and spread. Interferon-alpha 2b may improve the body's natural response to infections and may slow tumor growth. It is not yet known how well rintatolimod, EC aspirin, and interferon-alpha 2b work in treating patients with prostate cancer undergoing surgery.

rhPSMA-73 PET-MRI Imaging for the Detection of Prostate Cancer Among Men Who Are Otherwise Candidates for Active Surveillance

This clinical trial evaluates whether positron emission tomography-magnetic resonance imaging (PET-MRI) using the radioactive drug radiohybrid prostate-specific membrane antigen (rhPSMA)-7.3 may help in detecting higher grade or stage disease in men with low and favorable intermediate risk prostate cancer who are candidates for active surveillance. A PET scan is a test that uses a radioactive drug and a computer to create images of how organs and tissues in the body are functioning. The radioactive drug used in this study, rhPSMA-7.3, attaches to the abnormal cells in the body at a different rate than normal cells which allows the scanner to create a detailed picture of how the body is working. An MRI scan uses strong magnets and computers to create detailed images of the soft tissue in your body. A multiparametric (mp)MRI is a type of MRI scan that creates a more detailed picture of the prostate gland. Using rhPSMA-73 with PET-MRI and mpMRI may be more effective in detecting higher grade or stage disease in men with low and favorable intermediate risk prostate cancer.
