This study is trying to find out if the combination of Androgen deprivation therapy (ADT), MRI guided high dose radiation (HDR) brachytherapy treatment (internal radiation implant procedure) and external beam radiation therapy (EBRT) treatments lead to less side effects. This study is also looking at patient outcomes, quality of life, and overall survival for patients receiving this treatment. Read Less

This study will collect blood from patients with cancer to study the level of cells which decrease the immune response (suppressor cells) before and after chemotherapy. Patients 18 years of age and older with cancer may participate. This study does not involve treatment. Participants will have about 50 ml (3 tablespoonfuls) of blood drawn. Depending on their condition, patients may be invited to enroll in a clinical research study involving chemotherapy, radiotherapy, or surgery. Additional 40-ml blood samples may be drawn during the course of treatment. ... Read Less

Background: The current standard treatment of prostate cancer is either surgery or radiation. Typically, this includes either the removal or radiation of the whole prostate gland. Many people now seek out focal therapy options to decrease the side effects of treatment. Until now, several forms of physical destruction with heat (thermal ablation), cold (cryotherapy), sound waves (HIFU), laser (FLA), and electrical energy (IRE). A new type of radiation (SBRT) may be an effective way to cure men of early-stage prostate cancer with fewer side effects than standard treatments. Objective: To see how people with untreated localized prostate cancer will respond to focal therapy with SBRT. Eligibility: People aged 18 years and older with untreated localized prostate cancer (prostate cancer which has not spread outside of the prostate gland). Design: * Participants will undergo screening including blood tests, an MRI, a PSMA PET/CT (18F-DCFPyL), and a biopsy. * Small, non-radioactive, gold seeds about the size of a grain of rice will be placed in and/or around the tumor to help target the radiation treatment. * Radiation (SBRT) will occur in 2 separate sessions about 1 week apart. No sedation is used, these sessions are painless. Each session will take about 1-2 hours. Participants can go home afterwards. * Follow-up will continue for 2 years with repeat scans (MRI and PSMA PET/CT) and blood (PSA) tests. * After two years, a biopsy will be done to understand the impact of this new treatment on prostate cancer.

This study aims to provide long-term follow-up care of patients previously enrolled in a vaccine study that involved poxviral vectors. Vectors are sequences of genetic material that can be used to introduce specific genes into genetic makeup. The study does not involve the use of any drug or biologic agent. Participants will undergo an annual health history. Because certain viruses enter into cells and create proteins from the viral genes, the type of vaccine treatment used is referred to gene therapy. The genes expressed by poxviral vectors do not become part of the genetic material left behind. Because gene therapy is a somewhat new technology, a prolonged monitoring of patients' health status is necessary, according to new specific reporting requirements for harmful events in patients who undergo such gene therapy studies. The risk of any long-term negative effects from the gene therapy that patients had received is quite small. Still, it is important that there be updates at least annually. This annual monitoring of health status will extend for 15 years, according to guidelines from the Food and Drug Administration, or for as long as patients are willing to participate. Patients who received poxviral vectors (vaccinia or fowlpox, or both) at the National Cancer Institute, through a trial affiliated with the Laboratory of Tumor Immunology and Biology, may be eligible for this study. Participants will be involved in the following forms of data collection: * Annual medical history and physical examinations for the first 5 years following the last vaccine. * Annual telephone contact during the last 10 years. * Health status check, including primary cancer status, secondary malignancies, neurologic disorders, autoimmune disorders, and hematologic disorders. * Blood tests for the presence of HIV antibodies. * Reporting of medical problems, including information on unexpected hospitalizations and medications. If a participant has died, the study will document the cause of death and autopsy information if available. ... Read Less

Background: Prostate cancer is the most common noncutaneous cancer among men in the U.S. Researchers want to study blood, tissue, and fluid samples of people with prostate cancer. This will help them understand any changes in cells and genes. These changes might lead to the development and progression of prostate cancer. Researchers think the study could lead to new treatments. Objective: To understand the changes in cells and genes that lead to the development and progression of prostate cancer. This could lead to new treatments. Eligibility: Men ages 18 and older who have or are suspected to have prostate cancer Design: Participants will be screened with physical exam and medical history. Participants will send tissue blocks of their tumor, if possible. If not, they will provide unstained slides of tumor tissue. Participants may provide samples of blood, urine, saliva, and prostate secretions. Participants may have imaging tests. They will lie in a machine that takes pictures of their body. These tests include: MRI of the prostate CT of the abdomen and pelvis Chest x-ray Participants may need a biopsy or surgery for treatment of their cancer. If so, researchers will collect tissue. Participants may answer questions about their prostate cancer and quality of life. Participants may have follow-up visits or other treatments. They may have follow-up phone calls every few months. ... Read Less

This study will enroll prostate cancer patients with an unfavorable intermediate- or high-risk diagnosis. The purpose of this study is to determine whether a regimen of pembrolizumab and low dose prostate radiation or low dose prostate radiation alone prior to a prostatectomy affects cells of the immune system and if it is a safe option for this stage of prostate cancer. Participants will be randomized 1:1 (like flipping a coin) to receive pembrolizumab, low dose prostate radiation and a prostatectomy or low dose prostate radiation and a prostatectomy. Pembrolizumab is an investigational drug that increases the ability of the immune system to kill tumor cells. Low dose radiation can alter the way tumor cells look to the immune cells. For example, the immune cells may express different proteins that make them more susceptible to immune cell killing or the structure of the tumor may be altered to allow the immune cells to infiltrate the tumor more thoroughly. The prostate tissue collected from the prostatectomy will be analyzed for differences in pathology and local immune cell infiltration, and participants will be followed for 2 years to watch for prostate specific antigen (PSA) recurrence and prostate cancer recurrence.

Background: Active surveillance (AS) is a standard approach to treat low and intermediate risk prostate cancer. For AS, disease progression is monitored. AS uses biopsies, prostate specific antigen (PSA) blood tests, and other tools. Researchers want to see if multiparametric magnetic resonance imaging (mpMRI) can help improve AS. Objective: To see if mpMRI can improve how people are monitored during AS. Eligibility: Men age 18 and older who have been diagnosed with prostate cancer within the last 2 years. Design: Participants will undergo AS. Their PSA level will be checked once a year via blood test. They will have a digital rectal exam once a year. Participants will have biopsies every 2-3 years. Needles will be put into different parts of the prostate. The needles are guided by ultrasound imaging. Participants will also have targeted biopsies with mpMRI and MRI guided fusion (MRI-US fusion). MRI-US fusion combines previous MRI images with live ultrasound images. For MRIs, participants will lie on their stomach on the scanner table. A coil may be placed in the rectum. Participants will have a physical exam and medical record review at least every 3 years. Their weight and vital signs will be checked. They will give data about their daily activities, side effects, and symptoms. Every 2-3 years, participants will fill out surveys about their prostate health and quality of life. Participants may give blood, urine, prostate secretion, and saliva samples. The samples will be used for research. Participation will last for as long as the participant does not need actual treatment for his prostate cancer. Read Less

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. Read Less
