This study is for men who have high-risk prostate cancer who plan to be treated with a combination of radiation and hormonal therapy. A tumor genomic analysis (Decipher score) will be used to divide the subjects into two groups. Those with a low genomic risk score will be randomized to either standard treatment with radiation and 24 months of hormonal therapy or to radiation with a shorter, 12 month, course of hormone therapy. Those with a higher genomic risk score or who have lymph node involvement will be randomized to standard treatment with radiation and 24 months of standard hormonal therapy or radiation with 24 months of intensified hormonal therapy.

This study is for patients that have been diagnosed with prostate cancer. The purpose of this study is to directly compare photon (X-ray) therapy and proton therapy to determine which one has better disease control and fewer patient-reported and physician-reported side effects. Participants can expect to be in this study for a minimum of 3 years and up to 10 years, depending on funding.

The Sponsor of this research study is trying to develop a new experimental diagnostic blood test that may help detect colorectal cancer and other diseases. A diagnostic test identifies a specific disease or condition. Experimental means the test has not received approval by the United States Food and Drug Administration (FDA) for sale.
The main goal of this research study is to collect health information and blood samples from people who are going to have a standard-of-care screening colonoscopy. The blood samples along with other health information from patients who take part in the study may help the Sponsor develop new diagnostic tests that may help detect cancer or other diseases in other patients in the future.

This study is for patients who are 18 years and older that have been diagnosed with metastatic castration-resistant prostate cancer (mCRPC).The investigational drugs in this study are Nivolumab and Ipilimumab.The purpose of this research study is to test the effectiveness (how well the drug works), safety, and tolerability of different dosing regimens containing nivolumab plus ipilimumab, ipilimumab alone, or cabazitaxel plus prednisone or prednisolone in participants with metastatic castration-resistant prostate cancer (mCRPC).Duration of this study will take approximately 24 months.

The ProSpace balloon is being studied to test if it will temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating that space will reduce the radiation dose delivered to the anterior rectum. The ProSpace balloon is composed of a bioresorbable polymer material called RESOMER. RESOMER is well studied and approved for many indications. This study will show if it will maintain that space for the entire course of prostate radiotherapy treatment and then be completely absorbed by the body over time. The balloon is considered a permanent implant because it will remain in the body for at least 30 days. The ProSpace System study will collect data to demonstrate the safety and efficacy of its indication. This device is currently investigational in the United States

This study is for men who have prostate cancer. The purpose of this study is to compare the effects, good and/or bad, of adding either prostate removal surgery or radiation therapy of the prostate to standard systemic therapy (SST), which is used to treat prostate cancer.

This study is for patients with prostate cancer that has a risk of getting worse. The purpose of this study is to compare any good and bad effects of using stereotactic body radiation therapy (SBRT), a technique that gives treatment in a shorter amount of time compared to the usual radiation therapy.

This study is for patients that have prostate cancer that has spread and are either beginning hormone therapy for the first time or have been on hormone therapy for less than 30 days. The purpose of this study is to find out what effects (good and/or bad) there are to adding the new investigational drug TAK-700 (also called orteronel) to standard hormone therapy which is used to treat prostate cancer as compared to the standard of hormone therapy alone. The combination of TAK-700 and standard hormone therapy is considered experimental.

The purpose of this study is to compare the effects of hormone therapy (androgen deprivation) and radiation therapy to the prostate gland and seminal vesicles with hormone therapy and radiation therapy to the whole pelvic body area to determine which is better.

There are 2 treatment groups in this study:
1) Patients who receive hormone therapy plus radiation therapy to the prostate gland and seminal vesicles
2) Patients who receive hormone therapy plus radiation therapy to the whole pelvis

This study is for patients with prostate cancer. The purpose of this study is to compare the effects of dose-escalated radiation therapy with or without hormone therapy on your prostate cancer.
There are 2 treatment groups in this study:
1) Patients who receive radiation therapy only
2) Patients who receive radiation therapy plus hormone therapy
Patients will receive 44 radiation treatments over approximately 2 months. If the patient chooses to receive the brachytherapy implant, he will receive 25 daily treatments plus the implant procedure over a timeframe of approximately 6 weeks. Hormone therapy, if given, will last 6 months. After patients are finished receiving therapy, the study doctor will ask them to visit the office for follow-up exams at 3, 6, 9, and 12 months after finishing radiation treatment, every 6 months for 4 years, and yearly thereafter.
