This study is for patients that have been diagnosed with prostate cancer. This study will compare metastasis-free survival, determined using conventional imaging, between men with high-risk prostate cancer randomized to ultrahypofractionation (stereotactic body radiation therapy [SBRT]) to those randomized to moderate hypofractionation and conventional fractionation. Participants can expect to remain in the study for 11 years and 10 months.

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 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.

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.

The purpose of this study is to compare the effects of hormone therapy (androgen deprivation) and TAK-700 plus radiation therapy with hormone therapy (androgen deprivation) and radiation therapy on patients with prostate cancer.
There are 2 treatment groups in this study. Group 1will receive hormone therapy plus radiation therapy only and Group 2 will receive hormone therapy and TAK-700 plus radiation therapy.
Subjects will receive hormone therapy for 24 months. Radiation will be given in 44 treatments over approximately 2 months. If the subject is in Group 2 they will take TAK-700 for 24 months. After the subject is finished receiving therapy, the study doctor will ask the subject to visit the office for follow-up exams every 6 months for 3 years and then once a year.
