Filter by:Background: Sometimes prostate cancer comes back after a person s prostate is removed. In this case, radiation is a common treatment. Radiation kills prostate cancer cells. It can be very effective. It is usually given in short doses almost every day for 6 or 7 weeks. Researchers want to see if a shorter schedule can be as effective. They want to see if that causes the same or fewer side effects. Usually, radiation is used to treat the entire area where the prostate was before surgery. In some patients, an area of tumor can be seen on scans. Researchers are also trying to see if they can give less dose to the area usually treated with radiation if the full dose is given to the tumor seen on scans. Objective: To find the shortest radiation schedule that people can tolerate without strong side effects. Eligibility: People at least 18 years old who have had a prostatectomy and will get radiation Design: Participants will be screened with: - Medical history - Physical exam - Blood and urine tests - Scan that uses a small amount of radiation to make a picture of the body - Scan that uses a magnetic field to make an image of the body - Participants will provide documents that confirm their diagnosis. - Participants may have a scan of the abdomen and pelvis. Before they start treatment, participants will have another physical exam and blood tests. Participants will get radiation each day Monday through Friday. Treatment may last 2, 3, or 4 weeks. Participants may provide a tissue sample from a previous procedure for research. Participants will answer questions about their general well-being and function. About 4-5 weeks after they finish radiation treatment, participants will have a follow-up visit. They will be examined and give a blood sample. They will have 6 follow-up visits for the next 2 years.
Background: Metastatic castrate-sensitive prostate cancer is cancer that has spread beyond the prostate area. It can be controlled by lowering the amount of testosterone in the body. This is called androgen deprivation therapy (ADT). The vaccine PROSTVAC might help the immune system kill cancer cells. Researchers want to add PROSTVAC and docetaxel chemotherapy to ADT. They think this may work better against prostate cancer than ADT alone. Objective: To test if adding PROSTVAC and docetaxel to ADT works better against prostate cancer than ADT alone. Eligibility: Men ages 18 years and over with metastatic castrate-sensitive prostate cancer Design: Participants will be screened with: Physical exam Medical history Blood tests Possible computed tomography (CT), magnetic resonance imaging (MRI), or bone scan: Participants lie in a machine. The machine takes pictures of the body. Electrocardiogram: Soft electrodes are stuck to the skin to record heart signals. Participants will have 2 optional tumor biopsies during the study. Participants will join 1 of 2 groups. Both groups will get: ADT Docetaxel by vein Steroids by mouth or vein before each docetaxel infusion PROSTVAC injection Both groups first have ADT. One to 4 months after, they have: Group A: Docetaxel every 3 weeks for 6 cycles PROSTVAC 3 weeks after the last infusion Booster injections 2 weeks later and then every 3 weeks, for 6 boosters total Group B: PROSTVAC Booster 2 weeks later Docetaxel hours later Docetaxel and the booster every 3 weeks for 6 cycles Participants will have a visit 4-5 weeks after the last treatment. They will then have visits every 12 weeks. Participants will be followed for up to 15 years. This includes physical exams every year for 5 years.
