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: - Few studies or literature are available about the long-term safety of repeated peptide vaccinations in people over a period of time. Long-term vaccination may be needed to control tumors. Researchers gave a group of men a series of vaccine injections over 2 years. Now they want to give those same men the new version of the vaccine. They want to see if it produces different types of immune responses and also ensure that repeated vaccinations are safe. Objectives: - To find out the long-term safety of repeated T-cell receptor alternate reading frame protein (TARP) peptide vaccinations. Eligibility: - Men who took part in National Cancer Institute (NCI) protocol 09-C-0139. Design: - Participants will be screened with blood tests, scans, physical exam, medical history, and an evaluation of how well they perform everyday activities. - Participants will have apheresis. Blood will be removed with a needle from one arm. A machine will separate the white blood cells. The blood, minus the white cells, will be returned through a needle in the other arm. - Participants will have 14 visits. At each visit, they will have a physical exam and blood tests. They will discuss any side effects. - Participants will get vaccine injections at weeks 3, 6, 9, 12, 15, and 24. The vaccine will be made from the participants own cells. - Participants will get a Vaccine Report Card to complete after receiving vaccine. - The study lasts 96 weeks.
