Official title

A Phase I Trial of Highly Conformal, Hypofractionated, Focally Dose Escalated Post-Prostatectomy Radiotherapy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
