Filter by:This study investigates if a new drug (PSMA) makes prostate cancer easier to identify in positron-emission tomography (PET) imaging. If this works, prostate cancer treatments can be prescribed that match the location of the disease. PSMA is radiolabeled with Gallium-68 (Ga-68). This means a participant receives a small dose of radiation from the drug - less than the annual radiation limit for a medical worker. To test this new drug, participants will receive an injection of Ga-68 PSMA and then have a PET scan. This PET scan, and the reported results, will be entered into the medical record and shared with the treating oncologists.
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.

The purpose of this study is to evaluate a new counseling tool for patients deciding whether or not to undergo prostate cancer screening. This screening decision aid is a computer program that provides individual patients estimates of their risks of prostate cancer diagnosis, prostate cancer related death, or death from any cause. The researchers are evaluating whether or not patients find this screening decision aid helpful. As part of this study, participants will be asked for their response on questionnaires. If patients find the screening decision aid helpful, the researchers will make it available at other clinic locations.
The overall goal of this pilot project is to test the hypothesis that a decline in muscle strength precedes the decline in bone strength in men undergoing androgen deprivation therapy (ADT) for prostate cancer. The investigators will measure changes in serum biomarkers involved in muscle-bone crosstalk, anatomic changes in muscle and bone structure and strength that could ultimately contribute to fractures. The findings from this research will inform design of interventions to reduce falls and hip fractures in patients undergoing ADT as well as application to broader populations of at risk patients.
To compare the toxicity, rate of local control, biochemical failure rate and quality of life of three different radiotherapy techniques (moderate hypofractionation, stereotactic body radiotherapy (SBRT) and standard radiotherapy plus 2 fractions of SBRT (BOOSTER)
The purpose of the pre-study screening is to test for DNA abnormalities or biomarkers.
Background: ETBX-011, ETBX-061, and ETBX-051 are cancer vaccines. Their goal is to teach the immune system to target and kill cancer cells. The vaccines target 3 proteins found in many types of cancer. Researchers think targeting all 3 proteins in unison will have the best results. Objective: To test the safety of combining ETBX-011, ETBX-061, and ETBX-051 and their effects on the immune system. Eligibility: People ages 18 and older with advanced cancer that has not responded to standard therapies Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Scan: They will lie in a machine that takes pictures of the body. Participants will receive the 3 vaccines through 3 shots under the skin every 3 weeks for 3 doses, then every 8 weeks for up to 1 year. They will have blood and urine tests at each vaccine visit. They will have scans and other measurements of their tumor after 9 weeks and then at their vaccine visits every 8 weeks. Participants will keep a diary of symptoms at the injection site. Participants will have a visit 90 days after their final treatment. This will include a physical exam and blood and urine tests. If they have any ongoing side effects, they will be followed until these end or are not changing. After this visit, they will be called every 3 months for the first year, every 6 months for the next 2 years, then every 12 months for another 2 years to see how they are doing. Participants will have the option to enroll in a long-term follow-up study. ...
Exposure to radiation can impact immune cells that are present in the blood, such as lymphocytes. It is hypothesized that larger radiation fields and/or longer courses of radiation, result in greater decrease in immune cells. To test this hypothesis, investigators will take blood samples from subjects undergoing two different standard of care radiation regimens for prostate cancer, and subjects undergoing two different standard of care regimens for breast cancer.
The risk of prostate cancer is associated with lifestyle habits, such as diet and physical activity. Indeed, results of numerous studies suggest links between obesity, diabetes, inflammation and androgen and estrogen metabolism in the pathogenesis of prostate cancer. The goal of BIOCaPPE study (Biomarkers and Prostate Cancer/ Prevention and Environment) is to identify biomarkers of prostate cancer risk that are potentially modifiable by environmental exposures (e.g. diet and physical activity). A selection of few of the most promising biological markers will be evaluated in a cohort of more than 2000 men at high-risk of prostate cancer. Such biomarkers would provide a practical approach to identify men at high risk of prostate cancer who could benefit from interventions aiming at reducing their risk. The biomarkers would also be useful to monitor the efficacy of the interventions on patient's lifestyle.
