Filter by:Firefighters have been shown to be at increased risk for various types of cancer, including prostate cancer. This study will try to explore possible reasons for this increase in risk. A study group at the Cancer Registry of Norway is creating a cohort of Norwegian firemen employed from 1960 onwards. A job exposure matrix (JEM) is also being constructed, examining different types of exposure to potentially cancer-inducing agents and activities, and how these have changed historically. Examples include exposure to fire-smoke, shiftwork, diesel exhaust and regular health check-ups. By linking the cohort with data from the Cancer Registry of Norway and the JEM the investigators can examine which exposure assessments, if any, are related to an increased risk of prostate cancer.
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 dominating problem after local radiotherapy of prostate cancer is rectal toxicity. If the rectum could be completely moved out of the treated volume, a substantial decrease of rectal toxicity seems reasonable. In this study we will develop and evaluate a new transrectal injection technique where hyaluronic acid (HA) is injected in the space between the prostate and the rectum prior to external beam radiotherapy to increase the physical distance between prostate and rectum.
