Type of Human Subjects Involvement:
Internal administration of radioactive substances to human subjects.
The purpose of this protocol is to evaluate functional changes of normal brain tissue in patients undergoing radiation therapy for brain tumors. Approximately 25 patients will be studied, including follow-up patients from prior years. Each patient will be studied up to four times per year: at baseline, after radiation, and two or four months later. The subjects have a short-lived positron emitter tracer (F-18-Fluorodeoxyglucose or F-18-FDG) administered and are subsequently scanned with positron emission tomography (PET). A potential side effect of radiation is the induction of cancer. However, no harm in a human individual or in a large population exposed at doses as low as those delivered in this procedure has been reported. The estimation of risk of harm can be obtained only by extrapolation from much higher doses. Whenever blood is removed or a substance injected by venipuncture, there is minor discomfort and a slight possibility of local bleeding in the tissues.
