Exploratory Study of Effects of Radiation Therapy in Pediatric Patients With Central Nervous System Tumors

Completed

Conditions studied: Diffuse Intrinsic Pontine Glioma, PNET, Ependymoma, Germinoma, Medulloblastoma

In brief

This study will analyze the effects of radiation given to children who have tumors of the central nervous system (CNS). Researchers want to learn more about changes in the quality of life that patients may experience as a result of radiation. Patients ages 21 and younger who have a primary CNS tumor and who have not received radiation previously may be eligible for this study. They will have a medical history and physical examination. Collection of blood (about 2-1/2 tablespoons) and urine will be done, as well as a pregnancy test. Patients will complete neuropsychological tests, which provide information about their changes in functioning over time. An expert in psychology will give a number of tests, and the patient's parents or guardian will be asked to complete a questionnaire about the patient's behavior. Also, patients will be given a quality of life questionnaire to complete and vision and hearing tests. The radiation itself is prescribed by patients' doctors and is not part of this study. Magnetic resonance imaging (MRI) will give researchers information about the tumor and brain, through several scanning sequences . MRI uses a strong magnetic field and radio waves to obtain images of body organs and tissues. Patients will lie on a table that slides into the enclosed tunnel of the scanner. They will need to lie still, and medication may be given to help them to do that. They may be in the scanner for up to 2 hours. As the scanner takes pictures, patients will hear knocking or beeping sounds, and they will wear earplugs to reduce the noise. A contrast agent will be administered, to allow images be seen more clearly. Blood and urine tests will be conducted after the first dose of radiation. MRI scans will be done 2 weeks after patients finish radiation therapy and again at 6 to 8 weeks, 6 months, 12 months, and yearly. Also at those follow-up periods, patients will undergo similar procedures as previously, including blood and urine tests and neuropsychological testing. Patients can remain in this study for 5 years. ...
