ACNS02B3 A Children's Oncology Group Protocol for Collecting and Banking Pediatric Brain Tumor Research Specimens
Medical researchers want to find better ways to find tumors early, to find ways to prevent the occurrence of tumors and to develop better and less toxic therapies. To do this, they need more information about the characteristics of childhood tumors. Researchers would like to study samples of tumor tissues and molecules (tiny particles) in the blood that may be related to tumors, especially malignant (cancerous) tumors.
All patients treated for a brain tumor at a COG institution are eligible for participation in this study. Brain tumor biological specimens, derived from primary tumors of the central nervous system, must be available for submission.
When cancer is suspected, a sample of the tumor is removed for evaluation. Proper identification of the type of tumor may influence decisions about treatment. Any tissue that has already been removed but is not needed to make the diagnosis is usually thrown away. The unused tissue from the diagnostic procedure or surgery will be kept for special research studies. Drawing samples of blood is often a part of the routine evaluation of patients suspected of having cancer. When blood is drawn for routine tests, patients will be asked to give an extra teaspoonful of blood for special research studies. The blood sample may be analyzed for characteristics or molecules that may change in a person with a brain tumor, or it may be compared to the brain tumor itself.
