The College of American Pathologists Neuropathology Committee (pictured, minus the illustrious Dr. Aaron Wagner) poses the following question to the neuropathology community worldwide:

"If you were constructing a panel of eight biomarkers there were well-established prognostic/predictive markers for CNS neoplasms, what markers would be included? Note: this is not for diagnosis, but for predicting behavior and should include adult and pediatric brain tumors and can include immunohistochemical and molecular tests."
