Two new studies suggest that pediatric medulloblastomas and high-grade gliomas are genetically different from the same tumors in adults. Age-dependent gene expression might affect tumor biology; therefore, therapies for adult medulloblastomas or gliomas might not produce the same clinical outcomes in pediatric patients, and vice versa.
