Molecular Analysis of Samples From Patients With Diffuse Intrinsic Pontine Glioma and Brainstem Glioma
The purpose of this study is to prospectively collect specimens from pediatric patients with diffuse intrinsic pontine glioma or brainstem glioma, either during therapy or at autopsy, in order to characterize the molecular abnormalities of this tumor.

Fresh-frozen and fixed tumor samples, correspondent normal brain tissue samples, cerebrospinal fluid, urine, and serum samples from patients affected with diffuse intrinsic pontine glioma or brainstem glioma
High grade diffuse intrinsic pontine glioma (DIPG) accounts for approximately 80% of pediatric brainstem tumors and 10% of pediatric brain tumors, and is the most lethal form of brainstem gliomas in children. There is currently no effective therapy to treat these tumors. We hypothesize that this tumor exhibits unique molecular abnormalities leading to altered RNA and protein expression. The aim of this trial is to collect specimens from pediatric patients with diffuse intrinsic pontine glioma including serum, cerebrospinal fluid, urine, brain tumor and other constitutional tissue, during therapy and/or at autopsy. Our goal is to study this tissue to characterize the genetic abnormalities that lead to tumor formation in order to identify key molecules as biomarkers which we can target to design and test new and more effective treatments.
