Primary Outcome Measures:
  • Genome-wide expression patterns of RNA in tumor samples, normal brainstem tissue and cerebrospinal fluid using Affymetrix gene expression profiling [ Time Frame: 4 years ]
  • Validation of results of the genome-wide analysis [ Time Frame: 4 years ]
  • Proteomic profiling of tumor, normal brainstem tissue and cerebrospinal fluid [ Time Frame: 4 years ]
  • Protein expression patterns as assessed by immunohistochemistry and western blot compared to normal brainstem tissue [ Time Frame: 4 years ]
  • Genome-wide analysis of tumor samples and normal brainstem tissue [ Time Frame: 4 years ]
  • In vitro and in vivo molecular analysis of collected samples [ Time Frame: 4 years ]
    Collected samples will potentially be used for in vitro analysis and generation of animal models of this tumor.

Secondary Outcome Measures:
  • Assess aspects associated with specimen acquisition, including potential benefits and drawbacks [ Time Frame: 4 years ]

Biospecimen Retention:   Samples With DNA
Cerebrospinal fluid, serum, urine, brainstem tumor and constitutional tissue from patients with diffuse intrinsic pontine glioma or brainstem glioma will be collected.

Estimated Enrollment: 100
Study Start Date: April 2010
Estimated Study Completion Date: April 2030
Estimated Primary Completion Date: April 2025 (Final data collection date for primary outcome measure)
Patient samples
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

Detailed Description:
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.
