IRBTR: International Rare Brain Tumor Registry
Study Details
Study Description
Brief Summary
The objective of the International Rare Brain Tumor Registry (IRBTR) is to better understand rare brain tumors through the collection of biospecimens and matched clinical data of children, adolescents, and young adult patients diagnosed with rare brain tumors.

Detailed Description
The International Rare Brain Tumor Registry (IRBTR) is a prospective observational study that will collect tumor samples and matched clinical and radiological data to better understand the outcomes of patients with rare brain tumors in particular: CNS sarcoma, BCOR, MN-1 altered tumors, and other unclassified rare brain tumors.
Data collected include demographics, disease characteristics, treatment information, radiological imaging, and biospecimen collection if available ( tumor tissues Patients will be followed longitudinally to obtain outcome data. Data collection will continue for approximately 10 years.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
CNS Sarcoma Patients diagnosed with Central nervous system (CNS) sarcomas |
|
BCOR-altered Patients diagnosed with tumors characterized by alterations in the BCOR gene. |
|
Astroblastoma/MN-1- altered Patients diagnosed with Astroblastomas/MN-1 alterations |
|
Unclassifiable tumors Patients diagnosed with histologically ambiguous tumors or tumors that fail to classify with the current diagnostic methods. |
|
Other Rare Brain tumors Patients diagnosed with other rare brain tumors that do not meet the criteria for cohorts 1-4. |
Outcome Measures
Primary Outcome Measures
- Event-free Survival [10 years]
The primary outcome measure will be time from diagnosis to an event, defined as the occurrence of progression or recurrence of the disease, occurrence of a second malignant neoplasm, or death from any cause. Each cohort will be analyzed separately.
Secondary Outcome Measures
- Molecular characterization [10 years]
To determine molecular characteristics of each cohort using somatic and germline SNV calling, methylation profiling, fusion calling and gene expression profiling. Molecular findings will be correlated with clinical characteristics to identify risk factors and subgroup-specific therapeutic susceptibilities.
- Radiological characterization [10 years]
To analyze conventional and advanced imaging findings (including diffusion weighted imaging) of each cohort and correlate them with clinical, histopathology and molecular data (radiogenomics).
