Is this trial a fit for you?

Likely a good fit

Ideal candidates include children aged 4 to 21 years with a diagnosis of primary CNS tumors or metastatic disease to the CNS who are expected to survive for more than one year.

Probably not a fit

Patients with secondary health conditions affecting cognitive functioning or those unable to participate in computer-based testing may not benefit from this study.

What this trial studies

This observational study aims to evaluate neurocognitive performance in pediatric patients diagnosed with central nervous system tumors who are undergoing proton beam radiation therapy (PBRT). The researchers will conduct baseline neurocognitive assessments before the first week of radiation and follow-up evaluations 6-12 months post-treatment, with annual assessments thereafter. The goal is to analyze how factors such as age at diagnosis, tumor location, and radiation dose influence cognitive outcomes. This study addresses a significant gap in prospectively-collected data regarding the effects of PBRT on cognitive function in children.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into how proton therapy impacts cognitive outcomes in children, potentially leading to improved treatment protocols.

How similar studies have gone: While modeling studies suggest that PBRT may enhance cognitive outcomes, this study is among the first to prospectively collect patient data on this topic.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Diagnosis of primary CNS tumor or diagnosis of metastatic disease to the CNS with an expected overall survival of \> 1 year. Any prior treatment (chemo, XRT, or surgery) is allowed.
* Planning to receive PBRT to treat the CNS tumor. Patients who have already received PBRT for this disease may also be enrolled provided they completed the NIH Toolbox Cognitive Battery prior to the first week of radiation therapy.
* Between 4 and 21 years of age (inclusive).
* Life expectancy of at least one year.
* Absence of visual impairment that would impede computer testing.
* No secondary health conditions that would impact cognitive functioning (e.g. psychiatric or developmental disability unrelated to cancer).
* Able to understand and willing to sign IRB-approved written informed consent document (or signature of legally authorized representative).
