Cerebrospinal Fluid Biomarkers for Brain Tumors

This observational study is collecting cerebrospinal fluid (CSF) samples from people with brain tumors. CSF is the fluid surrounding your brain and spinal cord. Researchers hope to find "biomarkers" – measurable indicators of disease – in these samples that could help doctors better diagnose, monitor, and treat brain tumors. The study aims to gather enough samples to be a valuable resource for the research community. You may be eligible if you are 18 years or older and have any type of tumor involving your central nervous system (brain, spine, or surrounding structures). The study is currently unclear on its recruitment status and plans to enroll 400 participants.

Study design
This is an observational study with a planned enrollment of 400 participants. It is not a treatment study.
What's involved
You would undergo collection of CSF samples via lumbar puncture at least two times. You may also choose to provide additional CSF samples.
Compensation
Not stated in the trial record.
Follow-up
After completion of study treatment, patients are followed up periodically.

Eligibility criteria

Inclusion

Any evidence of neoplasm involving the central nervous system (CNS) or its adjacent structures in contact with CSF. Such lesions may include but are not limited to intra-axial or extra-axial lesions, which could be benign, malignant or as yet undefined, involving the brain, spine, meninges, nerves, or vasculature or supporting structures
Subjects must be 18 years of age or older

Exclusion

Patients who are under 18 years of age or are a member of a vulnerable population will be excluded from this study
Pregnant women or women who may be pregnant are specifically excluded from study participation
Exception will be granted for patients with diminished capacity to consent if a legally authorized representative is available
Patients without clinical or radiographic evidence of a potentially neoplastic CNS lesion will be excluded
Patients with an inability or unwillingness of individual or legal guardian/representative to give written informed consent will be excluded
Any patient for whom a clinical contraindication exists to the intended route of CSF access will be excluded. For example, a patient with a large posterior fossa mass lesion at risk of herniation, or a patient with coagulopathy, or other contraindication to lumbar puncture would not be eligible to participate via use of lumbar puncture for CSF access
