Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients of all ages undergoing neurosurgery for suspected or confirmed CNS tumors, as well as pediatric patients without CNS tumors undergoing neurological procedures.

Probably not a fit

Patients who are not undergoing neurosurgery or do not have a CNS tumor diagnosis may not receive any benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to enhance understanding of central nervous system (CNS) tumors by collecting tissue samples during surgeries and post-autopsy. The collected samples will undergo various analyses, including DNA and RNA extraction, sequencing, and drug screening to develop new treatment options. The research will also involve creating tumor cell lines and patient-derived xenografts to test responses to different drugs. Additionally, biological samples from pediatric patients without CNS tumors will be collected for comparative analysis.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment options and new therapeutic targets for patients with CNS tumors.

How similar studies have gone: Other studies have shown promise in using tissue samples for drug screening and analysis in cancer research, indicating that this approach has potential for success.
