What this research studies

If you have glioblastoma, researchers will try to find bits of tumor DNA circulating in your blood to create a personalized fingerprint of your tumor. They will collect blood samples and compare the cell-free DNA to tumor-specific changes to improve detection despite background normal DNA. The team plans to use highly sensitive methods tailored to each patient’s tumor to distinguish true recurrence from treatment effects like pseudoprogression. The goal is a less invasive way to guide care and follow disease over time.

Who could benefit from this research

Good fit: Adults with glioblastoma, including those with unclear MRI results or suspected recurrence, would be the ideal candidates for participation.

Not a fit: People without glioblastoma, or whose tumors shed very little tumor DNA into the bloodstream, are unlikely to benefit from this approach.

Why it matters

Potential benefit: If successful, this could allow earlier and less invasive detection of tumor recurrence and reduce the need for risky brain biopsies.

How similar studies have performed: Blood-based tumor DNA tests have worked well for some other cancers, but prior attempts in glioblastoma have been challenging and this project builds on newer, more personalized detection methods.
