What this research studies

If I had glioblastoma, this project would create a small implant called the Tumor Monorail that gives clinicians a safe channel to take tumor samples over time. The team is using materials with a long history of clinical use and has completed biocompatibility testing and FDA pre-submission meetings to prepare the device for human use. The R44 award supports further device development, validation testing, and steps toward clinical deployment. The aim is to provide up-to-date tumor information so doctors can tailor therapies as the tumor evolves.

Who could benefit from this research

Good fit: Ideal candidates would be adults with a confirmed diagnosis of glioblastoma who are medically eligible for a neurosurgical implant and subsequent serial sampling.

Not a fit: People with non-glioblastoma brain tumors, those who are not surgical candidates, or whose tumors are inaccessible for implantation would likely not benefit from this device.

Why it matters

Potential benefit: If successful, the device could help doctors detect recurrence or treatment resistance earlier and tailor therapies more precisely, potentially improving outcomes.

How similar studies have performed: While cerebrospinal fluid reservoirs (e.g., Ommaya) are used clinically for sampling, implantable devices for serial solid tumor biopsies in glioblastoma are largely novel and have limited clinical proof to date.
