Blood test could replace brain surgery for tumor tracking
NCT ID NCT05925218
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to develop a liquid biopsy—a blood test—to detect tumor DNA in patients with high-grade gliomas, an aggressive type of brain cancer. Researchers will collect blood samples from 70 patients before and after standard radiotherapy to see if they can measure tumor changes without surgery. The goal is to create a non-invasive way to monitor how the tumor responds to treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple blood test to monitor brain tumors, reducing the need for invasive biopsies.
- What could go wrong
- This is an early feasibility study with only 70 participants, so the test may not be sensitive enough or may not work for all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients can be enrolled either prior to a planned surgery/biopsy for a suspected HGG or after biopsy/surgery of pathologically proven, previously untreated HGG, prior to adjuvant radiotherapy * Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate * Age ≥18 yrs Exclusion Criteria: * History of another invasive malignancy, except for non-melanoma skin cancer or tumors curatively treated with no evidence of disease for ≥ 2 years.
