Could brain MRIs and spinal taps predict breast cancer spread?
NCT ID NCT05130840
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study explores whether routine brain MRIs and spinal taps can detect early signs of breast cancer spreading to the brain in people with HER2-positive breast cancer. Researchers will enroll 9 participants to see if these tests are feasible and well-tolerated. The goal is to catch brain metastases before symptoms appear, enabling earlier 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 approach could help detect brain metastases earlier in HER2+ breast cancer patients, allowing for prompt treatment and possibly preventing disease progression.
- What could go wrong
- This is a very small feasibility study with only 9 participants, so results may not apply to all patients. The procedures (MRI and lumbar puncture) may be uncomfortable or not tolerated by everyone.
