Brain scans every 6 months could catch cancer spread earlier in stage IV breast cancer
NCT ID NCT07357298
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase III trial is testing whether routine brain MRIs every 6 months can detect brain metastases earlier in people with stage IV breast cancer who have no symptoms. Participants are randomly assigned to either scheduled scans or standard care (scans only if symptoms appear). The goal is to see if earlier detection changes treatment options and improves outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Surveillance Brain MRI
- What this could lead to
- If successful, this could show that regular brain scans help catch metastases earlier, potentially reducing the need for whole-brain radiation and improving quality of life.
- What could go wrong
- This is a phase III trial, but it's still relatively small (156 participants) and focuses on detection, not a direct treatment. Earlier detection may not always improve survival or outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histologic diagnosis of breast cancer with documentation of ER/PR/HER2 status * Radiographic evidence of stage IV extracranial disease enrolled within 60 days of diagnosis or starting first line therapy. HR+/HER2- patients may be enrolled within 60 days of starting 2nd line therapy as well. * HR+ will be defined as ER and/or PR \> 10%. To be classified as HER2+ disease, overexpression of HER2 by either IHC or in-situ hybridization is necessary as defined by the ASCO / CAP Guidelines41. Triple negative will be classified as ER and PR \<10% and HER2-. * Age ≥ 18 * Life expectancy ≥ 6 months * Eastern Cooperative Oncology Group performance status ≤ 2 * Patients must be able to understand and the willingness to sign an informed consent for study procedures * Stated willingness to comply with all study procedures and availability for the duration of the study Exclusion Criteria: * Prior diagnosis or treatment of brain metastases or leptomeningeal disease * History of other non-breast malignancy requiring treatment with the exception of those with a negligible risk of metastasis or death (e.g., 5-year OS of \> 90%), such as but not limited to, non-melanoma skin cancers, stage I endometrioid uterine cancer, and others at the discretion of the PI * Neurologic symptoms warranting standard screening brain MRI in the judgement of the treating physician at time of enrollment * Indications warranting brain MRI for other neurologic conditions at time of study entry (including multiple sclerosis, stroke, traumatic brain injuries, epilepsy, hydrocephalus and pituitary gland disorders) * Contraindication towards MRI with contrast * Chronic kidney disease stage IV or V or end stage renal disease (CrCl \<30 ml/min)
