Mini tumors in a dish could guide breast cancer therapy
NCT ID NCT06468124
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study is growing miniature versions of breast cancer tumors, called organoids, from samples taken during surgery. Researchers want to see if these lab-grown organoids can predict how well a patient's cancer will respond to treatments like chemotherapy or radiation. If the organoids' sensitivity matches the patient's actual outcome, this approach could one day help doctors personalize cancer therapy. The study involves 20 adults with breast cancer that has spread to the brain or other parts of the body.
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 lab test that helps doctors choose the most effective treatment for each patient's breast cancer metastases.
- What could go wrong
- This is a very small, early study with only 20 participants. It is designed to gather data, not to test a new treatment, so it may not lead to immediate changes in care.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Breast cancer patients with resectable brain or extra-cranial metastases and undergoing postoperative radiotherapy or palliative radiotherapy to extracranial metastases if necessary +/- other systemic treatments after resection. Patients who will undergo a biopsy of the extra-cranial metastases may be recruited and asked to consent for an additional research biopsy at the same time as standard of care biopsy.
