What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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.
