What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a high-precision radiation technique called SBRT for people with advanced breast cancer who cannot have surgery. Twenty-four participants will receive four radiation doses over two weeks. Researchers will track side effects and quality of life to see if this approach is safe and effective.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
stereotactic body radiation therapy (SBRT)
What this could lead to
If successful, SBRT could offer a non-surgical option to control breast tumors in patients with advanced or inoperable cancer.
What could go wrong
This is a small, early-phase study (24 people) focused on safety and side effects. It may not lead to a standard treatment, and radiation can cause skin irritation, fatigue, or other side effects.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 24 people

The number the study aims to enrol. It can still change while the study runs.

Inclusion Criteria: Histologically confirmed diagnosis of invasive breast carcinoma of non-lobular histology. Unifocal tumour Previously assessed by a breast surgeon and medical oncologist, with no surgery being recommended at time of enrollment. Primary breast and axillary surgery not recommended/performed due to any of the following: * distant metastatic disease * unresectable T4 disease and/or * medically inoperable and/or * patient declined breast surgery Stages T1-T4, N1-N2, M0-M1 disease Ability to attend radiation planning and therapy, able to attend for follow-up care Able to provide written informed consent. Exclusion Criteria: Received chemotherapy within 3 weeks prior to breast SBRT. (Concurrent endocrine therapy is permitted) Multifocal or multicentric tumours. Ipsilateral supraclavicular or infraclavicular nodal disease \>= 1cm size that is at the level of or superior to the brachial plexus Unable to meet the brachial plexus dose constraints despite compromising coverage of target volumes - as per the discretion of the treating physician Treatment target volume estimated to occupy \> 50% of the ipsilateral whole breast volume. Locally recurrent breast cancer, with previous radiotherapy to the breast, or previous lumpectomy or mastectomy. Ipsilateral breast implant. Serious non-malignant disease that precludes definitive surgical or radiation treatment (e.g. scleroderma, systemic lupus erythematosus, cardiovascular/pulmonary/renal disease). Women who are pregnant or lactating. Psychiatric or addictive disorders that preclude obtaining informed consent or adherence to protocol
