  • Women only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Understand and voluntarily sign an informed consent document prior to conducting any study related assessments or procedures.

  • Must have marker clip indicating location of target tumor in breast.
  • Unifocal tumor less than or equal to 2 cm based on contrast-enhanced prone-breast MRI.

About this study

Official title: A Phase II Study of Preoperative Stereotactic Ablative Body Radiotherapy (SABR) for Early-Stage Breast Cancer: Introduction of a Novel Form of Accelerated Partial Breast Radiotherapy

This study involves a course of radiation to the tumor that is delivered BEFORE surgery. The type of radiation is called stereotactic ablative body radiation therapy (SABR). The purpose of this study is to evaluate the effects, good and/or bad, of pre-operative SABR specifically focusing on its ability to reduce the chances that additional breast surgery will be needed, reducing the amount of breast/heart/lung tissue that is irradiated, and to study the tumor-tissue effects of SABR. The usual treatment for patients with early-stage breast cancer who have breast-conserving treatment (BCT) is to receive radiotherapy AFTER surgery, targeting either the whole breast or part of the breast.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Standard of Care Schedule Variation: SABROther

    Also called radiotherapy, Stereotactic Ablative Body Radiation Therapy (SABR)

    SABR will be delivered over 3 days, prior to surgery.

  • Breast-conserving SurgeryProcedure or surgery

    Breast-conserving surgery will be scheduled for 6-8 weeks after SABR and will be conducted by a Moffitt breast surgeon.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of Pathologic Complete Response (pCR)

    Rate of pathologic complete response following pre-operative SABR for early-stage breast carcinoma. pCR: The absence of residual invasive disease in the breast and in the axillary lymph nodes at the completion of the neoadjuvant treatment.

    Measured: 6 weeks post SABR

Questions about this trial

What is this clinical trial studying?

A study testing Breast-conserving Surgery in people with Breast Cancer and Breast Cancer Female, run by H. Lee Moffitt Cancer Center and Research Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 17 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 23 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Dec 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of Pathologic Complete Response (pCR) (time frame: 6 weeks post SABR). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03137693, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Feb 2023.
