About this study

Official title: A Phase II Study of Preoperative Single Fraction Stereotactic Body Radiotherapy to the Intact Breast in Early Stage Low Risk Breast Cancer: Analysis of Radiation Response

This is a Phase II trial of preoperative stereotactic radiation to the breast for low risk breast cancer.

Read the detailed description

This is a single arm phase II study design, evaluating the pathologic response (primary endpoint) as well as toxicity, cosmetic outcome, quality of life, and translational correlates (secondary endpoints) to pre-operative stereotactic body radiotherapy (SBRT) to intact breast tumors in patients with hormone-receptor positive early stage breast cancer.

What is being measured

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

  1. Treatment Response Measured by Residual Cancer Burden (RCB)

    Number of participants with Residual Cancer Burden (RCB) designation 0 (also known as pathologic complete response (pCR)), and RCB I designation (combined endpoint of either of those designations) 4-6 weeks after pre-operative SBRT to intact breast tumors.

    Measured: 4-6 weeks

Secondary outcomes (5)
  1. Number of Participants With Treatment-related Toxicity

    The number of participants with severe acute toxicity, defined as any CTCAE v4 grade 3 or higher toxicity noted from RT delivery up to 90 days after completion of surgery, up to 4 months.

    Measured: RT delivery up to 90 days after completion of surgery, up to 4 months

  2. Cosmetic Outcome (Patients)

    Number of patients who report poor cosmetic outcomes from patient perspective at 90 days after pre-operative SBRT to intact breast tumors using the Radiation therapy oncology group (RTOG) cosmesis scale and digital images.

    RTOG Cosmesis Scale: 1 (excellent), 2 (good), 3 (fair), and 4 (poor)

    Measured: 90 days

  3. Local Recurrence

    To measure local recurrence in participants

    Measured: 1 year

  4. Breast Cancer Treatment Outcomes Scale (BCTOS)

    To assess patient reported satisfaction and quality of life with treatment using the Breast Cancer Treatment Outcomes Scale (BCTOS). The BCTOS is a questionnaire that evaluates the aesthetic and functional outcomes of breast conserving surgery (BCS). Patients rate each item on the questionnaire using a four-point Likert scale, with 1 indicating no difference and 4 indicating a large difference between the treated and untreated breast. Score range 22-88. Higher scores indicate higher difference.

    Measured: Pre and Post surgery (Up to 3 years)

  5. Cosmetic Outcome (Provider)

    Number of providers who report poor cosmetic outcomes from provider perspective at 90 days after pre-operative SBRT to intact breast tumors using the RTOG (Radiation therapy oncology group) cosmesis scale and digital images.

    RTOG Cosmesis Scale: 1 (excellent), 2 (good), 3 (fair), and 4 (poor)

    Measured: 90 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Stereotactic Body Radiation Therapy SBRT in people with Breast Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins at 2 sites 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 11 inclusion and 9 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 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Sep 2024). 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?

Treatment Response Measured by Residual Cancer Burden (RCB) (time frame: 4-6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 Sep 2024.
