About this study

Official title: Selective Use of Observation After Lumpectomy and Sentinel Lymph Node Biopsy in Her-2 Positive Patients With Pathologic Complete Response to Neoadjuvant Chemotherapy

The primary objective of this study is to describe the rate of local control in patients with her-2 positive early stage breast cancer with a complete response to chemotherapy and lumpectomy alone.

Read the detailed description

Participants, ages 40 and older diagnosed with stage I or stage II her-2 positive, node negative breast cancer patients will be recommended to continue trastuzumab +/- pertuzumab therapy after surgery to complete a full year of therapy as standard of care under the clinical management of the patient's medical oncologist.

Once neoadjuvant chemotherapy has been completed, the patient will be separated in to one of three arms based on a set of criteria for each. If the patient wishes to take part in the study, but does not have a lumpectomy with sentinel lymph node biopsy showing pCR, the patient will be placed in to Arm C and will proceed with radiation as standard of care. If the patient wishes to take part in the study, and has a lumpectomy with sentinel lymph node biopsy showing pCR, but does not agree to omission of radiation, the patient will be placed in to Arm B and will proceed with radiation as standard of care. If the patient wishes to take part in the study, and has a lumpectomy with sentinel lymph node biopsy showing pCR and agrees to omission of radiation, the patient will be placed in to Arm A with follow up assessments occuring at 1 month post-op, and every 3 months up to 5 years post-op.

Data will be collected on local, regional and distant recurrence at each follow-up.The self-administered FACT-B+4 quality of life questionnaire will be given to patients at baseline, at first postoperative visit, and at the one year post-operative visit.

Patients enrolling prior to chemotherapy will be asked to fill out the Breast-Q™ at the time of their first surgical consultation. Patients enrolled post-surgery will be asked to fill out the Breast-Q™ at their first post-operative visit. All patients will be asked to fill out the Breast-Q™ at their yearly postoperative visits. The Breast-Q™ is a validated patient assessment of breast cosmesis. This tool has both pre operative and post-operative components. Pre-operative Breast-Q™ questionnaire data is not required of participants in this study who enroll postoperatively.

What participants receive

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

  • Omission of RadiationRadiation

    No Radiation will be given. 1 year of trastuzumab +/- pertuzumab treatment will be given with 5 years of follow up occurring every 3 months to check for recurrence

Study groups in NCT03460067
Study groupRoleWhat they receive
Arm AExperimentalPatient is required to have lumpectomy with sentinel lymph node biopsy shows pCR and will complete 1 year of trastuzumab +/- pertuzumab treatment. No radiation, or an omission of radiation, will be given on this arm, including external beam, brachytherapy or intraoperative radiation. Patients will be required to follow up with a medical, surgical, or radiation oncologist every 3 months for 5 years. At these follow up visits, a physical exam will be performed to assess for any disease recurrence. Screening mammogram or MRI is recommended every 6 months for patients on this arm.
Receives: Radiation: Omission of Radiation
Arm BNo interventionPatient is required to have her-2 positive breast cancer, clinically node negative from exam. Patient will complete neoadjuvant chemotherapy per Medical Oncologist. This arm will undergo lumpectomy with sentinel lymph node biopsy shows pCR. The patient will proceed with radiation as standard of care. This arm includes a review of outcomes in the patient's medical chart as well as a collection of biospecimens such as blood and urine, for correlative studies.
Arm CNo interventionPatient is required to have her-2 positive breast cancer, clinically node negative from exam. patient will complete neoadjuvant chemotherapy per Medical Oncologist. This arm will not undergo lumpectomy with sentinel lymph node biopsy shows pCR. The patient will proceed with radiation as standard of care. This arm includes a review of outcomes in the patient's medical chart as well as a collection of biospecimens, such as blood and urine, for correlative studies.

What is being measured

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

  1. Ipsilateral Breast Cancer Recurrence

    Defined as biopsy positive her-2 positive tumor in the same breast

    Measured: up to 5 year post-op

Secondary outcomes (6)
  1. Regional Nodal Recurrence

    Will include recurrence in the ipsilateral draining axilla, supraclavicular fossa, or internal mammary nodes.

    Measured: 1 month post-op, every three months post-op for 5 years

  2. Distance Metastasis

    Defined as biopsy proven disease outside of the affected breast and draining lymphatics, or definitive radiographical evidence of distant disease, to include a positive bone scan or enhancing lesions on MRI brain.

    Measured: 1 month post-op, every three months post-op for 5 years

  3. Overall Survival

    Defined as death from any cause

    Measured: 1 month post-op, every three months post-op for 5 years

  4. Quality of Life using FACT-B+4

    Measured using scores from patient reported outcomes from FACT-B+4 questionnaire

    Measured: 1 month post-op, every three months post-op for 5 years

  5. Cosmetic (Breast) Outcomes

    Measured using scores from patient reported outcomes using the Breast Q questionnaire

    Measured: 1 month post-op, every three months post-op for 5 years

  6. Lymphedema Rate

    Assessed by a diagnosis of Lymphedema in the medical record by trained lymphedema nurse.

    Measured: 1 month post-op, every three months post-op for 5 years

Questions about this trial

What is this clinical trial studying?

A study testing Omission of Radiation in people with HER2-positive Breast Cancer, run by University of Kansas Medical Center 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 15 inclusion and 3 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: under way, not looking for participants, as of the sponsor's last update on 27 Mar 2025. 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?

This study is still under way. Results are not available in the source record yet.

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?

Ipsilateral Breast Cancer Recurrence (time frame: up to 5 year post-op). 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 27 Mar 2025.
