Eliminating Breast Cancer Surgery in Exceptional Responders With Neoadjuvant Systemic Therapy
Tab Title Description
Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study
The goal of this clinical research study is to learn how often breast cancer recurs (returns after treatment) in the breast in patients who have been treated with chemotherapy and have had follow-up radiation therapy (but not surgery) and are in complete remission (no evidence of disease). This is an investigational study. Radiation therapy is delivered using FDA-approved and commercially available methods. The study doctor can explain how radiation therapy is designed to work. About 50 participants will be enrolled on this multicenter study. Up to 50 may take part at MD Anderson.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
Patients may be enrolled prior to, during, or following neoadjuvant systemic therapy provided they meet the following eligibility and ineligibility requirements noted below:
- Pathologically confirmed unicentric invasive breast cancer defined as radiologic clinical stage T1 or T2 (≤ 5 cm), N0 or N1 (≤ 4 abnormal axillary nodes on initial ultrasound), clinical stage M0.
- HER2 positive (IHC 3+ and or FISH amplified) or triple receptor negative (TN, ER/PR < 10% HER2 negative (IHC 1+ or 2+ FISH non-amplified) receiving any standard routine clinical NST regimen.
- Patient desires breast conserving therapy.
- Age 40 years or older. This age cutoff is justified because breast cancers in women under the age of 40 are known to have a significantly higher risk of IBTR presumably due to underlying biologic differences [104, 105].
- Female sex.
- If the patient has a history of a prior non-breast cancer, all treatment for this cancer must have been completed prior to study registration and the patient must have no evidence of disease for this prior non-breast cancer.
- Patient must have an initial nodal ultrasound that does not demonstrate more than four suspicious lymph nodes, any suspicious lymph nodes should be biopsied to determine if nodal metastatic disease present.
- Radiologic evidence for a stage T3 or clinical stage T4 breast cancer.
- Clinical or pathologic evidence for distant metastases.
- Prior diagnosis of invasive or ductal carcinoma in situ breast cancer in the ipsilateral breast.
- Clinical evidence of progression of disease > 20% in the breast or new evidence of nodal metastases.
- Patient is known to be pregnant.
- Patient is participating in a NST protocol in which surgical excision of the breast and or lymph nodes are required.
