Brief Summary:
This phase II trial studies how well biopsy of breast after chemotherapy works in predicting pathologic response in patients with stage II-IIIA breast cancer undergoing breast conserving surgery. Tumor tissue collected from biopsy before surgery may help to check if chemotherapy destroyed the breast cancer cells and may be compared to the tumor removed during surgery to check if they are the same.

Invasive Breast Carcinoma Stage II Breast Cancer Stage IIA Breast Cancer Stage IIB Breast Cancer Stage IIIA Breast Cancer Procedure: Biopsy of Breast Phase 2

Detailed Description:

PRIMARY OBJECTIVES:

I. To assess the accuracy of post-neoadjuvant systemic therapy (NST) image-directed tumor bed biopsy for pathologic complete response (pCR), defined as resolution of both invasive disease and ductal carcinoma in situ (DCIS), in cases of clinical and radiologic complete response with trimodality imaging.

SECONDARY OBJECTIVES:

I. To collect axillary pathology results, surgical staging methods (sentinel lymph node biopsy and/or axillary lymph node dissection), and management (surgery and/or radiation) in order to determine axillary nodal response to neoadjuvant chemotherapy and its relationship to breast pCR.

II. To correlate imaging results with pathologic nodal status following neoadjuvant chemotherapy for future planning of axillary management in the next study.

III. To retrospectively assess the negative predictive value (NPV) of a trimodality imaging algorithm in combination with the tumor bed biopsy for predicting pCR.

IV. To collect all trimodality imaging data to determine which combination of the trimodality imaging best identifies the group achieving pCR.

V. To correlate the number of needle cores and tumor bed clip retrieval with the NPV of the tumor site biopsy.

VI. To determine the clinical, imaging, pathologic, and molecular tumor factors associated with the highest NPVs of post-NST tumor bed biopsies.

VII. To improve identification and selection of patients with breast and possible axillary pCR for future trial planning, routine biomarkers (estrogen receptor [ER], progesterone receptor [PR], HER2 neu, and Ki67) will be collected to allow comparison to image/clinical complete response (CR), and tumor bed biopsies.

OUTLINE:

After completion of neoadjuvant therapy, patients undergo stereotactic biopsy of breast tumor any time prior to breast conserving surgery. Patients then undergo breast conserving surgery as per standard of care. Patients may also undergo postoperative radiation therapy per standard of care or adjuvant therapy at the investigator's discretion.

Primary Outcome Measures :
  1. Proportion of patients with pCR [ Time Frame: Up to 18 months ]
    The proportion of tumor bed biopsies that are negative among those who are shown to have pCR at surgery will be determined. The point estimate and 95% confidence interval will be calculated.


Secondary Outcome Measures :
  1. Improvement of negative predictive value [ Time Frame: Up to 18 months ]
    Analysis will be performed to assess the improvement in the negative predictive value of the trimodality imaging algorithm when the results of tumor bed biopsy are added.

  2. Incidence of adverse events associated with tumor bed biopsy [ Time Frame: Up to 18 months ]
    Descriptive analysis will be performed to determine the frequencies of adverse events associated with tumor bed biopsy.

  3. Number of needle cores performed [ Time Frame: Up to 18 months ]
    Descriptive analysis will be performed to determine the distribution of the number of needle cores performed and the proportion of clips retrieved.

  4. Proportion of clips retrieved [ Time Frame: Up to 18 months ]
    Descriptive analysis will be performed.

  5. Residual cancer burden score [ Time Frame: Up to 18 months ]
    Descriptive analysis will be performed to determine the distribution of residual cancer burden score.

  6. Trimodality imaging algorithm +/- biopsy as a predictor of pCR [ Time Frame: Up to18 months ]
    Analysis will be performed to assess the improvement in the negative predictive value of the trimodality imaging algorithm when the results of tumor bed biopsy are added.

Criteria

Inclusion Criteria:

  • The patient must have signed and dated an Institutional Review Board (IRB)-approved consent form that conforms to federal and institutional guidelines
  • The patient must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Patients must have had ER analysis performed on the primary breast tumor collected prior to neoadjuvant therapy according to current American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guideline recommendations for hormone receptor testing; if negative for ER, assessment of progesterone receptor (PgR) must also be performed according to current ASCO/CAP Guideline Recommendations for hormone receptor testing
  • Patients must have had HER2 testing performed on the primary breast tumor collected prior to neoadjuvant chemotherapy according to the current ASCO/CAP guideline recommendations for human epidermal growth factor receptor 2 testing in breast cancer; patients who have a primary tumor that is HER2-positive, HER2-equivocal, or HER2-negative are eligible
  • Patients must have a biopsy marker placed within the tumor bed with imaging confirmation (preferably mammogram but ultrasound or magnetic resonance imaging [MRI] is acceptable) of marker placement prior to neoadjuvant chemotherapy

  • Patients must be undergoing breast conserving therapy
  • Patient must be able to undergo stereotactic-vacuum-assisted breast biopsy with clip placement after completion of neoadjuvant chemotherapy
