Prospective Evaluation of Targeted Axillary Dissection (TAD)

Summary

The purpose of this research is to evaluate how to manage the axillary lymph nodes in patients with breast cancer. The investigators will determine if a sampling of the lymph nodes under the arm will give the information necessary to determine if fewer lymph nodes can be removed.

Eligibility

Inclusion Criteria:

* Women or men greater than or equal to 18 years.
* Histologically confirmed invasive adenocarcinoma of the breast.
* Clinical T0-4 N2-3 M0 at diagnosis (American Joint Committee on Cancer, 7th Edition)

  * Assessment for cN2 disease will be performed by clinical exam and imaging. Patients should have pathologic level 1 and/or 2 axillary lymph nodes which are fixed/matted on physical exam.
  * Cross-sectional imaging will be used to identify advanced nodal disease involving the axilla, infraclavicular, supraclavicular, and internal mammary regions, cN3 disease.
* Patients must have biopsy proven involvement of the axillary lymph nodes.
* Receipt of standard multiagent chemotherapy +/- targeted therapy based on tumor subtype.
* Candidate for surgical management of breast cancer.
* Ability to understand and willingness to sign a written informed consent document.
