Radiologic Mapping for Targeted Axillary Dissection: Needle Biopsy to Excision

AJR Am J Roentgenol. 2016 Dec;207(6):1372-1379. doi: 10.2214/AJR.16.16545. Epub 2016 Oct 11.

Abstract

Objective: The purpose of this article is to describe the feasibility and safety of a multidisciplinary approach to imaging-guided axillary staging that facilitates personalized, less invasive surgical management of the axilla through targeted axillary dissection in patients with biopsy-proven nodal metastasis undergoing neoadjuvant chemotherapy.

Conclusion: Axillary nodal status, critical in breast cancer staging, affects prognosis and treatment. As the paradigm shifts toward minimally invasive therapy, a clip marker is placed in the biopsied metastatic node for patients with N1-N2 disease undergoing neoadjuvant chemotherapy to facilitate targeted axillary dissection of the clipped node. This node is typically localized with a radioactive seed at sentinel lymph node dissection to determine whether further axillary surgery is warranted.

Keywords: axillary lymph node; breast; breast cancer; radioactive seed; targeted axillary dissection; ultrasound.
