Axillary Ultrasound Evaluation in Breast Cancer Patients: A Multidisciplinary Viewpoint and Middle Ground
Abstract Over the past decade, there has been a trend toward de-escalation of axillary surgery. Certain patients may now forego axillary lymph node dissection even in the setting of a positive sentinel lymph node biopsy (SLNB), and some patients may not even undergo a SLNB. However, there is wide variability in the imaging approach to assessing axillary lymph nodes in patients with breast cancer. Approaches range from performing axillary US in all patients with newly diagnosed breast cancer to omitting axillary imaging evaluation in all patients. This article provides a multidisciplinary middle ground approach for axillary nodal evaluation. The clinical impact and rationale for appropriate axillary nodal imaging are discussed and an imaging algorithm is proposed.
