Could axillary clearance be avoided in clinically node-negative breast cancer patients with positive nodes diagnosed by ultrasound guided biopsy in the post-ACOSOG Z0011 era?
<h4>Background and objectives</h4>The role of ultrasound (US) guided biopsy in selecting patients for an upfront lymph node dissection (ALND) has been controversial following the publication of the American College of Surgeons (ACOSOG) Z0011 data. The purpose of this study was to investi...

<h4>Background and objectives</h4>The role of ultrasound (US) guided biopsy in selecting patients for an upfront lymph node dissection (ALND) has been controversial following the publication of the American College of Surgeons (ACOSOG) Z0011 data.
