Lymphovascular Invasion Enhances the Prediction of Non-Sentinel Node Metastases in Breast Cancer Patients with Positive Sentinel Nodes

Background:Fifty percent of patients with sentinel lymph node (SLN) metastases have no metastatic disease in non-SLNs on axillary lymph node dissection (ALND). The goal of this study is to determine which patients have metastatic disease limited to the SLN, and, therefore, may not require completion ALND.
