Tumor Characteristics Influencing Non-Sentinel Lymph Node Involvement in Clinically Node Negative Patients with Breast Cancer

摘要

PurposeThe negative sentinel lymph node (SLN) biopsy avoids conventional axillary dissection in patients with breast cancer with clinically negative axilla. Despite negative SLN, there is a risk of leaving involved non-SLN behind in the axilla. We investigated the predictive power of tumor characteristics for non-SLN metastasis.
