Does the Number of Harvested Sentinel Lymph Nodes Matter in Breast Cancer Patients with Limited Nodal Burden? A Descriptive Cohort Study

Background/Objectives: In breast cancer patients with limited nodal burden, sentinel lymph node biopsy (SLNB) alone, without axillary lymph node dissection (ALND), has shown non-inferior survival. However, it remains unclear how many SLNs should be harvested. We aimed to determine if the number of harvested SLNs and the use of a single agent for SLNB localisation affect the detection of residual metastatic nodes. We also described the oncological outcome of SLNB alone as an exploratory clinical outcome.
