Performing sentinel lymph node biopsy is associated with a significantly improved survival compared to level I & II axillary lymph node dissection in node negative breast cancer p…

Introduction: The sentinel lymph node (SLN) biopsy has emerged as the standard of care in evaluating the axillary lymph node status in early stage breast cancer patients. It is well known that step sectioning and immunohistochemistry of the SLN allow for a more accurate histopathologic examination. Conversely, it remains to be elucidated whether or not the more accurate SLN staging is associated with improved survival. Therefore, the objective of the present investigation was to evaluate if patients undergoing a SLN biopsy have an improved disease-free and overall survival compared to those undergoing ALND. Meth…
