Objectives

Principal

The aim of this study was to provide sufficient evidence to validate SLNB for pT3 BC, initially cN0 usN0, in case of up-front surgery. These cases can correspond to cT3 BC or cT2 BC with pT3 tumor on final pathology. The evidence analyzed on a large cohort of patients, distinguishing four size categories, was as follows: Comparison, according to categories sizes, of false negative (FN), negative predictive values (NPV), accuracy, axillary lymph node involvement rates, and evaluation of possible completion ALND omission rates according to categories sizes.
