From cN2 to ypN0: Nodal Downstaging After Neoadjuvant Treatment in Breast Cancer-A Retrospective Cohort Study from a Tertiary Cancer Center

Background/Objectives: In patients with clinically node-positive breast cancer, axillary response to neoadjuvant systemic treatment is heterogeneous and might depend on tumor biology. In patients with cN2 disease, the identification of factors linked to nodal response could improve risk stratification and contribute to the development of individualized post-neoadjuvant axillary management strategies.
