Long-term survival in patients with node-positive breast cancer who undergo sentinel lymph node biopsy alone after neoadjuvant chemotherapy: meta-analysis.

Patients who are initially node-positive and who achieve a complete clinical/radiological axillary response after NACT with a subsequent negative SLNB have high rates of DFS and OS after 5 years. Patients with residual disease have significantly reduced DFS and further axillary treatment may still be warranted.
