Breast Cancer: Axillary Conservation After Neoadjuvant Chemotherapy in Micro Metastatic Sentinel Lymph Nodes.

Summary

Italian multicentric non inferiority clinical study to verify whether the omission of axillary lymph node intervention in patients with SLN (Sentinel Lymph Nodes) ypN1mi after NAC (Neo Adiuvant Chemotherapy) does not lead to a significant deterioration in survival or in the risk of regional or distant recurrence, compared to patients with negative SLN (SLN ypN0) after NAC ,where the omission of axillary treatment is currently the standard treatment.
