Axillary Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy in Patients With Initial cN1 Breast Cancer

Recruiting now

Conditions studied: Sentinel Lymph Node Biopsy

In brief

SLNB has been recommended by domestic and foreign guidelines for patients with initial cN1 and NAC descending to ycN0. However, the best technical path is still not very clear at present, and the long-term tumor safety data is still insufficient. Therefore, it is necessary to further explore the optimal technical pathway and long-term tumor safety for SLNB in patients with initial cN1 and NAC downgrading to ycN0 in the real world.This study will evaluate the optimized technical pathway and long-term tumor safety of SLNB in patients with initial cN1 and NAC downgrading to ycN0 in real-world studies.
