5. Study Description

Brief Summary
This study is a multi-center, prospective, self-controlled study, to evaluate the feasibility of targeted axillary lymph node resection (TAD) guided by tissue marker clip with methylene blue single tracer after neoadjuvant chemotherapy in T1-4N1M0 breast cancer patients. Evaluate the accuracy and false negative rate of TAD, comparing with sentinel lymph node biopsy, and explore a new axillary-preserving mode after neoadjuvant chemotherapy for breast cancer.
