Brief Summary
The aims of this study is to evaluate 5 year recurrence free survival when omit sentinel lymph node biopsy after neoadjuvant chemotherapy in triple negative or HER-2 positive breast cancer patients when physical examination expected complete remission. And radiological expected Tumor size ≤ 2cm or non-mass enhancement ≤ 4cm.
