Sentinel node biopsy after neoadjuvant treatment in breast cancer: Five-year follow-up of patients with clinically node-negative or node-positive disease before treatment

摘要

Purpose: It is controversial whether sentinel node biopsy (SNB) without axillary dissection (AD) should be performed in cN1/2 breast cancer patients who become cN0 after neoadjuvant treatment, since the false negative rate (FNR) may be unacceptably high. We assessed outcomes to address this issue.
