摘　　要：Sentinel lymph node biopsy （SLNB） is a new surgical technique for local axillary lymph nodes （ALNs） of breast cancer. Large-scale clinical trials have confirmed that undergoing SLNB and ALN dissection （ALND） showed no significant difference for sentinel lymph node （SLN）-negative patients in terms of disease-free survival, overall survival and recurrence-free survival. However, false-negative results are still the main concern of physicians as well as patients who undergo SLNB instead of ALND. The American Society of Breast Surgeons established a task force to suggest acceptable standards for SLNB. In 2000, the task force recommended that the identification rate for SLNB be 85% or higher and the false-negative rate be 5% or lower. This review focuses on clinical factors （tumor volume, multifocal/multi-center cancers, neoadjuvant chemotherapy and skip metastasis）, tracer techniques and pathological factors affecting SLNB and explores methods for reducing the false-negative rate.Sentinel lymph node biopsy （SLNB） is a new surgical technique for local axillary lymph nodes （ALNs） of breast cancer.
