10余年前出现的乳腺癌前哨淋巴结活检术(sentinelymph node biopsy,SLNB)是一种微创且能高度准确检测腋窝淋巴结转移的方法。该技术发展迅速,对传统腋窝淋巴结清扫术(axillary lymph node dissection,ALND)的理念提出了质疑和挑战。长期以来,因ALND术后出现上肢水肿、疼痛及其他功能障碍等并发症,严重影响了患者的生活质量[1]。通过对前哨淋巴结(sentinel lymph node,SLN)状态的检测和判定,能够 Sentinel lymph node biopsy (SLNB), occurring more than 10 years ago, is a minimally invasive and highly accurate method of detecting axillary lymph node metastases. The rapid development of this technology has challenged the concept of the traditional axillary lymph node dissection (ALND). For a long time, ALND postoperative complications such as upper extremity edema, pain and other disorders have seriously affected the quality of life of patients [1]. By detecting and determining the status of the sentinel lymph node (SLN)
