乳腺癌前哨淋巴结检出方法研究进展

Progress of sentinel lymph node detection in breast cancer

前哨淋巴结（SLN）是接受乳房淋巴回流的第一群淋巴结，亦是最早发生癌转移的一群淋巴结。其能准确预测腋窝淋巴结（ALN）的转移状况，是乳腺癌诊断与治疗的重要参考因素，已成为早期乳腺癌分期的首选评估方法。对SLN进行快速、准确的术中定位与诊断，对选择手术方式及提高治疗疗效有重大意义。 SLN最佳定位与诊断方法仍在不断研究中，文章就近年来运用于临床上的各种方法进行综述。

Sentinel lymph node （SLN） is the first group of lymph nodes to receive breast lymph nodes and the first group of lymph node metastasis. It can accurately predict the metastatic status of axillary lymph nodes, which is an important reference factor in the diagnosis and treatment of breast cancer. It has become the first choice for early breast cancer staging. The rapid and accurate intraoperative localization and diagnosis of SLN is of great significance for the choice of operation mode and the improvement of therapeutic effect. SLN location and diagnostic methods are still needed to be investigated. This article reviews various methods in clinic recently.
