乳腺癌前哨淋巴结活检的研究进展

目的总结乳腺癌前哨淋巴结活检（SLNB）的研究现状和进展。方法复习近年来国内外的相关文献,对乳腺癌SLNB的概念、适应证、活检技术、提高检出准确率的方法、病理学检查方法、转移灶类型、临床应用等进行综述。结果 SLNB的适应证在不断扩大。示踪剂、影像学检查和病理学检查技术的发展有助于对乳腺癌前哨淋巴结（SLN）状态的评估。乳腺癌SLNB的操作方法还没有统一的标准,对其能否指导选择性的腋窝淋巴结清扫的争议较大,且SLNB的SLN检出率及假阴性率变化范围较大。结论 SLNB已成为乳腺癌外科治疗的重要辅助手段,但其操作尚需进一步规范,其临床应用范围还需要大量前瞻性、多中心的随机试验进一步论证。

Research Progress of Sentinel Lymph Node Biopsy in Breast Cancer

Objective To summarize the current situation and progress of sentinel lymph node biopsy （SLNB） in breast cancer. Methods Domestic and foreign documents related SLNB in breast cancer in recent years were collected to summaize some problems about the definition, indications, biopsy techniques, improvement methods of the detection rate, the pathological examinations of sentinel lymph node （SLN）, the types of metastasis, clinical applications of SLNB technology in breast cancer, and so on. Results The indications of SLNB were expanding. The development of the tracer, imaging examination, and pathological detection technology contributed to the status assessment of SLN in breast cancer. The operation method of SLNB in breast cancer had no uniform standards yet. There were many arguments on whether SLNB can guide axillary lymph node dissection, and the detection rate and the false negative rate of it varied widely. Conclusions SLNB technology has became an important method in the surgical therapy of breast cancer, but the operation still needs to be further standardized. The clinical application of SLNB also needs a lot of prospective multicenter randomized experiments for further demonstration.
