随着对乳腺癌生物学特性的认识不断深入以及医疗技术的不断发展,乳腺癌全身辅助治疗的方式越来越多样、疗效越来越显著,能有效控制局部复发与远处转移~([1])。因此,近年来有作者提出:基于全身辅助治疗作用的提升与强化,乳腺癌手术治疗的理念是否应作出改变。在保证疾病预后的前提下,能否进一步缩小手术范围,降低手术创伤~([2-4])。乳腺癌的保乳手术与腋窝淋巴结清扫术,成为关注热点。其中,一系列临床研究都关注于前哨淋 With the deepening of the understanding of the biological characteristics of breast cancer and the continuous development of medical technology, the way of systemic adjuvant treatment of breast cancer more and more diverse, more and more significant effect, can effectively control the local recurrence and distant metastasis ~ ([1 ]). Therefore, in recent years, some authors put forward the idea of ​​whether the concept of surgical treatment of breast cancer should be changed based on the promotion and strengthening of systemic adjuvant therapy. Under the premise of ensuring the prognosis of the disease, can further narrow the scope of surgery and reduce surgical trauma ~ ([2-4]). Breast-conserving surgery and axillary lymph node dissection, becoming a hot spot. Among them, a series of clinical studies have focused on the sentinel
