乳腺癌引流区淋巴结转移与否为疾病的 TNM 分期、手术方式的选择、术后辅助治疗及判断预后提供重要依据，淋巴结转移越广泛，预后越差。随着超声医学技术的发展，超声造影等新技术的应用为疾病定性诊断提供了新的诊断思路。超声在早期乳腺癌前哨淋巴结（ SN）定性诊断中的临床应用价值越来越得到重视，确认原发癌有无 SN转移对治疗方案的选择及判断预后有重要意义。该文就乳腺癌SN的定义、意义及超声检查技术在早期乳腺癌SN定性诊断中的应用予以综述。

Determining whether the draining sentinel node ( SN) ,metastasis in breast cancer provides an important basis for the assessment of TNM stage,the choice of surgical approach,the adjuvant therapy of post-operative and the estimation of prognosis.Accordingly,it indicates a mournful result when abundant lymph nodes are infected.more extensive SN metastasis,the worse the prognosis.With the development of technology of ultrasound in medicine ,contrast-enhanced ultrasonography have provided a new diagnostic approach in the qualitative diagnosis of disease .The technology of ultrasonography is more and more get attention in early breast cancer SN qualitative diagnosis clinically .It has important significance to confirm whether the exist-ence of primary cancer's SN metastases on the choice of treatment and prognosis .Here,we will summarize the definition and the significance of SN in breast cancer ,but also the application of ultrasound technology in the early diagnosis of SN in breast cancer.
