彩色多普勒超声检查在诊断微小乳腺癌腋下淋巴结转移中的应用

The Application of Color Doppler Ultrasonography for Diagnosing Subaxillary Lymphatic Metastasis in Small Breast Cancer

目的:探讨彩色多普勒超声检查在诊断微小乳腺癌腋下淋巴结转移中的应用。方法:回顾性选取2014年2月至2017年2月确诊治疗的微小乳腺癌患者60例,所有患者均给予二维超声和彩色多普勒超声检查。结果:腋下淋巴结转移的主要超声特征为淋巴结长短径比≤2.0、皮质增厚、内部回声不均匀、钙化、彩色多普勒血流显像(CDFI)血流分级为Ⅱ~Ⅲ级,在诊断腋下淋巴结转移的效能方面,二者联合时明显高于二者单独时(P<0.05),但二者单独时基本相同。结论:微小乳腺癌腋下淋巴结转移与无淋巴结转移在形态、内部回声、钙化、血流等超声特征中存在显著差异,二维超声和彩色多普勒超声检查可诊断其腋下淋巴结转移的发生,二者联合时具有更好的效能。

Objective:To discuss the application of color doppler ultrasonography for diagnosing subaxillary lymphatic metastasis in small breast cancer.Methods:60 patients with small breast cancer were selected from February 2014 to February 2017 in our Hospital,all patients were given two-dimensional ultrasound and color doppler ultrasonography.Results:In this study,the main ultrasonic characteristic of subaxillary lymphatic metastasis were≤2.0 lymphatic length to diameter ratio,cortical thickening,internal echo,calcification and color doppler flow imaging(of a CDFI)class forⅡ~Ⅲblood flow,in diagnosing the efficiency of axillary lymph node metastasis,when they combined were significantly higher than those of the two separate(P<0.05),but when the two separate were basically same.Conclusion:Shape,internal echo,calcification,blood flow and other ultrasonic characteristics have significant differences between subaxillary lymphatic metastasis and no lymphatic metastasis in small breast cancer,two-dimensional ultrasound and color doppler ultrasonography can diagnose the subaxillary lymphatic metastasis,and when they combine will has better efficiency.
