彩色多普勒超声与超声弹性成像在乳腺癌淋巴转移诊断中的应用

Application of color Doppler ultrasound and ultrasound elastography in diagnosis of lymphatic metastasis of breast cancer

目的探讨彩色多普勒超声和超声弹性成像技术对乳腺癌淋巴转移的诊断价值。方法选择2017年1月～2018年3月湖州市中心医院确诊的乳腺癌患者90例,术前均行彩色多普勒超声和超声弹性成像检查,术后进行组织学病理学检查。结果 90例患者中,淋巴转移患者49例,无淋巴转移患者41例。淋巴转移患者彩色多普勒超声血流等级和超声弹性成像评分显著高于无淋巴转移患者,差异有统计学意义(P <0.05)。超声弹性成像的敏感度、特异性均显著高于彩色多普勒超声,差异有统计学意义(P <0.05)。结论乳腺癌淋巴转移患者与无淋巴转移患者的彩色多普勒超声和超声弹性成像不同,超声弹性成像对于乳腺癌淋巴转移均有较高的敏感度和特异性,值得临床推广应用。

Objective To investigate the application of color doppler ultrasound and ultrasound elastography in diagnosis of lymphatic metastasis of breast cancer. Methods From January 2017 to March 2018, in Huzhou Central Hospital, 90 patients with breast cancer were selected, they were detected by color Doppler ultrasound and ultrasound elasticity imaging on preoperative and histological pathology examination postoperative. Results Among 90 patients, 49 patients were lymphatic metastasis, and 41 patients without lymphatie metastasis. The color Doppler flow grade and score of ultrasound elasticity imaging in the patients with lymphatic metastasis were significantly higher than the patients without lymphatic metastasis, the differences were statistically significant （P 〈 0.05）. The sensitivity and specificity of color doppler ultrasound combined with ultrasonic elastography were significantly higher than the color Doppler ultrasound and ultrasonic elastography, the differences were statistically significant （P 〈 0.05）. Conclusion Color Doppler ultrasound and ultrasound elastography, were not the same for patients with lymphatic metastasis of breast cancer and non-metastic patients and the ultrasonic elastography has high sensitivity and specificity for lymphatic metastasis of breast cancer. It is worthy of clinical popularization and application.
