摘要
目的探讨超声弹性应变率在乳腺癌腋窝淋巴结良恶性的诊断价值。方法回顾性分析已获得病理组织学诊断的89例乳腺癌患者118个腋窝淋巴结的弹性应变率,比较转移性淋巴结与反应性增生淋巴结的弹性应变率,并绘制受试者工作特征曲线(ROC)。结果 118个腋窝淋巴结转移性淋巴结54个,反应性增生64个,超声弹性应变率在乳腺癌腋窝淋巴结良恶性中的诊断的敏感度为90.7%,特异度为87.5%,准确度为90.6%。ROC曲线分析最合适的诊断临界点为2.07。结论超声弹性应变率是一种鉴别转移性淋巴结与反应性增生的淋巴结的有效方法 。
Objective To investigate the ultrasonic elastic strain rate of axillary lymph node benign and malignant diagnosis. Methods Retrospective analysis of 89 pathologically diagnosed breast cancer patients with 118 axillary lymph node elastic strain rate. Ultrasonic elastic strain rate of reactive hyperplasia and metastatic lymph nodes were compared, and ROC curve was drawn. Results In 118 axillary lymph nodes, 54 was metastatic lymph nodes, 64 was reactive hyperplasia. Sensitivity of ultrasonic elastic strain rate of axillary lymph node in breast cancer diagnosis of benign and malignant was 90.7%, specificity was 87.5%, and accuracy was 90.6%. By ROC curve analysis to obtain the most appropriate diagnostic threshold of 2.07. Conclusion Ultrasonic elastic strain rate is a method for identifying metastatic lymph nodes with reactive hyperplasia effective way.
