摘要
目的 探讨超声弹性成像在左锁骨上淋巴结肿大良恶性鉴别中的应用价值.方法 对45例左锁骨上淋巴结肿大的患者,进行超声弹性成像技术检查,采用四分法对肿大淋巴结进行评分,然后根据弹性评分进行良恶性的判别,最后对肿大淋巴结取组织进行病理活组织检证查明超声弹性成像技术判断的准确性.结果 病理检查结果显示45例患者中15例为良性增生,30例为恶性.通过分析肿大淋巴结弹性评分绘制ROC曲线,弹性评分1分、2分判定为良性,3分、4分判定为恶性;超声弹性评分判断左锁骨上淋巴结肿大良恶性的敏感度为90.3％、特异度为85.7、准确率为88.9％;ROC曲线线下面积为0.913,用超声弹性成像判断肿大左锁骨上淋巴结良恶性差异有统计学意义（P＜0.01）.结论 超声弹性成像技术对左锁骨上淋巴结肿大的良恶性判定具有重要的价值,对临床诊断左锁骨上淋巴结转移癌具有显著的诊断意义,可先于组织病理检查用于淋巴结转移癌的诊断.
Objective To explore the effect of ultrasound elastography on the diagnosis of benign and malignant left supraclavicular lymph nodes. Methods A total of 45 cases with enlarged left supraclavicular lymph nodes were examined by ultrasound elastography. The score of every case was made base on the ultrasound elastography images. The benign or malignant lymph nodes were judged according to the scores and then the pathological examination of lymph nodes evaluated the right or wrong of the judgments. Results The pathological examination showed 15 case with benign left supraelavicular lymph nodes and 30 cases with malignant left supraclavicular lymph nodes. The ROC curve made according to the scores indicated the benign lymph nodes is 1 point or 2 points and the malignant lymph nodes is 3 points or 4 points; the sensitivity, specificity and accuracy were 90.3%, 88.9%, 88.9%.The area under the ROC curve is 0.913; the ultrasound elastography was significant in distinguishing the benign or malignant left supraclavicular lymph nodes （ P〈0.01 ） . Conclusions Ultrasound elastography can be an important technique to estimate the benign and malignant left supraclavicular lymph nodes and should be used to identify the benign and malignant left supraclavicular lymph nodes before the pathological examination.
