摘要
目的:分析超声检查血流参数在诊断甲状腺癌颈部淋巴结转移中的效能。方法:选取2021年5月—2023年5月东平县人民医院收治的96例甲状腺癌患者,根据是否有颈部淋巴结转移将其分为未转移组(n=54)与转移组(n=42),所有患者均行彩色多普勒超声检查,对比两组超声影像特征与超声血流参数[收缩期峰值流速(PSV)、阻力指数(RI)、搏动指数(PI)]的差异;另描绘受试者工作特征(ROC)曲线,分析超声血流参数(PSV、RI、PI)诊断甲状腺癌颈部淋巴结转移的效能。结果:转移组的淋巴门占比为11.90%(5/42),低于未转移组的62.96%(34/54);钙化占比为45.24%(19/42),囊性变占比为47.62%(20/42),PSV为(35.58±4.20)cm/s,RI为(0.89±0.14),PI为(2.25±0.71),均高于未转移组的5.56%(3/54)、7.41%(4/54)、(27.89±2.67)cm/s、(0.65±0.06)(1.54±0.46),差异有统计学意义(P <0.05);ROC曲线结果显示,PSV、RI、PI联合诊断甲状腺癌颈部淋巴结转移的曲线下面积(AUC)高于三者单独诊断。结论:超声血流参数能够诊断出甲状腺癌颈部淋巴结转移,具有一定的诊断效能,临床可推广应用。
Objective To analyze the effectiveness of blood flow parameters by color Doppler ultrasonography in diagnosing cervical lymph node metastasis of thyroid cancer.Methods Ninety-six patients with thyroid cancer admitted to Dongping County People's Hospital from May 2021 to May 2023 were selected and divided into non-metastatic group(n=54)and metastatic group(n=42)according to whether they had cervical lymph node metastasis.All patients underwent color Doppler ultrasonography.The ultrasound image characteristics and Doppler parameters[peak systolic velocity(PSV),resistance index(RI)and pulsatility index(PI)]were compared between the two groups.The receiver operating characteristic(ROC)curve was also described,and the efficacy of PSV,RI and PI in the diagnosis of cervical lymph node metastasis of thyroid cancer was analyzed.Results The proportion of lymphatic hilum in metastatic group was 11.90%(5/42),lower than that in non-metastatic group[62.96%(34/54)];calcification was 45.24%(19/42)and cystic change was 47.62%(20/42).PSV was(35.58±4.20)cm/s,RI was(0.89±0.14),PI was(2.25±0.71),It was higher than that in the non-metastatic group[5.56%(3/54),7.41%(4/54),(27.89±2.67)cm/s,(0.65±0.06),(1.54±0.46)],and the difference was statistically significant(P<0.05).ROC curve results showed that the area under the curve(AUC)of PSV,RI and PI combined diagnosis of cervical lymph node metastasis of thyroid cancer was higher than that of PSV,RI and PI alone diagnosis.Conclusion The blood flow parameters measured by color Doppler ultrasonography can diagnose cervical lymph node metastasis of thyroid cancer,which has certain diagnostic efficacy and can be widely applied in clinical practice.
