观察甲状腺乳头状癌颈部淋巴结转移的超声诊断价值

To Observe the Value of Ultrasonography in the Diagnosis of Cervical Lymph Node Metastasis of Thyroid Papillary Carcinoma

目的探讨甲状腺乳头状癌颈部淋巴结转移的超声特点和临床诊断价值。方法随机选取2019年2月—2020年7月本院接收的50例甲状腺乳头状癌患者,所有患者均采取超声检查,比较术后病理结果与超声检查结果。结果50例患者术后病理检查结果,颈部转移性淋巴结、非转移性淋巴结分别有95枚与10枚;经超声检查,枚颈部转移性淋巴结与非转移性淋巴结分别有105枚与13枚。内部微钙化、门部回声不均匀和边缘缺损方面,转移淋巴结分别是45.71%、61.90%与63.81%,非转移淋巴结分别是15.38%、30.77%、30.77%,非转移淋巴结比转移性淋巴结低,差异有统计学意义(P<0.05);血流阻力RI和血流收缩期速度方面,非转移性淋巴结比转移性淋巴结低,差异有统计学意义(P<0.05)。经病理检查,50例患者中,单个淋巴结转移与多个淋巴结转移分别有12例与38例;多个淋巴结转移检出率较单个淋巴结转移高,差异有统计学意义(P<0.05)。结论超声在甲状腺乳头状癌颈部淋巴结转移诊断中应用效果明显,该方法对于病情的判断和病灶的显示有利,值得采纳。其能够将病变状况等清楚的显示出来,从而更好的判断疾病,为临床诊治提供数据参考。

Objective To investigate the ultrasonic characteristics and clinical diagnostic value of cervical lymph node metastasis of thyroid papillary carcinoma.Methods 50 patients with thyroid papillary carcinoma received in our hospital from February 2019to July 2020 were randomly selected.All patients were examined by ultrasonography.The postoperative pathological results were compared with those of ultrasonography.Results The results of postoperative pathological examination of 50 patients:there were 95 cervical metastatic lymph nodes and 10 non metastatic lymph nodes respectively.By ultrasonography,there were 105 metastatic lymph nodes and 13 non metastatic lymph nodes in the neck,respectively.In terms of internal microcalcification,uneven echo of portal and marginal defect,the metastatic lymph nodes were 45.71%,61.90% and 63.81% respectively,and the non metastatic lymph nodes were 15.38%,30.77% and 30.77% respectively.The non metastatic lymph nodes were lower than the metastatic lymph nodes(P<0.05).In terms of blood flow resistance RI and systolic velocity,non metastatic lymph nodes were significantly lower than metastatic lymph nodes(P<0.05).Pathological examination showed that there were 12 cases of single lymph node metastasis and 38 cases of multiple lymph node metastasis in 50 patients.The detection rate of multiple lymph node metastasis was higher than that of single lymph node metastasis(P<0.05).Conclusion Ultrasound is effective in the diagnosis of cervical lymph node metastasis of thyroid papillary carcinoma.This method is beneficial to the judgment of the condition and the display of the focus,which is worth adopting.
