颈部淋巴结转移甲状腺乳头状癌的超声特征分析

Analysis of ultrasound features of cervical lymph node metastasis thyroid papillary carcinoma

目的:探讨颈部淋巴结转移甲状腺乳头状癌的超声特征。方法:选取2015年1月至2017年5月收治的100例颈部淋巴结转移甲状腺乳头状癌患者,将其纳入到观察组;选取同期100例单一甲状腺乳头状癌患者作为对照组;对两组患者的超声诊断效果与影像特征进行分析。结果:超声诊断颈部淋巴结转移甲状腺乳头状癌的准确率与病理学诊断差异无统计学意义(P>0.05)。观察组与对照组患者相比,两组低回声及边界清晰比较差异无统计学意义(P>0.05),而在囊性变,晕环,微钙化及淋巴门指标比较,两组差异具有统计学意义(P<0.05)。两组患者收缩期峰值血流速度(peak systolic velocity,PSV)及阻力指数(resistance index,RI)对比,差异均具有统计学意义(P<0.05)。结论:利用超声诊断在判断甲状腺乳头状癌患者是否存在颈部淋巴结转移的现象上具有较高的准确率。

Objective： To investigate the ultrasound features of cervical lymph node metastasis thyroid papillary carcinoma. Methods： 100 cases of patients with cervical lymph node metastasis thyroid papillary carcinoma in our hospital from January 2015 to May 2017 were selected as research group, and 100 patients with single thyroid papillary carcinoma in the same period were selected as control group. The ultrasound diagnosis effect and image features of the patients were analyzed between the two groups. Results： There was no significant difference of accuracy rate between ultrasonic diagnosis and pathological diagnosis for cervical lymph node metastasis thyroid papillary carcinoma （ P 〈0.05 ）. The difference was not statistically significant in low echo and clear border between the two groups （ P 〉0.05 ）. There were significant differences of the cystic lesions, halo ring, punctate calcification and lymph node index in the two groups （ P 〈 0.05 ）. There were significant differences of peak systolic velocity （PSV） and resistance index （RI） in the two groups（ P 〈 0.05 ）. Conclusion：The ultrasonic diagnosis has a higher accuracy in determining whether there is a cervical lymph node metastasis in thyroid papillary carcinoma.
