摘要
目的:探讨增强CT结合高频超声对甲状腺乳头状癌(Papillary thyroid carcinoma)颈部淋巴结转移的诊断意义。方法:选取2018年12月~2020年12月本院收治的60例疑似颈部淋巴结转移的甲状腺乳头状癌(PTC)患者,术前进行增强CT和高频超声检查有无颈部淋巴结转移,术后进行病理检查。比较增强CT及高频超声诊断结果与两者结合诊断灵敏度、特异性、准确度及符合率。结果:增强CT诊断颈部淋巴结转移的灵敏度为71.93%,特异性为33.33%,准确度为71.67%。高频超声诊断颈部淋巴结转移的灵敏度为70.18%,特异性为33.33%,准确度为70.00%。增强CT结合高频超声诊断颈部淋巴结转移的灵敏度为92.98%,特异性为66.67%,准确度为90.00%。经术后病理确诊57例颈部淋巴结转移,其中颈中央区34例,颈侧区23例。CT、高频超声对颈中央区和颈侧区转移诊断符合率比较差异无统计学意义(P>0.05);增强CT结合高频超声诊断符合率显著高于单独检查(P<0.05)。结论:明确甲状腺乳头状癌(PTC)患者是否有颈部淋巴结转移对临床治疗及预后判断具有重要价值;增强CT结合高频超声进行诊断可取长补短,提高诊断准确率、灵敏度及特异性,为患者是否需要清扫淋巴结提供一定参考依据。
Objective:To investigate the diagnostic significance of CT combined with high-frequency ultrasound in cervical lymph node metastasis of papillary thyroid carcinoma.Methods:60 papillary thyroid carcinoma patients with suspected cervical lymph node metastasis from December 2018 to December 2020were enrolled;CT and high-frequency ultrasound were performed before operation,and pathological examination was performed after operation.Then the diagnostic sensitivity,specificity,accuracy and coincidence rate of single examination and combined examination were compared.Results:The sensitivity,specificity and accuracy of CT in the diagnosis of cervical lymph node metastasis were 71.93%,33.33%and 71.67%,respectively.The sensitivity,specificity and accuracy of high frequency ultrasound in the diagnosis of cervical lymph node metastasis were 70.18%,33.33%and 70.00%,respectively.The sensitivity,specificity and accuracy of CT combined with high frequency ultrasound in the diagnosis of cervical lymph node metastasis were 92.98%,66.67%and 90.00%.Among 60 patients with suspected cervical lymph node metastasis,57 cases were confirmed by postoperative pathology,including 34 cases of central cervical lymph metastases and 23 cases of lateral cervical region lymph metastases.The coincidence rates of CT and high-frequency ultrasound in the diagnosis of cervical central and lateral cervical metastases had no significant difference(P>0.05).The coincidence rate of CT combined with high-frequency ultrasound for cervical lymph node metastasis was significantly higher than that of single examination(P<0.05).Conclusion:The diagnosis of cervical lymph node metastasis is of great value for the clinical treatment and prognosis evaluation of patients with thyroid papillary carcinoma,while CT combined with high-frequency ultrasound examinations can improve diagnostic accuracy,sensitivity and specificity,and provide a reference for lymph node dissection.
