Ultrasonic Characterization Of Predicted Cervical Lymph Node Metastasis In Papillary Thyroid Carcinoma

Objective:The research analyzed the Ultrasound imaging characteristics using conventional ultrasound(US)combined with contrast-enhanced ultrasound(CEUS)of Papillary thyroid carcinoma(PTC)patients as well as the relevance of Cervical lymph node metastasis(CLNM).And it is purposed to investigate the application value of the effective ultrasonic diagnostic basis for the choice of PTC clinical treatment methods.Methods: 208 TC cases who underwent thyroidectomy and neck lymph node dissection surgery from the Second Xiangya Hospital of Central South University from January 2020 to January 2021 were enrolled in the research.All of them had thyroid US combined with CEUS inspection.And the TI-RADS diagnostic classification were performed according to the 《 2020 Chinese guidelines for ultrasound malignancy risk stratification of thyroid nodules,C-TIRADS 》 and characteristics of ultrasonic nodules.Meanwhile,each patient underwent cervical lymph node dissection and obtained lymph node pathology.All nodules had postoperative pathology,with pathological results in papillary thyroid carcinoma.The relationship between ultrasound characteristics and PTC neck lymph node metastasis was analyzed.Results: Ultrasound image characteristics such as calcification,aspect ratio,edge and contrast agent filling characteristics can not predict CLNM.The thyriod nodule size and the C-TR classification was associated with CLNM(p<0.01).Conclusions: Exploring the nature and risk factors of cervical lymph node metastasis in PTC patients is important to guide cervical lymph node dissection.The thyroid nodule size and high C-TR scores are risk factors for CLNM.It can provide an objective basis for the formulation of clinical precision treatment strategies.
