Correlation Research Between Preoperative Ultrasonographic Features And Postoperative Recurrence Of Papillary Thyroid Carcinoma

Objective:To assess the risk of recurrence in patients with papillary thyroid carcinoma by investigating which preoperative ultrasound features are associated risk factors for recurrence.Methods:A total of 146 patients with thyroid papillary carcinoma confirmed by postoperative pathology during total thyroidectomy in China-japan Friendship Hospital of Jilin University in 2015 were selected and divided into recurrence group(n=35)and non-recurrence group(n=111)to study their preoperative ultrasound report examination,the presence of thyroiditis,tumor location,the maximum diameter of the primary tumor,tumor number,the presence of focal strong echogenicity within the lesion,the presence of abnormal lymph nodes,the presence of ultrasound imaging manifestations of thyroid invasion,independent sample T test or rank sum test were used for measurement data,χ2 test was used for rank data,and multivariate Logistic analysis was performed for indicators that were significant for univariate analysis.Then ROC curve was used to analyze the diagnostic efficiency of meaningful indicators,and finally kappa test was used to analyze the consistency of ultrasound results and pathological results.Results:There were significant differences in maximum diameter of the primary tumor,and thyroid gland outward invasion between the recurrent and non-recurrent papillary thyroid carcinoma groups(P < 0.05),the recurrence risk increased 1.099 times for every 1mm increase in nodule diameter,and the combined index of these two influencing factors had better diagnostic efficacy,with a specificity of 0.874;In addition,ultrasonic examination and pathological diagnosis have good consistency in the number of papillary thyroid carcinoma tumors,moderate consistency on lymph node metastasis,and excellent consistency on the presence or absence of thyroid invasion.Conclusions:The maximum diameter of the primary tumor,and thyroid gland outward invasion can be used as non-invasive indicators to evaluate the risk of recurrence of thyroid papillary carcinoma by ultrasonic examination.moreover,the combined indicators of these two influencing factors had better diagnostic efficacy.In addition,the number of tumors and the presence of thyroid invasion showed good consistency in ultrasonic and pathological diagnosis.
