Objective To investigate the effect of calcification on the ultrasound-guided radiofrequency ablation(RFA)of papillary thyroid carcinoma(PTC).Methods We retrospectively analyzed the preoperative and follow-up data of 164 patients(182 nodules)with PTC treated by percutaneous ultrasound-guided RFA in the First Medical Center of Chinese PLA General Hospital from January 1,2018 to December 31,2021.The tumor status 12 months after RFA was taken as the endpoint event.The univariate Logistic regression analysis was employed to predict the influencing factors of incomplete ablation.The factors were then included in the multivariate Logistic regression analysis for prediction of the independent risk factors of incomplete ablation.Results The maximum nodule diameter(OR=1.16,95%CI=1.04-1.29,P=0.009)and calcification ratio >2/3(OR=19.27,95%CI=4.02-92.28,P<0.001)were the factors influencing the disappearance of lesion 12 months after RFA.Conclusions PTC with calcification can be treated with ultrasound-guided RFA.In the case of calcification ratio ≤ 2/3,this therapy demonstrates the effect equivalent to that of no calcification.
