Abstract:
Objective To investigate the relationship between ultrasonographic features of papillary thy-roid carcinoma(PTC)and lateral cervical lymph node metastasis (LCLNM).Methods A total of 449 eligible ca-ses with 633 PTC nodules was selected and divided into two groups:LCLNM group included 135 nodules(91 pa-tients);Without metastatic groups included 498 nodules(135 patients).Ultrasonographic features of PTC nodules and the relationship with LCLNM were analyzed by χ2 test and logistic regression analysis .Results In univariate analysis,the significant factors were male,age<45yrs,multifocal,maximal diameter(d>1 cm),multi-microcal-cificaltion(d<2 mm),mixed flow,wider than tall,CCLNM,extrathyroid extension,located in upper(P<0.05 or P<0.017).Multivariate analysis showed that multi -microcalcificaltion(d<2 mm),wider than tall,CCLNM,ex-trathyroid extension,located in upper pole were predictive factors of LCLNM (P<0.005,OR=1.626,2.644, 0.479,2.579).Conclusion High-frequency ultrasound can accurately describe the sonographic appearance of thyroid nodules;it can be used to remind the risk of LCLNM before operation ,and will be informative for the treat-ment of surgery .
