Abstract:
Objective To explore the sonographic features and clinical factors associated with skip metastasis in papillary thyroid carcinoma (PTC).Methods We reviewed 276 PTC cases pathologically confirmed after operation in our hospital,analyzing the ultrasonographic features and clinical characteristics of primary site and risk factors of skip metastasis.Results The rate of skip metastasis was 16.6％,and level Ⅱ or level Ⅲ were the most common area.In univariate analysis,skip metastasis was associated with tumor location,tumor maximum size,and calcification.Multivariate analysis showed the primary tumor location in the upper portion,tumor size ≤ 10 mm,and microcalcification were independent predictive factors for skip metastasis.Conclusions In papillary thyroid carcinoma,skip metastases rate is high when primary tumor location in the upper portion,tumor size ≤ 10 mm,and there is microcalcification.
