Abstract:
Objective To evaluate the correlation between sonographic features of papillary thyroid microcarcinoma(PTMC) and cervical lymph node metastasis.Methods Preoperative sonographic features of 379 papillary thyroid microcarcinoma in 341 patients were retrospectively reviewed,and were divided into two groups,lymph node metastasis and lymph node non-metastasis according to pathology.Univariate and multivariate analyses were performed to analyze the sonographic features relevant to lymph node metastasis.Results Univariate analysis revealed that unclear border,microcalcification and multifocal PTMC were statistically significant(all P ＜0.05).Multivariate analysis revealed that microcalcification and multifocal PTMC were statistically significant (both P ＜0.05).Conclusions Microcalcification and multifocal PTMC are closely relevant to cervical lymph node metastasis.
