Abstract:
Objective: To investigate the relationship of ultrasonographic findings and cervical lymph node metastasis of papillary thyroid carcinoma (PTC). Methods Clinical and ultrasonographic data of 145 PTC patients were collected, including 60 cases with and 85 cases without cervical lymph node metastasis. The general data (age, sex) and ultrasonographic features (number of lesions, maximum diameter, margin, aspect ratio, invasion of capsule, internal echo, microcalcification, internal blood supply) were retrospectively analyzed. Logistic regression analysis was used to identify independent risk factors for cervical lymph node metastasis in PTC patients. Results: Univariate analysis showed that there were significant differences in age, maximum diameter of tumors, capsular invasion and internal blood supply between PTC patients with cervical lymph node metastasis and those without metastasis (all P<0.01). Logistic regression analysis showed that age ≤50 years old, abundant internal blood supply and invasion of thyroid capsule were independent risk factors for PTC cervical lymph node metastasis (all P<0.05). Conclusion: Patient's age, capsular invasion and internal blood supply of lesions are associated with cervical lymph node metastasis of PTC.
