[Analysis of lymph node jump metastasis in papillary thyroid carcinoma].

Objective: To summarize the metastatic feature of lateral neck lymph node metastasis in papillary thyroid carcinoma. Method: Clinical and pathological data were collected from 301 patients who were first diagnosed as PTC in our hospital. These patients were divided into positive and negative status of lateral cervical lymph nodes and lymph node jump metastasis. Chi-square test and Logistic regression analysis were used to evaluate the relationship between lateral cervical lymph node status and clinicopathology. Result: Tumor size over 2cm, Unilateral thyroid gland contains multiple foci,multiple foci, capsular invasion, ultrasound feature of PTC,the main foci located in the isthmus and the pole of gland, trachea/parathyroid lymph nodes positive were associated with the lymph node jump metastasis in papillary thyroid( P <0.05). Conclusion: Multiple foci in single gland, multifocal foci, calcification and the primary tumor involving the superior pole and middle of the thyroid gland are independent influencing factors for skip lateral lymph node metastasis in PTC( P <0.05).
