Correlation analysis on central lymph node metastasis in 276 patients with cN0 papillary thyroid carcinoma

To explore the relationship between sex, age, capsule invasion, tumor size, tumor location, number and central lymph node metastasis. Correlation analysis was conducted on clinical data of 276 patients with cN0 papillary thyroid carcinoma who underwent central lymph node dissection. There was significant difference between patients less than 45 years old and greater than or equal 45 years old (P0.5cm of tumor size, less than 45 years old and the present of capsule invasion were high risk factors of central lymph node metastasis, so we strongly recommend performing central lymph node dissection in synchronization.
