  • Clinical Study of Central Lymph Node Dissection in Patients with cN0 Papillary Thyroid Carcinoma

    ObjectiveTo investigate the value of central lymph node dissection in patients with cN0 papillary thyroid carcinoma. MethodThe clinical data of 128 patients with cN0 papillary thyroid carcinoma who had been performed central lymph node dissection during their hospitalization from December 2010 to July 2012 in Chinese PLA General Hospital were analyzed retrospectively. ResultsThe central neck lymph node metastasis rate was 35.94%(46/128) in 128 patients with cN0 papillary thyroid carcinoma, which in the patients with aged less than 45 years, with the tumor diameter larger than 1 cm, and with capsule or extrathyroidal invasion were significantly higher than those in the patients with aged larger than 45 years, with the tumor diameter less than 1 cm, and without capsule or extrathyroidal invasion (P < 0.05). After the operation, there were 22(17.19%) patients with temporary hypoparathyroidism as well as 3(2.34%) patients with temporary recurrent laryngeal nerve injury. However, no permanent recurrent laryngeal nerve injury and permanent hypoparathyroidism occurred. During the 14-32 months follow-up with an average 23.4 months, 2 cases of lateral neck lymph node metastases were observed. ConclusionAs an essential, effective, and safe operation to the patients with cN0 papillary thyroid carcinoma, central lymph node dissection should be performed by experienced hands.
