Prospective Study on the Clinical Prognosis of Bilateral Central Lymph Node Dissection in the Patients With Unilateral Thyroid Papillary Carcinoma
This study recruit the patients with unilateral papillary thyroid cancer before operation,the
 patients agree to enter the test,and divided into experimental and control group.experimental
 group patients receive the surgery including unilateral thyroid lobectomy and bilateral
 central lymph node dissection.and control group receive the surgery including unilateral
 thyroid lobectomy and unilateral central lymph node dissection.last the investigators compare
 numbers of patient with tumor recurrence and metastasis rate of 5 years,numbers of metastatic
 lymph node,and numbers of participants with adverse events related to treatment between two
 groups in order to evaluate the significance of bilateral lymph node dissection.
