Management For The CN₀ Patient With Differentiated Thyroid Carcinoma And Influential Factor Analysis

Objective To evaluate the optional management for the cN₀ patient with differentiated thyroid carcinoma and influential factor analysis Method Retrospective analysis of 61cases of cN₀ with differentiated thyroid carcinoma between 2000 and 2005 . Lobectomy for tumor side plus isthmusectomy plus subtotal lobectomy for another side and Lobectomy for tumor side plus isthmusectomy was performed in 53 cases , total thyroidectomy was performed in 5 cases , isthmusectomy plus subtotal lobectomy . Subtotal lobectomy for both sides plus isthmusectomy was performed in 3 cases. All of the cases were performed with neck dissection of the region VI .61 cases were divided into groups by age and tumor size ,according to the staging of TNM of UICC 2002, and discussed the influential factors of lymph node metastasis of the region VI.Result The 5 and 3 years survival rates were 100%. The lateral neck lymph nodes metastasis was appeared in lcase and elective neck dissection was performed . 1 case lost flup. Other cases have lived without tumor. 4 of 5 cases operated with total thyroidectomy suffered hypopthyroidism in 4-7 days , but the hypothyroidism symptom disappeared after 4-7 days. There was no hypothyroidism and hypoperthyroidism in other cases . No recurrent nerve paralysis occurred except 3 patients who had recurrent nerve paralysis preoperative .The incidence of metastatic disease in the lymph nodes...
