Abstract:
Objective To explore the best operation method in the patients with papillary thyroid microcarcinoma.Methods A total of 139 patients with papillary thjroid microcarcinoma were treated at our institute between Jan.2000 and Jan.2010.The data on the clinicopathological characteristics of patients and treatment were collected.Results The mean tumor size was (0.45 ± 0.24) cm.Of the 139 patients,30.2％ had multifocal tumors,19.4％ had bilateral tumors,42.4％ neck lymph node metastases.The number of eases of lymph node metastasis in level Ⅵ,Ⅱa,Ⅲ and Ⅳ was 58(41.7％),3(2.2％),10(7.9％),5(3.6％),respectively.Only one had lymph node metastasis in Level Ⅲ Microscopic extrathyroid extension was associated with neck lymph node metastases in papillary thyroid microcareinoma patients (x2 =38.39,P ＜0.001).No one developed permanent hypoparathyroidism.The median follow-up time was 103 (range,30-154) months,and local recurrence in the thyoid was diagnosed in 2 patients who underwent hemi-or subtotal thyroidectomy.Follow-up of 10 years was done in 16 cases,and the survival rate of 139 patients for 10-year was 100％.Conclusions It suggested that patients with papillary thyroid microcarcinoma has uniform clinicopathologic characteristics and the pattern of lymph node metastasis from those with papillary thyroid carcinoma.Total thyroidectomy plus level Ⅵ dissection is the optimal surgical treatment of papillary thyroid microcarcinoma.
