Abstract

Prophylactic central neck dissection in clinically node-negative patients remains controversial. The aim of this multicenter retrospective study was to determine the rate of metastases in the central neck in clinically node-negative differentiated thyroid cancer patients, to examine the morbidity, and to assess the risk of regional recurrence in patients treated with total thyroidectomy with concomitant bilateral or ipsilateral central neck dissection compared with those undergoing total thyroidectomy alone. 258 consecutive clinically node-negative patients were divided into three groups according to the procedures performed: total thyroidectomy only (group A), total thyroidectomy with concomitant ipsilateral central neck dissection (group B), and total thyroidectomy combined with bilateral central neck dissection (group C). Mean operative time and postoperative stay were shorter in Group A (p < 0.01). The incidence of postoperative transient hypoparathyroidism was lower in Group A (p = 0.03), whereas no differences in the incidence of permanent hypoparathyroidism and nerve palsy were present. Postoperative radioactive iodine administration was higher in group B and particularly C (p = 0.03) compared with group A. There were no statistically significant differences in terms of regional recurrence. Differentiated thyroid cancer has a high rate of central lymph node metastasis even in clinically node-negative patients; in the present study there was no statistically significant difference in the rates of locoregional recurrence between the three modalities of treatment. Total thyroidectomy appears to be an adequate treatment for clinically node-negative differentiated thyroid cancer. Prophylactic central neck dissection might be considered for differentiated thyroid cancer patients with large tumor size or extrathyroidal extension.
