中央区淋巴结清扫在临床颈淋巴结阴性分化型甲状腺癌手术中的应用

The clinical application of central lymph node dissection in differentiation thyroid carcinoma with negative neck lymph node

目的:探讨中央区淋巴结清扫在临床颈淋巴结阴性(cN0期)分化型甲状腺癌(differentiated thyroid carcinoma,DTC)患者手术中的应用价值。方法:对36例(39侧)cN0期DTC患者进行中央区淋巴结清扫,观察术后近远期的临床疗效。结果:中央区淋巴结阳性率41.03%(16/39)。36例中有1例暂时性声音嘶哑,无永久性低钙抽搐等并发症发生。随访1～6年有3例Ⅵ区淋巴结阳性患者术后颈侧区复发再次行颈侧区淋巴结清扫术。结论:cN0期DTC中央区淋巴结转移常见,中央区淋巴结清扫是安全可行的,应常规清扫。

Objective：To investigate the clinical application of central lymph node dissection in differentiation thyroid carcinoma （DTC） with cervical lymph node negative（ cNO stage）. Methods：Thirty-six cases （39 sides） with cN0 DTC were treated with central lymph node dissection, and the clinical effects were observed after surgery. Results： The positive rates of central lymph node were 41.03% （16/39）. One case appeared transient hoarseness, and no permanent hypocalcemia convulsions and other complications were found. All cases were followed up for 1 to 6 years,3 cases with lymph node-positive in VI District recurred carcinoma,who were treated with lateral lymph node dissection again. Conclusions： Central lymph node metastasis of differentiated thyroid carcinoma with cN0 stage is in common, central lymph node dissection for treating differentiated thyroid carcinoma is safe and feasible.
