目的:探讨预防性颈中央区淋巴结清扫在c N0分化型甲状腺癌(DTC)分期与复发危险度分层中的意义。方法:对2014年3月—7月收治的95例c N0 DTC行甲状腺切除及预防性中央区淋巴结清扫患者的临床病理资料行回顾性分析。结果:95例患者预防性中央区淋巴结清扫术后,43例见颈中央区淋巴结转移(45.3%),其中10例(10.5%)肿瘤TNM分期上移,分别为I期→III期8例,II期→III期2例;39例(41.1%)复发危险度提高。结论:预防性颈中央区淋巴结清扫能提高c N0 DCT患者TNM分期和复发危险度分层的准确性,从而有助于术后治疗方案的确定。
Objective: To investigate the significance of prophylactic cervical central lymph node dissection in the stratification and recurrence risk stratification of c00 differentiated thyroid cancer (DTC). Methods: A retrospective analysis was performed on 95 patients with c N0 DTC undergoing thyroidectomy and prophylactic central lymph node dissection from March 2014 to July 2014. Results: Of the 95 patients who underwent prophylactic central lymph node dissection, 43 cases were found to have lymph node metastasis (45.3%) in the central area of the neck. Among them, 10 (10.5%) patients had TNM staging upwards in stage I, Stage II to III stage 2 cases; 39 cases (41.1%) increased the risk of relapse. Conclusion: Preventive cervical central lymph node dissection can improve the accuracy of stratification of TNM staging and recurrence risk in patients with c N0 DCT, which is helpful for the determination of postoperative treatment regimen.
