分化型甲状腺癌(differentiated thyroid carcinoma,DTC)是颈部最常见的恶性肿瘤,也是甲状腺癌最主要的类型。DTC早期就存在颈淋巴结转移,且以中央区淋巴结转移最为常见,被称为“前哨淋巴结”。对于颈中央区淋巴结阳性(cN+)的病人,在手术处理原发灶的同时,行相应的颈中央区淋巴结清扫已达成共识,但对临床颈中央区淋巴结阴性(cN0)的DTC病人,是否行预防性颈部淋巴结清扫仍是国内
Differentiated thyroid carcinoma (DTC) is the most common malignant tumor in the neck and the most common type of thyroid cancer. DTC early cervical lymph node metastasis, and the most common central lymph node metastasis, known as “sentinel lymph node ”. For cN + patients with central cervical lymph nodes, consensus has been reached on the corresponding central neck lymph node dissection at the same time as the surgical treatment of the primary tumor. However, for patients with clinically cN0 negative lymph node (cN0) DTCs Preventive cervical lymph node dissection is still the country
