甲状腺癌是内分泌系统最常见的恶性肿瘤,其发病率呈逐年上升的趋势。分化型甲状腺癌(differentiated thyroid carcinoma,DTC)是其中最常见的类型,其特点是病程较长、预后相对较好,且残余甲状腺或转移灶具有摄取131I的特性。因此,目前临床上多采用甲状腺癌切除术结合131I治疗的方法[1]。
DTC特别是乳头状癌易发生颈部淋巴结转移,而超声是检测颈部淋巴结最为灵敏的方法,因此,通过超声及超声引导下淋巴结细针穿刺细胞学检查(fine needle aspiration cytology,FNAC)准确判断颈部淋巴结的性质对决定是否手术或131I治疗,以及131I治疗后的随访均有重要的意义。本文仅就颈部超声在DTC 131I治疗中的应用综述如下。

摘要: 分化型甲状腺癌是内分泌系统最常见的恶性肿瘤,其发病率呈逐年上升的趋势。其中,乳头状癌易发生颈部淋巴结转移。超声和超声引导下细针穿刺在颈部淋巴结转移检测方面具有很高的灵敏度和特异度。准确判断颈部淋巴结的性质对决定是否再次手术或131I治疗,以及131I治疗后的随访均有重要意义。Abstract: Differentiated thyroid carcinoma is the most common malignant tumor of the endocrine system, with an increasing incidence rate in recent years. Patients with papillary thyroid carcinoma might have a high incidence of cervical lymph node metastasis. Ultrasound and ultrasound guided fine-needle aspiration cytology is a highly sensitive and specific process for detecting the cervical lymph node metastasis. And the accurate determination of the characteristics of cervical lymph nodes is critical to make the choice of reoperation, 131I radiotherapy and follow-up after 131I therapy as well.
