目的探讨老年乳头状甲状腺癌患者的X线计算机体层成像(CT)特征与颈部淋巴结转移的关系,为临床诊断提供参考依据。方法采用方便抽样方法对在北京市和辽宁省沈阳市4家医院2008年1月—2013年12月经手术病理证实的400例老年乳头状甲状腺癌患者进行CT检查。结果 400例老年乳头状甲状腺癌患者中,259例患者发生颈部淋巴结转移,转移率为64.75%;发生颈部淋巴结转移患者肿瘤大小≥2 cm、病灶坏死、病灶周围侵犯、强化特点为重度的比例分别为83.40%、77.99%、97.89%、92.66%,均高于未发生颈部淋巴结转移患者的44.68%、63.12%、54.61%、59.57%,差异均有统计学意义(P<0.01)。结论老年乳头状甲状腺癌患者的CT特征可以初步判断颈部淋巴结是否发生转移。
Objective To investigate the relationship between X-ray computed tomography (CT) features and cervical lymph node metastasis in elderly patients with papillary thyroid carcinoma and provide a reference for clinical diagnosis. Methods A total of 400 elderly patients with papillary thyroid carcinoma confirmed by surgery and pathology from January 2008 to December 2013 in Shenyang and Shenyang, Liaoning Province were enrolled in this study. Results Of 400 elderly patients with papillary thyroid carcinoma, 259 patients had cervical lymph node metastasis with a metastasis rate of 64.75%. Patients with cervical lymph node metastasis had a tumor size of ≥2 cm, necrosis of the lesion and perihepatic lesions with severe enhancement The proportions were 83.40%, 77.99%, 97.89% and 92.66%, respectively, which were all higher than those of patients without cervical lymph node metastasis (44.68%, 63.12%, 54.61% and 59.57%, respectively). Conclusion CT features of elderly patients with papillary thyroid cancer can be a preliminary assessment of cervical lymph node metastasis.
