甲状腺微小乳头状癌超声特征与颈侧区淋巴结转移关系的探讨

摘要

目的 探讨甲状腺微小乳头状癌术前超声特征与颈侧区淋巴结转移的关系.方法 回顾性分析辽河油田总医院收治的140例甲状腺微小乳头状癌患者的临床资料,分析患者淋巴结转移的相关因素并进行评分.结果 颈侧区淋巴结转移阳性患者的肿瘤边界不清晰、钙化、肿瘤位于上极、甲状腺被膜的接触部分＞25％的肿瘤周长的发生率高于颈侧区淋巴结转移阴性患者,差异有统计学意义(P＜0.05)；以2.5分为诊断界点的曲线下面积(AUC)最大,其灵敏度为0.846,特异度为0.786,AUC为0.891.可以认为超声积分2.5分是鉴别PTMC患者颈侧区淋巴结转移的最佳诊断界点.结论 超声积分2.5分是鉴别PTMC患者颈侧区淋巴结转移的最佳诊断界点.若甲状腺癌结节积分＜2.5分,则颈侧区淋巴结不转移的可能性较大；若甲状腺癌结节积分≥2.5分,则颈侧区淋巴结转移的可能性较大.%Objective To investigate the relationship between ultrasound characteristics of thyroid the minute papillary cancer surgery and sides of neck lymph node metastasis.Methods The clinical data of 140 cases of thyroid micro papillary carcinoma patients in Liaohe Oilfield General hospital were retrospective analyzed,the relevant factors of patients with lymph node metastasis were analyzed and scored.Results The incidence in base of the throat area lymph node metastasis in patients with positive tumor boundary was not clear,calcification,the tumor was located in the upper pole,the contact portion of the thyroid capsule lymph node metastasis-negative patients with＞25％ were higher than the perimeter of tumor at the base of the throat area; The difference was statistically significant(P＜0.05); the 2.5score as the cut-off point of AUC,the sensitivity was 0.846,specificity was 0.786,AUC was 0.891.The score 2.5could as the identification of PTMC patients with neck lymph node metastasis of the best diagnosis field.Conclusion Ultrasound 2.5 is the best diagnostic sector point for identification PTMC patients with lateral neck lymph node metastasis.Thyroid cancer nodules Credits＜2.5,the lateral neck lymph node likely no transfer;,thyroid cancer nodules score≥ 2.5,the lateral neck lymph node likely no transfer.
