摘要
目的 探讨术前超声特征与甲状腺微小乳头状癌颈侧区淋巴结转移的关系.方法 回顾性分析本院收治的165例甲状腺微小乳头状癌患者,收集其甲状腺癌结节的超声影像学资料及术后颈侧区淋巴结病理结果,分析得出其相关因素并予以不同评分.结果 颈侧区淋巴结转移阳性患者中微钙化、肿瘤边界不清晰、肿瘤位于上极及肿瘤与甲状腺被膜的接触部分＞25％的肿瘤周长发生率均高于阴性患者（P＜0.05）.超声积分在颈侧区淋巴结转移阳性组与阴性组间差异有统计学意义,以超声积分≥2.5分为分界值,其敏感性为86.2％,特异性为89.7％.结论 超声积分对甲状腺微小乳头状癌患者颈侧区淋巴结转移的鉴别诊断具有一定的预测价值,当超声积分≥2.5时需注意颈侧区淋巴结转移可能.
Objective To probe into the ultrasonic（US） predictive value for metastasis of the cervical lateral lymph node（LNM） with the preoperative ultrasonic examination in thyroid papillary microcarcinoma （PTMC）,then,to further evaluate the significance of the preoperative ultrasonic score （US） for predicting metastasis of the cervical lateral lymph node.Methods From May 2004 to May 2011,165 patients diagnosed as PTMC （the ultrasonic imaging of lymph node showed no lateral LNM） were retrospectively analyzed and the US and final pathological data from the cases were collected to determine the relevant factors and different scores.Results There were significant differences （P 〈 0.05 ） among US characteristics of microcalcification,no well-defined margin,tumor located at the upper pole,the perimeter of the tumor contacted with the adjacent capsule of thyroid being 〉25 % and the presence of the cervical lateral lymph nodes metastasis in PTMC between the metastatic group and the non-metastatic group.The total scores of the ultrasonic ≥2.5 was the delimitation value,its sensitivity was 86.2% and its specificity was 89.7%.Conclusions The ultrasonic score has definite value in the differential diagnosis for the metastasis of the cervical lateral node in the patients of no lateral LNM,when the ultrasonic score is larger than 2.5,the possibility of the cervical lateral lymph node metastasis should be noticed.
