超声特征预测甲状腺微小乳头状癌颈侧区淋巴结转移的临床应用价值分析

目的探讨超声特征预测甲状腺微小乳头状癌颈侧区淋巴结转移的临床应用价值。方法采取回顾性方法对宁波市鄞州区第二医院超声科2011年1月～2012年1月120例甲状腺微小乳头状癌患者术前超声诊断资料与术后颈侧区淋巴结转移病理结果进行分析。结果颈侧区淋巴结转移阳性患者的肿瘤边界、钙化、肿瘤位置、甲状腺被膜与肿瘤关系和颈侧区淋巴结转移阴性患者的肿瘤边界、钙化、肿瘤位置、甲状腺被膜与肿瘤关系情况比较具有明显的差异（P〈0．05），有统计学意义。颈侧区淋巴结转移阳性患者不同超声积分与颈侧区淋巴结转移阴性患者不同超声积分比较具有明显的差异，有统计学意义（P〈0．05）。以超声积分为2．5作为临界点，积分≥2．5分时甲状腺微小乳头状癌患者颈侧区淋巴结很有可能发生转移，临床诊断敏感性与特异性分别是86．0％、90．0％。结论临床中对于甲状腺微小乳头状癌患者应用超声积分能够有效地对颈侧区淋巴结转移进行诊断，在临床中具有重要的应用价值。

Ultrasonic features of papillary microcarcinoma of thyroid neck lymph node metastasis and clinical application value

Objective To investigate the sonographic features of papillary thyroid carcinoma predicted lateral neck lymph node metastasis of clinical applications. Methods By a retrospective method of Department of Ultrasound in Second Hospital of Yinzhou District, Ningbo City, from January 2011 to January 2012, a total of 120 patients with papillary thyroid microcarcinoma uhrasonography before and after lateral lymph nodes metastasis and pathological results were analyzed. Results Lateral neck lymph node metastasis patients with tumor boundary, calcification, tumor location, the thyroid was relation between the film and the tumor and neck lymph node metastasis negative patients with tumor margin, calcification, tumor location, the thyroid by comparison between membrane and tumor with significant difference（P 〈 0.05）, had statistically significant. Lateral neck lymph node metastasis in patients with different ultrasonic positive integral and neck lymph node metastasis negative patients with different ultrasonic integral comparison had the obvious difference, there was statistically significant （P 〈 0.05）. With ultrasonic score of 2.5 as the critical point, score t〉 2.5 points of papillary thyroid microcarcinoma patients with neck lymph node metastasis was likely to occur, clinical diagnostic sensitivity and specificity were 86.0%, 90.0%. Conclusion For clinical application in patients with papillary thyroid ultrasound integration can effectively carry on the lateral neck lymph node metastasis diagnosis has important clinical application value.
