甲状腺乳头状癌超声表现与颈部淋巴结转移的相关性

摘要

Objective:To investigate the correlation of papillary thyroid ultrasound features and cervical lymph node metastases. Methods:Patients with papillary thyroid tumors were selected from March 2013 to March 2014,a to-tal of 142 cases were treated with 160 nodules. Results:For lymph node ultrasound characteristics,cystic necrosis, calcification,lymph nodes and border there were significantly different between 2 groups(P<0. 05). Logistic regres-sion analysis results showed calcification within the primary tumor,lymph node boundary,calcified lymph nodes and cystic necrosis with cervical lymph node metastasis. Conclusion:For papillary thyroid tumors,lymph node cystic nec-rosis and calcification are risk factors of neck lymph node metastasis.%目的：探讨甲状腺乳头状瘤超声表现与颈部淋巴结转移两者的相关性。方法：选取2013年3月到2014年3月收治的甲状腺乳头状瘤患者142例共160个结节。根据术后病理结果将入选患者分为颈部淋巴结转移组；没有发生颈部淋巴结转移的患者则为对照组。结果：转移组和对照组超声检查原发灶超声特征对比，转移组的钙化和毛刺对比对照组有统计学差异。患者的颈部淋巴结超声特征，转移组患者的囊变坏死、钙化、淋巴结边界等对比对照组有统计学差异（ P<0.05）。采用Logistic回归分析对相关的危险因素进行分析，包括原发灶内钙化、淋巴结边界、淋巴结钙化以及淋巴结囊变坏死等4个方面，囊变坏死和淋巴结钙化与甲状腺乳头癌颈部淋巴结转移呈正相关。结论：甲状腺乳头状瘤超声结果显示有淋巴结囊变坏死以及淋巴结钙化是预测是否出现颈部淋巴转移的关键诊断指标。
