超声在喉癌及下咽癌颈部淋巴结转移中的诊断价值

Diagnostic value of ultrasonography in metastasis of cervical lymph nodes in patients with larynx and hypopharynx carcinoma

目的探讨超声在喉癌及下咽癌颈部淋巴结转移中的诊断价值。方法术前超声检查48例喉癌及下咽癌患者的颈部淋巴结,超声所见与手术切除病理结果对照分析。结果超声检查与病理结果对照,符合的淋巴结172个,符合率为64.2%。多因素Logistic回归分析结果显示,淋巴结内部回声不均、髓质变形或缺失,周边型及混合型血流预示淋巴结有转移。超声诊断淋巴结转移的敏感性为91.8%,特异性为87.8%,准确性为90.1%。结论超声检查对喉癌及下咽癌颈部淋巴结转移具有较高的诊断价值。

Objective To investigate the value of ultrasonography in diagnosis of the cervical lymph nodes（CLN） metastases of larynx and hypopharynx carcinoma. Methods CLN of 48 patients with larynx and hypopharynx carcinoma were observed with ultrasonography before operation, the results were compared with operation and pathological findings. Results A total of 172 CLN in 48 cases were analyzed, with a accordance rate of 64.2 %. Multivariate logistic regression analysis revealed that lymph nodes with inhomogenous internal echo,eccentric medulla or medulla defect, peripheral and mixed vascular pattern suggested metastasis. The sensitivity, specificity and accuracy of ultrasonography in evaluating metastasis were 91.8 %, 87.8 % and 90.1%. Conclusion Ultrasonography is valuable in detecting metastatic lymph nodes in patients with larynx and hypopharynx carcinoma.
