高频彩色多普勒超声对鼻咽癌颈部转移性淋巴结的诊断因素分析

The diagnostic feature analysis of high frequency color Doppler ultrasonography in metastatic cervical lymph nodes of nasepharyngeal carcinoma

目的：探讨高频彩色多普勒超声对鼻咽癌颈部转移性淋巴结诊断的临床应用价值。方法：对37例确诊鼻咽癌患者进行颈部高频多普勒超声检查,预测所探及的转移性淋巴结并与针刺细胞病理学检查结果对照分析。结果：多因素Logistic回归分析结果显示,L/T值≤2、皮髓质及淋巴门结构模糊或消失、淋巴结内血流为Ⅱ~Ⅲ、RI≥0.6预测转移性淋巴结均有意义（P〈0.01）,其中L/T值≤2比RI/≥0.6在预测转移性淋巴结中更有意义。结论：二维超声及彩色多普勒显像等多因素评价指标对鼻咽癌颈部转移性淋巴结的评估诊断具有较高的临床应用价值,可为临床医生评估鼻咽癌患者颈部淋巴结提供依据。

Objective： To discuss the clinical value of high frequency color Doppler ultrasonography in metastatic cervical lymph nodes of nasopharyngeal carcinoma （NPC） . Methods： Thirty NPC patients were observed with high frequency color Doppler ultra- sonography before treatment, the results of predicted metastatic cervical lymph nodes were compared with fine needle aspiration biopsy. Results Multivariate logistic regression analysis revealed that L/T≤2, eccentric medulla or medulla defect, the blood flowing intensi- ties of lymph nodes are Ⅱ - Ⅲ1RI≥0.6 were the sonographic features for metastatic cervical lymph nodes （P 〈0.01）, and L/T≤ 2 was the better index than RI≥0. 6. Conclusions： Two dimensional ultrasound and Color Doppler ultrasound can provides the basis for evaluation lymphnode metastasis of NPC.
