The purpose of this study was to differentiate reactively enlarged cervical nodes from metastatic nodes by means of color Doppler flow imaging in patients with oral squamous cell carcinoma.
Enlarged lymph nodes with long-axis diameters greater than 10 mm in 30 patients were classified into 4 groups according to color Doppler flow imaging findings. After the patients underwent neck dissection, the findings were correlated with the pathologic features.
Color Doppler flow imaging detected 58 enlarged nodes with long-axis diameters greater than 10 mm. Thirty-five lymph nodes showed no color flow signals; of these, 32 (91%) were metastatic and 3 were reactive. Of the 12 lymph nodes with central color flow signals, 11 (92%) were reactively enlarged and 1 was metastatic.
The presence of central signals on color Doppler flow imaging appeared to be a significant parameter associated with reactively enlarged benign nodes in patients with oral squamous cell carcinoma.
本研究旨在通过彩色多普勒血流成像鉴别口腔鳞状细胞癌患者反应性增大的颈部淋巴结与转移性淋巴结。
30例长径大于10mm的肿大淋巴结患者，根据彩色多普勒血流成像结果分为4组。患者接受颈部清扫术后，将结果与病理特征进行关联。
彩色多普勒血流成像检测到58个长径大于10mm的肿大淋巴结。35个淋巴结无血流信号；其中32个（91%）为转移性，3个为反应性。12个有中央血流信号的淋巴结中，11个（92%）为反应性肿大，1个为转移性。
彩色多普勒血流成像上中央信号的存在似乎是口腔鳞状细胞癌患者反应性肿大良性淋巴结的一个重要相关参数。
