It is well known that angiogenic processes in growing tumors promote increased vessel density and structural abnormalities. Lymph node metastasis of the head and neck cancer also showed this neo-vascularization features in active phase of metastasis. The purpose of this study is to evaluate the vascular density and morphology in metastatic lymph nodes by using microbubbles as ultrasound contrast-enhancing agent. On the next stage, we intend to use hybrid nanobubbles to introduce some anti-tumor agents or transformed constructs into cancer cells as drug delivery system. We developed novel image-analyzing software to analyze capillary vessels in lymph nodes of the patients. After they underwent neck dissection, all of the patients who showed contrast-enhancement in their lymph nodes had carcinoma metastases in their lymph nodes by histopathological examination. Contrast ultrasound using our software is useful to detect lymph node metastasis of the head and neck cancer.

众所周知，肿瘤生长中的血管生成过程会促进血管密度增加和结构异常。 头颈癌的淋巴结转移在转移活跃期也表现出这种新生血管特征。 本研究的目的是利用微泡作为超声造影剂来评估转移淋巴结的血管密度和形态。 在下一阶段，我们打算使用混合纳米气泡将一些抗肿瘤药物或转化结构引入癌细胞作为药物输送系统。 我们开发了新型图像分析软件来分析患者淋巴结中的毛细血管。 接受颈清扫术后，所有淋巴结造影增强的患者经组织病理学检查均发现淋巴结有癌转移。使用我们的软件进行对比超声有助于检测头颈癌的淋巴结转移。
