项目摘要

ABSTRACT Hepatocellular carcinoma (HCC) accounts for 80 to 90% of primary liver cancer. It is the fifth most common malignancy and is the third most common cause of cancer-related death. This application will test the novel approach of antivascular ultrasound for treating HCC. Our preliminary studies show that low- level ultrasound with intensities comparable to those used in treating physiotherapy patients, when used with microbubbles, disrupts tumor neovasculature and improves the survival of animals with implanted tumors. The goals of the research are to demonstrate the efficacy of antivascular ultrasound for treating HCC, and to identify the conditions of treatment that have high efficacy as measured both by imaging and survival of the animals with implanted liver tumors. The proposal has three Specific Aims. Specific Aim 1 will investigate the relationship between blood flow and temperature change. Specific Aim 2 will determine the ultrasound exposure conditions that produce tumor antivascular activity at the lowest possible exposure to ultrasound. Specific Aim 3 will evaluate the short-term and the long term-term therapeutic efficacy of single and multiple ultrasound treatments. We anticipate that the knowledge gained from the proposed research will lead to a new form of antivascular or vascular disrupting treatment for HCC. Of particular interest would be the ability of antivascular ultrasound to treat non-resectable small and large cancers frequently observed clinical. Advantages include the simplicity and small cost of low-intensity ultrasound technology, the use of quantitative ultrasound imaging to assess and monitor therapeutic efficacy at the time of treatment, and fewer unwanted side effects from the low-intensity ultrasound therapy compared to cytotoxic therapies. We anticipate that the results of this study will facilitate the translation of a novel ultrasound technology to the treatment of patients with HCC.
摘要 肝细胞癌(HCC)占原发性肝癌的80 - 90%。它是第五个最 是常见的恶性肿瘤,是癌症相关死亡的第三大常见原因。该应用程序将测试 抗血管超声治疗肝癌的新方法。我们的初步研究表明- 使用时,水平超声的强度与治疗物理治疗患者时使用的强度相当 与微泡,破坏肿瘤新生血管和提高动物的生存与植入 肿瘤的 该研究的目的是证明抗血管超声治疗HCC的有效性, 通过成像和存活率测定,确定具有高疗效的治疗条件, 移植了肝脏肿瘤的动物。 该提案有三个具体目标。具体目标1将研究血流量 和温度变化。特定目标2将确定产生 肿瘤抗血管活性在最低可能暴露于超声波。具体目标3将评估 单次和多次超声治疗的短期和长期治疗效果。 我们预计,从拟议的研究中获得的知识将导致一种新形式的抗血管 或肝细胞癌的血管阻断治疗。特别令人感兴趣的是, 超声波治疗不可切除的小型和大型癌症经常观察到的临床。优点包括 低强度超声技术的简单性和小成本,使用定量超声 在治疗时进行成像以评估和监测治疗效果, 与细胞毒性疗法相比,低强度超声疗法的效果。我们预计 这项研究的结果将促进一种新的超声技术的翻译,以治疗 HCC患者。
