More than 50% of all cancer patients receive radiation therapy. The clinical delivery of curative radiation dose is strictly restricted by the proximal healthy tissues. We propose a dual-targeting strategy using vessel-targeted-radiosensitizing gold nanoparticles and conformal-image guided radiation therapy to specifically amplify damage in the tumor neoendothelium. The resulting tumor vascular disruption substantially improved the therapeutic outcome and subsidized the radiation/nanoparticle toxicity, extending its utility to intransigent or nonresectable tumors that barely respond to standard therapies.
超过50%的癌症患者接受放射治疗。根治性放射剂量的临床递送受到近端健康组织的严格限制。我们提出了一种双靶向策略,使用血管靶向放射增敏金纳米颗粒和适形图像引导放射治疗,以特异性放大肿瘤新生内皮中的损伤。由此产生的肿瘤血管破坏显著改善了治疗效果,并减轻了放射/纳米颗粒毒性,将其应用扩展到对标准疗法几乎没有反应的难治性或不可切除肿瘤。
