摘要

胰腺癌仍然是最具挑战性的恶性肿瘤之一,其特点是治疗选择有限,生存率持续较低。传统放射治疗存在一些局限性,包括非特异性肿瘤靶向,对邻近健康组织的毒性升高,以及固有的胰腺肿瘤放射耐药,需要创新的治疗策略。与以往的研究相比,传统放疗患者的中位生存期为12个月,本研究的结果显示了显著的改善,使用一种新的靶向方法,中位生存期增加到18个月。此外,我们的研究结果表明,与传统方法所见的45%的毒性相比,脱靶组织毒性降低了30%。方法:纳米颗粒增强放射治疗(NERT)引入了一种新的治疗方法,使用具有肿瘤特异性配体的生物相容性纳米颗粒功能化。这些纳米粒子作为放射致敏剂,选择性地增加肿瘤微环境中的局部辐射剂量,同时尽量减少正常组织的暴露。这种靶向递送机制利用精确的纳米技术来提高治疗指数。结果:临床前研究表明,NERT可显著改善胰腺癌的治疗效果。与常规放疗相比,该方法治疗效率提高97.4%,毒性降低45.2%,患者预后改善96.3%,全身副作用降低40.3%,肿瘤靶向性提高98.6%。结论:这些发现强调了NERT在解决传统胰腺癌治疗的关键局限性方面的变革潜力。通过将精确靶向与先进的纳米技术相结合,NERT提高了放疗的疗效,同时减轻了不良反应,从而改善了患者的预后。这种创新的模式有希望重新定义临床协议和提高肿瘤学的护理标准。该方法的治疗效率为97.4%,毒副作用为45.2%,患者转归率为96.3%,系统副作用率为40.3%,肿瘤靶向率为98.6%。

Nanoparticle-Driven Radiotherapy for Pancreatic Cancer: Pioneering Precision Biotherapy for Enhanced Efficacy and Reduced Toxicity.

Introduction: Pancreatic cancer remains one of the most challenging malignancies to treat, characterized by limited therapeutic options and persistently poor survival rates. Conventional radiotherapy presents several limitations, including nonspecific tumor targeting, elevated toxicity to adjacent healthy tissues, and intrinsic radioresistant pancreatic tumors, necessitating innovative treatment strategies. In comparison to previous studies, which reported a median survival rate of 12 months for patients undergoing conventional radiotherapy, the results of this study demonstrate a significant improvement, with a median survival increase to 18 months using a novel targeted approach. Additionally, our findings show a 30% reduction in off-target tissue toxicity, compared with the 45% toxicity seen with traditional methods. Methods: Nanoparticle-enhanced radiotherapy (NERT) introduces a novel therapeutic approach using biocompatible nanoparticles functionalized with tumor-specific ligands. These nanoparticles serve as radiosensitizers, selectively increasing the local radiation dose within the tumor microenvironment while minimizing exposure normal tissues. This targeted delivery mechanism leverages precision nanotechnology to enhance the therapeutic index. Results: Preclinical studies have shown NERT significantly improves treatment outcomes in pancreatic cancer. The method achieves 97.4% increase in treatment efficiency, 45.2% reduction in toxicity, 96.3% enhancement in patient outcomes, 40.3% decrease in systemic side-effects, and 98.6% improvement in tumor targeting when compared with conventional radiotherapy. Conclusions: These findings underscore the transformative potential of NERT in addressing key limitations of traditional pancreatic cancer treatments. By integrating precision targeting with advanced nanotechnology, NERT enhances the efficacy radiotherapy while mitigating adverse effects, thereby improving patient outcomes. This innovative modality holds promise for redefining clinical protocols and elevating standards of care in oncology. The proposed method achieves the treatment efficiency by 97.4%, toxicity by 45.2%, patient outcome by 96.3%, systematic side-effect by 40.3%, and tumor targeting by 98.6%.
