摘要:
低剂量放射治疗(LDRT)通常指单次剂量0.5~2.0 Gy或总剂量低于10.0 Gy的放射治疗方式,其在降低正常组织毒性的同时保留抗肿瘤效应,具有免疫调节、血管正常化和肿瘤微环境重塑等独特生物学效应。然而,肿瘤放射抗性严重制约了LDRT的临床疗效。肿瘤放射抗性的形成涉及多重机制,包括DNA损伤修复系统过度激活、细胞周期检查点失调、抗凋亡通路激活、肿瘤微环境重塑、活性氧稳态失衡和表观遗传学改变等。近年来,多种新型增敏策略被开发并用于协同LDRT抑制放射抗性,包括基于高原子序数纳米材料的放射治疗增敏、靶向谷胱甘肽系统的氧化应激调控、针对糖酵解关键酶的代谢重编程和联合免疫检查点抑制剂的免疫调控等,相关策略在LDRT中显示出特别的应用前景。本研究阐明肿瘤放射抗性形成的分子机制,重点综述了放射治疗增敏策略的应用和机制,并从剂量优化、安全性评估和技术创新3个维度分析了临床转化面临的挑战,旨在为放疗增敏策略的优化设计和临床应用提供理论依据。
