原发性或转移性脑部恶性肿瘤患者接受放射治疗时，会引起脑组织功能和形态学变化，导致放射性脑损伤，并且其发病机制尚无统一定论，现有的研究进展和治疗方案有待阐明和完善。本综述从血管损伤、炎症反应、神经元功能障碍、胶质细胞损伤以及肠道微生物方面讨论放射性脑损伤的发病机制，以及治疗与预防的相关研究进展，旨在为放射性脑损伤的研究和临床诊治提供参考和理论依据。 Radiotherapy can cause functional and morphological changes in the brain tissues of patients with primary or metastatic malignant brain tumors, leading to radiation-induced brain injury. However, the pathogenesis of radiation-induced brain injury has not yet been unanimously determined, and its research advances and treatment protocols are yet to be elucidated and improved. In this study, we explore the pathogenesis of radiation-induced brain injury from the perspective of vascular injury, inflammatory reactions, neuronal dysfunction, glial cell injury, and gut microbiota and reviewed the advances in research on its treatment and prevention. The purpose is to provide a reference and theoretical basis for the research and clinical diagnosis and treatment of radiation-induced brain injury.
