放射性脑损伤的发病机制及治疗

Study of pathogenesis and therapeutics of radiation-induced brain injury

放射性脑损伤是脑与头颈部恶性肿瘤放射治疗后常见的并发症。近年来随着脑与头颈部肿瘤放射治疗技术的日渐推广，该病发病率逐年升高，严重影响了患者的生活质量和生存期，因而对放射性脑损伤的研究显得较为迫切。本文综述了其发病机制及治疗措施，为减少放射性脑损伤的发生及采取科学合理的治疗措施提供参考。

Radiation-induced brain injury is a well-described complication of brain and neck cancers radiotherapy. With the increasing use of radiotherapy for brain and neck cancers in recent years,the incidence of radiation-induced brain injury which has influenced the sufferer＇s living quality and existence period seriously has markedly increased. As a result, the research to the radiation-induced brain injury seems to be more urgently. The article reviewed the mechanism and treatment and wanted to provide a reference for the treatment which reduces incidence of radiation-induced brain injury.
