摘要
肿瘤患者容易发生脑转移,立体定向放射外科(SRS)是脑寡转移肿瘤有效的治疗手段。然而,SRS对于体积较大的转移病灶并不适宜。分次立体定向放疗(FSRT)是一种较新的治疗脑转移瘤的技术手段,能在给予转移病灶较高照射剂量的同时尽可能保护照射野之外的正常组织及器官,且治疗后脑转移病灶局部控制率良好。文章对不同分割方案FSRT的剂量效应关系、不良反应以及FSRT与靶向治疗、免疫治疗联合应用的进展进行介绍。
Brain metastases are common in oncologic patients.Stereotactic radiosurgery(SRS)is an effective treatment for oligo brain metastases.However,SRS is not suitable for large metastatic lesions.Fractionated stereotactic radiation therapy(FSRT)is a new option for the treatment of brain metastases.It can deliver high doses of radiation to tumor while protecting the normal tissues and organs outside the irradiation field as much as possible and maintaining good local control rate of tumors.This article reviews the dose-response relationship and adverse reactions of FSRT with different fractionated dose schemes,and the progress of FSRT combined with targeted therapy and immunotherapy.
