放疗是脑肿瘤综合治疗中的一个重要组成部分,理想的放疗方法不但要求能杀伤肿瘤细胞,又不损害正常的脑组织结构与功能。目前,常用的~(60)CO、X—射线、加速器等放疗方法很难满足上述条件,虽然部分病人可以延长生命,但也会发生脑损害的并发症,如脑水肿、迟发性脑坏死、痴呆样的神经功能减退等,尤其治疗剂量超过50Gy 时更是如此。硼中子俘获疗法(Boron Neutron CaptureTherapy,BNCT)可选择性的杀伤肿瘤细胞,不
Radiation therapy is an important part of the comprehensive treatment of brain tumors. The ideal radiotherapy method not only can kill the tumor cells, but also not damage the normal brain tissue structure and function. At present, the commonly used ~ (60) CO, X-ray, accelerator and other radiotherapy methods is difficult to meet the above conditions, although some patients can prolong life, but also complications of brain damage, such as cerebral edema, delayed cerebral infarction , Dementia-like neurological deficits, and more, especially when the therapeutic dose exceeds 50 Gy. Boron Neutron Capture Therapy (BNCT) selectively kills tumor cells without
