本文对１４７例脑转移瘤伽玛刀治疗后随访资料进行分析，其结果表明：无论原发灶来源于什么脏器，各类脑转移瘤对伽玛刀治疗均甚敏感，降低了由脑转移瘤引发的死亡率。辅助全脑低剂量普通放射治疗能够预防或延迟颅内再发转移肿瘤。边缘照射剂量低于１４ＧＹ治疗无效。资料提示伽玛刀是一种有效的，损伤较小的，适用于中、小体积，估计存活超过３个月的脑转移瘤患者的治疗方法，对于多发转移瘤及手术不可及的部位更具独特疗效 This article analyzes the follow-up data of 147 cases of brain metastases after gamma knife treatment. The results show that: regardless of the origin of the primary organ from which the various types of brain metastases are sensitive to gamma knife treatment, reduced by the brain Tumor-induced mortality. Adjuvant whole brain low-dose common radiotherapy can prevent or delay intracranial recurrence of metastatic tumors. Edge irradiation dose is lower than 14GY treatment is ineffective. The data suggest that Gamma Knife is an effective, less-invasive method that is suitable for medium and small volumes. It is estimated that patients with brain metastases who have survived for more than 3 months are more likely to have multiple metastases and sites beyond surgery. Unique efficacy
