目的比较脑转移瘤的 Ｘ刀治疗与常规手术治疗的疗效及特点。方法在１１６例脑转移瘤患者中，对４７例采用 Ｘ刀治疗、 ６９例作常规手术治疗；其中４例联合运用两种方法。结果无围手术期死亡患者：随访全部病例两组生存期在６个月内者分别为１５％（４／４７）和１６％（１１／６９），生存期达６个月以上者为８５％和８４％。结论Ｘ刀及常规手术治疗脑转移瘤各有其临床特点，颅内多发、新生及复发肿瘤仍适应于Ｘ刀治疗，两种方法结合使用可以明显增加脑转移瘤的治疗机会，延长晚期肿瘤患者的生存期，减少恶性肿瘤的颅脑源性死亡率。
Objective To compare the efficacy and characteristics of X knife and conventional surgical treatment of brain metastases. Methods In 116 patients with brain metastases, 47 cases were treated with X knife and 69 cases were treated by conventional surgery. Four of them combined with two methods. Results No perioperative deaths were observed: Follow-up The survival rates of both groups were 15% (4/47) and 16% (11/69) in the 6-month follow-up, respectively, and those with survival of 6 months or more were 85% And 84%. Conclusion X-knife and conventional surgical treatment of brain metastases have their own clinical features, multiple intracranial, neonatal and recurrent tumors are still adapted to the X knife treatment, the combination of the two methods can significantly increase the chance of treatment of brain metastases, prolongation of advanced cancer patients Survival and reduce the brain-derived mortality of malignant tumors.
