作者应用Ｘ－刀治疗颅内肿瘤１１６例，大部分为中、小肿瘤，部分颅内巨大肿瘤采用联合开颅手术方式。随访１～６个月的结果显示，Ｘ－刀治疗后，９６例（８２．８％）肿瘤有影像学改变，其中部分肿瘤囊性变和缩小．对于巨大肿瘤，Ｘ－刀治疗后再手术可降低手术难度，部分病例的病理检查亦提示该结果，根据最大剂量与周边剂量之比和治疗体积与靶体积之比，进行治疗计划的优化，可以有效地减少并发症及提高疗效。
The authors applied X-knife treatment of intracranial tumors in 116 cases, most of the small and medium-sized tumors, some of the large intracranial tumors using a joint craniotomy.

For huge tumors, X-knife surgery can reduce the surgical re-operation difficulty, pathological examination in some cases also prompted the results, according to the maximum dose and peripheral dose ratio and treatment volume to target volume ratio, the treatment plan can be optimized, you can Effectively reduce complications and improve efficacy.
