X－刀治疗颅内肿瘤116例报告

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。

X-knife Treatment for 116 Intracranial Tumors

ll6 cases of intracranial tumors treated with X-knife have been reported.Most of them were middle or small tumors, some large ones were treated with X-knife and combination craniotomy.The follow-up interval was 1 to 6 months.Results showed that in 96(82.8%)cases there were imaging changes including cystic degeneration and shrinkage of tumors.For the large tumors,pre-operative X-knife treatment could decrease the difficulty of the operation. Mentioned above findings were also proved by the pathological examination.Selection of treatment plans was based on considerations of the ratios of maximal dose to peripheral dose and treatment volume to target volume. By means of this method, the complicatioin could be decreased and the curative effect could be increased.
