目的评价调强适形放射治疗脑膜肉瘤的疗效。方法对我院2001年8月收治的1例经病理证实为左颈静脉孔区脑膜肉瘤合并右颞叶胶质瘤术后患者用调强适形放射治疗的临床资料。结果患者男,34岁,行肿瘤活检术后4周,先常规放射治疗,每次200cGy,每周5次,总量3000cGy;后程调强适形放射治疗,每周3次,每次416cGy,总剂量2500cGy。放疗后左颈静脉孔区脑膜肉瘤明显缩小,随访2年带瘤生存。结论对不能手术的脑膜肉瘤使用常规放疗加后程调强适形放射治疗可取得较好的疗效,放疗反应小。
Objective To evaluate the efficacy of intensity modulated conformal radiation therapy of meningioma. Methods One patient admitted to our hospital in August 2001 was confirmed by pathology as the clinical data of patients with meningio sarcoma in the left jugular foramina with right temporal glioma treated with intensity modulated conformal radiotherapy. Results The patient, 34 years old, had a routine radiotherapy of 200 cGy four times a week after the tumor biopsy, with a total volume of 3000 cGy. Afterward, IMRT was repeated three times a week for 416 cGy , Total dose 2500cGy. Radiotherapy after left jugular foramen of meninosarcoma was significantly reduced, followed up for 2 years with tumor survival. Conclusion The use of conventional radiotherapy and subsequent intensity-modulated conformal radiotherapy for inoperable meningeal sarcoma can achieve better efficacy and less radiotherapy response.
