目的探讨多处方剂量融合正向调强全脑放疗同期推量治疗计划在治疗脑转移瘤中的可行性。方法20例脑转移瘤患者,利用Pinnacle6.2适形治疗计划系统,进行全脑放疗同期推量治疗:全脑放疗TD30Gy/10F,转移瘤推量20Gy/10F。结果所有患者均顺利完成治疗,未出现临床不可接受的副反应。结论多处方剂量融合正向调强全脑放疗同期推量治疗脑转移瘤,在临床上是可行的,对于KPS评分较好,原发病灶控制的脑转遗瘤患者可以推荐使用。
Objective To investigate the feasibility of using multi-prescription dose fusion plus forward-modulated whole-brain radiation therapy with concurrent push therapy in the treatment of brain metastases. Methods Twenty patients with brain metastases were treated with Pinnacle 6.2 conformal treatment planning system for simultaneous whole-brain radiation therapy: TD30Gy / 10F for whole brain radiation and 20 Gy / 10F for metastases. Results All patients successfully completed the treatment without clinical unacceptable side effects. Conclusions Multi-prescription dose fusion forward-modulated whole-brain radiation therapy for simultaneous treatment of brain metastases is feasible in clinical practice. For those with better KPS score, patients with brain metastasis treated by primary lesion may be recommended.
