[目的]比较两种不同放射分割治疗脑转移瘤的疗效。[方法]对30例脑转移性肿瘤进行分组研究 ,常规分割组18例 ,全颅照射40Gy/20F ,4W ,部分病例病灶区加量20Gy/10F ,2W。大分割组12例 ,全颅照射30Gy/10F ,2W ,部分病例病灶区加量15Gy/5F ,1W。[结果]2组病例急性反应、耐受性、即期疗效及生存期比较无明显差异。[结论]脑转移性肿瘤大分割治疗能缩短治疗时间 ,提高生存质量 ,治疗的急性反应、疗效及生存期与常规分割相仿 ,是一种值得推广的治疗方法。
[Objective] To compare the curative effect of two different radiosensitive devices in the treatment of brain metastases. [Methods] Thirty cases of brain metastatic tumors were divided into groups, 18 cases in conventional group and 40Gy / 20F, 4W in whole cranium. The volume of lesion in some cases was 20Gy / 10F and 2W. Large divisions in 12 cases, the whole skull irradiation 30Gy / 10F, 2W, in some cases the lesion area dosage 15Gy / 5F, 1W. [Results] There was no significant difference in acute response, tolerability, immediate efficacy and survival between the two groups. [Conclusion] Segmentation of brain metastatic tumor can shorten the treatment time and improve the quality of life. The acute response, the curative effect and the survival period of the brain metastatic tumor are similar to the conventional ones. It is worth to be popularized.
