目的:观察IMRT联合化疗治疗脑瘤的疗效以及放疗量效的关系。方法:82例患者随机分组,统计分析单纯IMRT治疗与联合化疗治疗的差异,及放疗量效的关系。结果:IMRT联合化疗治疗组比单纯IMRT组有效率明显提高,差异有显著性(P<0.05);DT≥60Gy比DT<40有效率明显提高,差异有显著性(P<0.05)。结论:IMRT联合化疗能更有效的控制肿瘤发展;肿瘤量DT与疗效呈正相关。
Objective: To observe the curative effect of IMRT combined with chemotherapy on brain tumor and the relationship between the curative effect and radiotherapy dose. Methods: Eighty - two patients were randomly divided into two groups. The difference between simple IMRT and chemotherapy and the effect of radiotherapy were statistically analyzed. Results: The effective rate of IMRT combined with chemotherapy group was significantly higher than that of IMRT group (P <0.05). The effective rate of DT≥60Gy was significantly higher than that of DT <40 (P <0.05). Conclusion: IMRT combined with chemotherapy can effectively control the tumor development; the amount of tumor DT has a positive correlation with the curative effect.
