摘　　要：目的观察三维适形放疗治疗中晚期非小细胞肺癌的临床疗效及毒副反应。方法采用CTsim系统精确定位及TPS计划系统将扫描图像进行三维重建,从而获得理想剂量分布,每天1次分割剂量220～300cGy/次,每天2次分割剂量150cGy/次,总剂量6000～7500cGy。结果全组CR20例,PR23例,NC3例,PD3例,有效率87.8%。结论对于中晚期非小细胞肺癌的患者,三维适形放疗技术是一种安全、有效的治疗手段,能够改善生存质量,提高生存率。Objective To evaluate the treatment result and adverse effect of three dimensional conformal radiotherapy for unresectable advanced patients with non small cell lung cancer（ NSCLC ）. Methods CTsim system used to set accurate position and TPS plan system used to rebuilt the 3D picture with the original scanning for getting ideal prescription doze 220-300cGy per fraction per day and 150cGy per fration twice perday, total doze at 6000-7500cGy. Results CR 20 patients,PR 23 patients,NC 3 patients,PD 3 patients,and total efficient was 87.8%. Conclusion Three dimensional conformal radiotherapy is an safety and effiency method to treat unresectable advanced patients with non small cell lung cancer to improve living quality and survive ratio.
