| 摘 要：［目的］ 比较局部晚期非小细胞肺癌(NSCLC)常规静态调强(step-and-shoot intensity-modulated radiation therapy，sIMRT)和容积旋转调强(volumetric modulated arc therapy，VMAT)的临床效果。［方法］ 回顾性分析68例分别行IMRT和VMAT的NSCLC患者资料，IMRT组38例，VMAT组30例。比较两组患者的近期、远期疗效及急性不良反应。［结果］ IMRT组和VMAT组的有效率分别为76.3%和80.0%。除放射性食管损伤外（P=0.045），其他急性不良反应两组均无显著性差异(P>0.05)。IMRT组和VMAT组中位OS分别为23.0个月(95%CI：20.4～25.5)和24.3个月(95%CI：21.6～26.9)；PFS分别为15.5个月(95%CI：13.5～17.6)和16.2个月(95% CI：13.5～18.9)；局部复发时间分别为17.1个月(95%CI：14.6～19.6)和18.4个月(95%CI：15.8～21.1)；远处转移时间分别为20.3个月(95%CI：17.5～23.1)和20.8个月(95% CI：17.5～24.1)，差异均无统计学意义(P>0.05)。［结论］ VMAT能够获得与IMRT相同的临床疗效，且可降低放射性食管损伤的发生率。 |

| Abstract：［Purpose］ To compare the clinical effect of step-and-shoot intensity modulated radiotherapy(sIMRT) and volumetric modulated arc therapy(VMAT) for locally advanced non-small cell lung cancer(NSCLC). ［Methods］ The data of 68 cases with advanced NSCLC received IMRT(n=38) or VMAT(n=30) were included and analyzed retrospectively. The short-term and long-term clinical efficacy and acute toxicity between the two groups were evaluated. ［Results］ The total efficacy for IMRT and VMAT group was 76.3% and 80.0% respectively. Except fo radiation esophagitis（P=0.045），there was no significant difference for acute toxicity between the two groups(P>0.05). The median time to OS for IMRT and VMAT group were 23.0 months(95%CI：20.4～25.5) and 24.3 months(95%CI：21.6～26.9) respectively，the median time to PFS was 15.5 months(95%CI：13.5～17.6) and 16.2 months(95%CI：13.5～18.9)，the median time of local-regional recurrence(LRR) was 17.1 months(95%CI：14.6～19.6) and 18.4 months(95%CI：15.8～21.1)，the median time of distant metastasis(DM) was 20.3 months(95%CI：17.5～23.1) and 20.8 months(95%CI：17.5～24.1) respectively， there were no statistical differences between two groups for above 4 indexes(all P>0.05). ［Conclusion］ VMAT achieves the same clinical efficacy as IMRT and can reduce the incidence of radiation esophagitis in locally advanced NSCLC. |
