摘要
目的探讨非小细胞肺癌三维适形或调强放疗正常肺V5和V10联合V20评价放射性肺炎(RP)的意义。方法采用三维适形或调强后程加速超分割放疗经病理或细胞学证实初治非小细胞肺癌患者90例,其中Ⅲa期6例、Ⅲb期29例、Ⅳ期55例。放疗剂量61~80 Gy,中位数70 Gy。由剂量体积直方图计算全肺V5、V10、V20、V30、平均肺剂量(MLD),对侧肺V5、V10及同侧肺V30。用CTC3.0标准评估肺损伤。结果 90例患者中发生RP为1级29例、2级23例、3级5例、4级1例、5级1例。全肺V5、V10、V20、对侧肺V10、大体肿瘤体积(GTV)、计划靶体积、射野数目与≥1级RP相关(x2=2.04、2.05、2.01、4.62、6.50、5.61、5.61,P=0.044、0.043、0.047、0.030、0.010、0.020、0.020),全肺V5、V10、V20和V30、MLD与≥2级RP相关(x2=2.05、2.20、2.96、4.96、5.20,P=0.040、0.030、0.000、0.030、0.020)。多因素分析显示GTV与≥1级RP发生相关(x2=4.06,P=0.044),V20与≥2级RP发生相关(x2=9.61,P=0.002)。全肺V5、V10、V20的中位数分别为66%、48%、31%。V20>31%时≥2级RP概率增加,V20>31%+V10>48%+V5>66%时≥2级RP概率增加,V20>31%+V5>66%时≥2级RP概率增加;V20>31%时V10>48%与<48%比较RP概率相似,V20≤31%时V5>66%与<66%、V10>48%与<48%比较RP概率也相似。性别、年龄、临床分期、病理类型、治疗方式、KPS与≥1、2级RP无关。结论肺V5、V10联合V20评价放射性肺炎的发生可能提高预测放射性肺炎的能力。
