放射性肺炎临床与X线分析

Clinical and X-ray Analysis of Radiation Pneumonia

目的 :分析放射性肺炎相关病因 ,临床与X线表现。方法 :对 12 4例中晚期肺癌进行常规放射治疗。结果 :在临床放疗治疗上 ,放射性肺炎发生共 36例 ,占 2 9% ,且与下列因素有关 :照射剂量是 6 0～ 70GY的有 12例 ,发生率为 85 .7% (P <0 .0 1) ,照射面积 >16 0cm2 的有 2 5例 ,发生率为 71.4% (P <0 .0 1) ,中重度肺功能异常者 11例 ,发生率为 10 0 % (P <0 .0 1)。结论 :放射性肺炎与靶区剂量、照射野的面积成正比关系 ,肺功能中重度异常者必须严格控制照射剂量 ,做到早期预防、早期发现、早期治疗 。

Objective:To analyze the related etiologically factor,clinical and X-ray manifestations of radiation pneumonia. Methods: Routine radiotherapy was performed on 124 patients with lung cancer. Results:The incidence of radiation pneumonia was 29% (36/124).The rate of 12 patients who accepted exposure dose between 60～70GY was 85.7%(P&lt;0.01);for 25 patients whose exposure area was larger than 160 cm 2,the rate was 71.4%(P&lt;0.01);for 11 patients who had moderate or severe abnormal pulmonary function,100% (P&lt;0.01).Conclusion:Radiation pneumonia are directly related with exposure dose and area,Moreover,for the patients who have moderate or severe abnormal pulmonary function, exposure dose must be strictly controlled and finding and therapy of radiation pneumonia earlierly are important to assure the survival quality of patients with lung cancer.
