摘要
目的探讨老年食管癌患者三维适形放疗后放射性肺炎(RP)发生的相关因素。方法回顾性分析行三维适形放疗的90例老年食管癌患者的临床资料及放疗物理参数。结果 15例患者出现RP;RP相关因素有慢性阻塞性肺病(COPD)、再程放疗、放疗剂量、照射野数、肺V5、V10、V15、V20、V25、V30、V40等;性别、吸烟史、糖尿病、临床分期与RP的发生无关。结论 V10、V15、V20、MLD和COPD是RP的独立危险因素。
Objective To study the related factors of radiation pneumonitis（ RP）after three-dimensional conformal radiotherapy in the elder patients with esophageal carcinoma. Methods The clinical data and physical parameters of 90 elder patients with esophageal carcinoma were analyzed. Results RP was observed in the 15 patients;the RP-related factors were chronic obstructive pulmonary disease（ COPD）,secondary radiotherapy,radiation dose, radiation field number,V5 ,V10 ,V15 ,V20 ,V25 ,V30 ,V40 . Gender,smoking,diabetes,clinical stage were not related with RP. Conclusion V10 ,V15 ,V20 ,MLD and COPD are the independent risk factors for RP.
