放射性肺炎50例临床分析

【摘要】 目的回顾性分析肺癌、食管癌放射治疗后并发放射性肺炎的发生率,了解发生的相关因素。方法自2003年1月～2007年4月期间我科收治的260例肺癌、食管癌病人。采用直线加速器6～15 MV X线外照射,常规分割,DT4600 CGy-7000 CGy/23～35 F。照射野面积大于120 cm2185例。剂量大于5000 CGy的220例。结果放射性肺炎发生率为19.2%。照射野面积大干120cm2,剂量大于5000 CGy的放射性肺炎发生率分别为24.3%和21.4%。结论放射治疗引起的放射损伤应引起高度重视,照射野面积大,剂量高,放射性肺炎的发生率高。更多还原

【Abstract】 Objective To retrospectively analyze the incidence of the radiation pneumonia(RP)complicated with the radiotherapy of esophagus cancer and lung cancer,and to investigate the correlation between them.Methods The 260 in-patients diagnosed with esophagus cancer and lung cancer in total,from Jan,2003 to April,2007 were proceeded with radiotherapy by the 6-15 MV X Linearity Accelerator through routine segmentation,DT4 600 CGY-7000 CGY/23-25F.The irradiation field area in 185 cases is over 120 cm2,the irradiation doses in 220 cases are higher than 5000 CGY.Results The incidence of RP in all cases is 19.2%, in the cases which the doses are over 5000CGY is 21.4%,in the cases which the radiation field area is over 120 cm2 is 24.3%.Conclusion The radiation-induced pulmonary injury should be more taken care.the wilder the radiation field area and the higher the dose are taken,the more the incidence of the RP takes place.更多还原
