目的回顾性分析肺癌放射治疗后并发急性放射性肺炎的发生率,了解发生的相关因素。方法自2006年1月至2009年12月期间我院收治的146例肺癌患者。常规放射治疗,放射剂量为2Gy/次,1次/d,5次/周,总剂量为50～70Gy。结果急性放射性肺炎发生32例,发生率为21.91%;照射55Gy以下、55～65Gy、65Gy以上的急性放射性肺炎发生率分别为12.2%、20%、33.3%。结论急性放射治疗引起的放射损伤应引起高度重视,放射性肺炎的发生率随常规照射剂量和照射面积的增大而增加。
Objective To retrospectively analyze the incidence of acute radiation pneumonitis after radiotherapy of lung cancer and to understand the related factors. Methods From January 2006 to December 2009 in our hospital admitted to 146 cases of lung cancer patients. Routine radiation therapy, radiation dose 2Gy / time, 1 time / d, 5 times / week, the total dose of 50 ~ 70Gy. Results Acute radiation pneumonitis occurred in 32 cases, the incidence was 21.91%. The incidences of acute radiation pneumonitis below 55Gy, 55 ~ 65Gy and above 65Gy were 12.2%, 20% and 33.3% respectively. Conclusions Radiation injury caused by acute radiation therapy should be given high priority. The incidence of radiation pneumonitis increases with the increase of radiation dose and irradiation area.
