目的 探讨食管癌放疗后引起放射性肺炎的相关因素.方法 回顾性分析113例放疗后食管癌患者,观察放疗的病变部位、年龄、治疗方案、受照剂量、肺病史和吸烟史与放射性肺炎发生率的关系.结果 发生放射性肺炎16例,其与病变部位、受照剂量及肺病史有关(P＜0.05),与年龄、吸烟及常规放射治疗和IMRT治疗方法关系不大.结论 病变部位、受照剂量,肺病史均会增加放射性肺炎的发生率.%Objective To identify clinical relative factors of radiation pneumonitis in patients with esophagus cancer. Methods A total of 113 patients with esophagus cancer who had received postoperative radiotherapy were retrospectively analysed. The relationship between the incidence of radiation pneumonitis and radiation field, radiation dose, smoking history, age, underlying disease of the lung were observed. Results Of the patients, 16 patients developed radiation pneumonitis. The incidence of radiation pneumonitis was related with radiation field, radiation dose and underlying disease of the lung (P ＜0. 05) , but there were not certain relationships with age, smoking, radiotherapy way. Conclusion Increasing in radiation field and dose, underlying disease of the lung can increase the incidence of radiation pneumonitis in patients with esophagus cancer.
