目的 探讨胸部肿瘤放疗后放射性肺炎的发生因素及治疗方法和预后,方法 收集、分析1997年4月至1998年8月,接受放疗的肺癌、食管癌、胸腺瘤病人285例,发生放射性肺炎30例病人资料。结果 照射剂量和体积是放射性肺炎发生的决定性因素,年纪大、合并上感、有慢支肺气肿病人也易发生放射性肺炎,食管癌放疗合并放射性肺炎较文献报道高,其原因与上述因素有关。结论 对胸部肿瘤放疗应根据病人病期、治疗目的制定出个体化的治疗方案,对肺功能差的病人不要一味要求高剂量,治疗:抗菌素+激素联合治疗,时间应达3～4周。
Objective To investigate the risk factors, treatment methods and prognosis of radiation pneumonitis after radiotherapy for thoracic tumors. Methods: From April 1997 to August 1998, 285 patients with lung cancer, esophageal cancer, and thymoma who received radiotherapy were included. 30 cases of radiation pneumonitis occurred. Patient information. Results The dose and volume of radiation were the decisive factors for the occurrence of radiation pneumonitis. Aging, combined sensation, and chronic broncho- pulmonary emphysema were also prone to radiation pneumonitis. Radiotherapy of esophageal carcinoma combined with radiation pneumonia was higher than that reported in the literature. The reasons were related to the above factors. . Conclusion For radiotherapy of thoracic tumors, individualized treatment plans should be developed according to the patient’s disease stage and therapeutic goals. Patients with poor lung function should not blindly request high doses. Treatment: antibiotic + hormone combination therapy should take 3 to 4 weeks.
