胸部肿瘤患者在接受放射治疗过程中,常发生放射性肺损伤(放射性间质性肺炎和肺纤维化),严重影响其生活质量。因此,放射性肺损伤的发病机制及防治研究对于肿瘤的放射治疗具有重要意义。本文就其研究进展进行综述,以期为进一步研究提供理论基础。 Radiation lung injury (radiation-induced interstitial pneumonia and pulmonary fibrosis) often occurs in patients with chest tumors during radiotherapy, which seriously affects their quality of life. Therefore, the pathogenesis of radiation-induced lung injury and prevention and treatment of tumor radiation therapy is of great significance. This article reviews the progress of its research in order to provide a theoretical basis for further research.
