[Research Progress on the Protective Effect of Intestinal Flora on Radiation-induced Lung Injury in Thoracic Tumors].

Radiation therapy is one of the main treatment methods for patients with thoracic malignant tumors, which can effectively improve the survival rate of the patients. However, radiation therapy can also cause damage to normal tissues while treating tumors, leading to radiation-induced lung injury such as radiation pneumonia and pulmonary fibrosis. Radiation-induced lung injury is a complex pathophysiological process involving many factors, and its prevention and treatment is one of the difficult problems in the field of radiation medicine. Therefore, the search for sensitive predictors of radiation-induced lung injury can guide clinical radiotherapy and reduce the incidence of radiation-induced lung injury. With the in-depth study of intestinal flora, it can drive immune cells or metabolites to reach lung tissue through the circulatory system to play a role, and participate in the occurrence, development and treatment of lung diseases. At present, there are few studies on intestinal flora and radiation-induced lung injury. Therefore, this paper will comprehensively elaborate the interaction between intestinal flora and radiation-induced lung injury, so as to provide a new direction and strategy for studying the protective effect of intestinal flora on radiation-induced lung injury.
