Role of cell fate regulation by ionizing radiation in radiation-induced lung injury and its therapeutic progress / 西安交通大学学报(医学版)

ABSTRACT

Radiation induced lung injury (RILI) is a common complication after radiation therapy of breast tumors and bone marrow transplantation pretreatment, and it is a critical limiting factor of radiotherapy doses in patients. Once RILI progresses to the radiation-induced pulmonary fibrosis stage, it seriously reduces the patient’s quality of life, while causing the patient’s respiratory failure and eventually leading to death. Ionizing radiation (IR) can induce cell injuries, including apoptosis, epithelial-mesenchymal transition, senescence, pyroptosis and ferroptosis, and these injuries can play an important role in the occurrence and development of radioactive lung injury. Starting from discussion of the occurrence of different forms of injury in different cells after IR stimulation, this review summarizes the pathogenesis of RILI and its clinical prevention and treatment.
