Hyperbaric Oxygen in the Prevention of Radiation Pneumonitis

Summary

Radiotherapy is one of the important treatments to improve the survival rate of breast cancer patients, but also has the risk of radiation lung injury, which can develop into pulmonary fibrosis. Hyperbaric oxygen can improve the tissue after radiation by promoting the function of vascular endothelial cells and fibroblasts, and reducing the secretion of inflammatory factors, thereby inhibiting the process of fibrosis and fiber atrophy after radiotherapy, and promoting tissue repair. Therefore, it has the potential value of treating chronic radiation injury. We aim to investigate whether hyperbaric oxygen treatment can reduce the incidence of radiation pneumonia and improve patients' quality of life, and to evaluate its safety and the impact on the patients' long-term survival outcomes.
