Low-Dose Radiotherapy for Severe COVID-19 Lung Disease—Have Meta-Analyses Accounted for Dose and Timing of Radiotherapy?

Low-dose radiotherapy had historically been used to treat both bacterial and viral pneumonias. In the present day, this is not in use due to the development of antibiotics and other supportive measures as well as a concern regarding late radiation toxicities. COVID-19 presented us with a novel respi...

description Low-dose radiotherapy had historically been used to treat both bacterial and viral pneumonias. In the present day, this is not in use due to the development of antibiotics and other supportive measures as well as a concern regarding late radiation toxicities. COVID-19 presented us with a novel respiratory illness without a strong evidence-based best practice; it was thought, therefore, that there may be a role for low-dose radiotherapy in the absence or failure of a standard treatment. The rationale for this was based around the ability of low-dose radiation to reduce an inflammatory state. We treated two individuals suffering from severe COVID-19 with low-dose whole lung radiotherapy, in the setting of a phase I trial. Both patients improved clinically, biochemically, and radiologically within a matter of days. We discuss why the meta-analyses may not have shown this advantage.
