Editor-in-Chief, Robert Amdur, MD, discusses a paper from the March 2024 issue of PRO: "Dose-Volume Predictors of Radiation Pneumonitis After Thoracic Hypofractionated Radiation Therapy" (Volume 14 Issue 2, PMID 37984711). This paper suggests V5, V20, and Mean Lung Dose values to minimize grade ≥2 pneumonitis when treating lung cancer with the moderate hypofractionation programs of 60 or 72 Gy at 4 Gy per treatment. The values they propose are lower than those stated in consensus group guidelines.
