2604.01658 RAD-PNEUM-SBRT v1: A Transparent Framework for Radiation Pneumonitis After Thoracic SBRT
RAD-PNEUM-SBRT v1: We present a pre-validation composite scoring framework for grade >=2 radiation pneumonitis at 12 months in adult patients receiving thoracic SBRT for primary lung cancer or oligometastatic disease. Published literature reports grade >=2 RP 9-28% across SBRT series; lung V20 and mean lung dose remain strongest predictors [Barriger 2012; Palma 2013], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.
