Clinical and Dosimetric Factors Predicting Grade ≥2 Radiation Pneumonitis after Postoperative Radiotherapy for Patients with Non-Small Cell Lung Carcinoma

Because no standard dose-volume criteria have been established for predicting radiation pneumonitis after postoperative radiotherapy for patients with non-small cell lung cancer, we retrospectively analyzed clinical and dosimetric factors from 199 such patients and identified V10 >30% and V20 >20% as cutoff points for that risk.
