The Use of Lung Dose-Volume Histograms in Predicting Post-radiation Pneumonitis After Non-conventionally Fractionated Radiotherapy for Thoracic Carcinoma

The 15% grade 2-5 pneumonitis rate we document is at the lower end of the spectrum reported in other studies. This suggests that using published data on limiting V20Gy values to reduce the risk of radiation pneumonitis can be extrapolated to planning treatment with non-conventionally fractionated radiotherapy.
