Intermediate Dose-Volume Parameters, Not Low-Dose Bath, Is Superior to Predict Radiation Pneumonitis for Lung Cancer Treated With Intensity-Modulated Radiotherapy

Abstract

This study identified the intermediate dose-volume parameters V20_P and V30_P with better prediction performance for acute RP2 than low-dose metrics V5_G and V5_P. Among all studied predictors, the V30_P had the best discriminating power, and should be considered as a supplement to the traditional dose constraints in lung cancer treated with IMRT.
