title: Dose and volume as predictive factors of pulmonary toxicity.
abstract: Dose and volume and their correlation with the development of pulmonary toxicity are among the most widely studied and validated factors in radiotherapy. Most common treatment planning systems allow prompt assessment of Vdose and Mean Lung Dose (MLD). The former represents the percentage of normal lung parenchyma receiving a dose equal to or higher than the established threshold dose; the latter corresponds to the mean dose delivered to the normal lung parenchyma. Most important studies reported on the subject and threhold values recommended for Vdose and MLD are analyzed. The monitoring system of late toxicity used by the authors is presented.
