Abstract
The rates of Grade 3 or greater acute esophagitis in patients treated with definitive radiotherapy for lung cancer have been less than 5%. However, the increasing use of concomitant chemoradiotherapy to improve tumor outcomes has been associated with rates of acute esophagitis greater than 15%. The use of intensity-modulated radiation therapy (IMRT) has allowed dose sparing of organs at risk, such as the esophagus, during the treatment planning process. Furthermore, respiratory gating is used to reduce the margin needed for target motion, resulting in smaller treatment volumes.
