Irradiation of the thoracic esophagus. Prone versus supine treatment positions.
A vast majority of patients with esophageal cancer receive radiation therapy for cure or palliation. Because of the close anatomic proximity of the esophagus to the spinal cord, and unusually long fields used in the irradiation of esophageal cancer, staying within the spinal cord tolerance is crucial. The present investigation shows how this can be achieved by delivering the radiation in prone position.
