Abstract 

Respiration-related variations in the distance between the center of mass of gross tumor volume and both esophagus and spinal cord in the transversal plane were on average 3mm (range 1–10mm) and 2mm (range 1–5mm), respectively. Depending on the tumor location and treatment technique, variations might become important for treatment planning.
