Deep inspiration breath-hold reduces esophageal dose in spinal stereotactic body radiotherapy: A feasibility study
Year: 2025
Type: article
Abstract: We aimed to assess whether deep inspiration breath-hold (DIBH) could reduce esophageal dose by spinal stereotactic body radiotherapy (SBRT). In 25 patients with thoracic DIBH CT, the vertebral–esophageal distance significantly increased at T2–T9, greatest at Th7 (median 2.1 mm). Simulated SBRT plans showed a strong correlation between distance and esophageal dose, each 1 mm increase reducing 150 cGy. DIBH reduced the esophageal D 0.03 cc dose by a median of 411 cGy while maintaining positional reproducibility within 2 mm. These findings suggest that DIBH may reduce esophageal dose and warrants further study in patients with prior high-dose esophageal exposure.
