Dynamic Imaging Grade of Swallowing Toxicity (DIGEST): Scale development and validation

BACKGROUND The National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) is the universal framework for toxicity reporting in oncology trials. The objective of this study was to develop a CTCAE‐compatible modified barium swallow (MBS) grade for the purpose of grading pharyngeal dysphagia as a toxicity endpoint in cooperative‐group organ‐preservation trials for head and neck cancer (HNC). It was hypothesized that a...
