Key Points

The research aims to enhance the sparing of swallowing structures during treatment planning for head and neck cancer.
Targeted addition of individually contoured constrictors to the existing planning model.
Evaluation of plan quality and organs-at-risk dose levels post-optimization.
Comparison against clinical thresholds for safety.
Significant improvement in sparing swallowing structures observed.
No compromise in overall plan quality noted.
Organs-at-risk doses remained within clinical thresholds.

Abstract

Targeted addition of a small number of cases with individually contoured constrictors to an existing model significantly improved sparing of swallowing structures, without compromising overall plan quality or increasing organs-at-risk (OAR) doses beyond clinical thresholds, highlighting that modest, focused data augmentation can yield clinically meaningful gains.
