PH-0042: Aspiration related OARs are relevant predictors of silent aspiration after (chemo)radiation

Late aspiration, potentially leading to pneumonia, is one of the most hazardou scomplications after (chemo)radiation ((CH)RT) for head and neck cancer. Videofluoroscopy(VF) is the golden standard of objective dysphagia evaluation, detecting (silent) swallowing disorders and the Penetration Aspiration Scale (PAS) is a validated VF-based, 8-point tool for aspiration assessment.(CH)RT is known to be associated with increased risk of aspiration. The purpose of this analysis was to identify the best predictors of RT-induced silent aspiration captured on VF.
