Official title
QUantitative Assessment of Swallowing After Radiation (QUASAR): A Longitudinal Comparison of Swallowing Function by Systemic Therapy in Head and Neck Cancer Patients
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
To use novel methods for quantitative analysis of VFSS (videofluoroscopic swallow study, also known as modified barium swallow) to study and compare dysphagia in patients treated for head and neck carcinoma with concurrent radiation therapy and chemotherapy (cisplatin) or targeted therapy (cetuximab) vs. immunotherapy (pembrolizumab, nivolumab, or durvalumab). Our hypothesis is that pharyngeal constriction will be greater (lower ratio) with concurrent immunotherapy compared to chemotherapy, as measured by the pharyngeal constriction ratio (PCR).
