Summary
Brief summary (as posted)
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).

Inclusion Criteria: * Biopsy-proven, un-resected invasive carcinoma of the head and neck. * Treated with definitive RT and concurrent systemic therapy or treated within the past 4-24 months * Concurrent systemic therapy with Cisplatin, Cetuximab or immunotherapy. * Age ≥ 18 * Able to understand and willing to sign a written informed consent. Exclusion Criteria: * Prior radiotherapy that would result in overlap of planned radiation therapy fields. * Prior systemic chemotherapy, unless as part of the coordinated plan of care for the treatment of the carcinoma (e.g., induction/neoadjuvant chemotherapy is allowed) * Planned adjuvant (i.e., following definitive chemoradiotherapy) chemotherapy or surgery
