A Pilot Study Assessing Swallowing Function After Transoral Robotic Surgery (TORS) for Head and Neck Cancer
PRIMARY OBJECTIVES:
I. To compare aspiration in oropharyngeal carcinoma patients that underwent transoral
robotic surgery (TORS) vs. chemoradiotherapy (CRT) via an objective instrument, the modified
barium swallow (MBS).
SECONDARY OBJECTIVES:
I. To compare patient-perceived swallowing function of oropharyngeal carcinoma patients that
underwent TORS vs. CRT via a subjective instrument, the M.D. Anderson Dysphagia Inventory
(MDADI) using the total MDADI score.
II. To compare patient-perceived swallowing function of oropharyngeal carcinoma patients
that underwent TORS vs. CRT via a second subjective instrument, the Eating Assessment Tool
(EAT-10) using the total EAT-10 score.
III. To estimate the correlation between the maximum Penetration Aspiration Scale (PAS)
score and MDADI total score in TORS or CRT oropharyngeal carcinoma patients regardless of
treatment modality.
IV. To estimate the correlation between the maximum PAS score and EAT-10 total score in TORS
or CRT oropharyngeal carcinoma patients regardless of treatment modality.
V. To estimate the correlation between MDADI total score and EAT-10 total score in TORS or
CRT oropharyngeal carcinoma patients regardless of treatment modality.
VI. To estimate cervical esophageal stricture diameters after TORS vs. CRT via an objective
instrument, the MBS.
OUTLINE:
Patients undergo the modified barium swallow, comprising swallowing boluses of thin liquid
barium, barium honey, barium pudding, and barium crackers while undergoing fluoroscopic
imaging.

Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic
Dichotomized aspiration, measured via the maximum Penetration-Aspiration Scale (PAS) delineated from the MBS
The maximum PAS score will be dichotomized into aspiration vs no aspiration. The highest (closest to 8 on the PAS scale) PAS score of the 10 swallows will be used for dichotomization. A PAS score of 6 or greater indicates aspiration, while a PAS score of 5 or less is indicative of no aspiration. McNemar's test for correlated proportions will be used to assess the difference between the two treatment groups.
