Background:
This ORATOR sub-study evaluated swallowing physiology in patients treated with transoral robotic surgery (TORS) versus radiotherapy (RT) for early-stage oropharynx cancer.
Methods:
Swallowing physiology was evaluated using videofluoroscopy and outcomes were compared across treatment arms and correlated with MDADI scores.
Results:
Of the 68 patients in the ORATOR trial, 21 participated in this sub-study (30.8%), including 15 RT Arm and six TORS Arm patients. Swallowing profiles were not significantly different between the arms. MBSImP pharyngeal scores for RT Arm versus TORS Arm patients were 4.8 (±2.1) versus 4.3 (±1.5) at baseline, 6.2 (±1.2) versus 9.6 (±4.8) at 6 months and 5.9 (±1.8) versus 8.0 (±4.7) at 12 months. MBSImP pharyngeal scores demonstrated weak associations with several MDADI subscales and PAS scores.
Conclusions:
To best describe swallowing outcomes in studies of RT and/or surgery, instrumental swallowing assessments should be strongly considered in addition to quality of life measures.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
