Swallowing and communication outcomes following primary transoral robotic surgery for advanced or recurrent oropharyngeal cancer: Case series. (4th July 2022) - Charters, Emma
Abstract: Purpose : Transoral robotic surgery (TORS) is most commonly undertaken as a minimally invasive approach for early staged oropharyngeal cancers (OPC), with good expectations for a functional recovery. A small number of patients, however, require TORS for recurrent or advanced OPC tumours. Their prospects for longer term recovery of communication and swallowing are both unreported and hypothesised to be poorer than the majority of TORS cases. This case-series describes the recovery of swallowing and communication function post-TORS for this unique group of patients. Method : Consecutive recruitment was carried out prospectively at a quaternity oncology referral centre. Participants were aged 18 years and older, with reconstruction involving a free-flap and tracheostomy. Patients were assessed using Fibreoptic Endoscopic Evaluation of Swallowing, and clinician and patient-reported outcomes 12-months post-TORS. Their pre-operative baseline and three-month post-TORS FOIS scores were collated retrospectively. Result : Six participants were recruited over an 18-month period of which three patients underwent TORS for recurrent, and three for advanced OPC. Those with recurrent-OPC did not return to their baseline diet and demonstrated post-swallow silent aspiration of pharyngeal residue. Three of the six were rehabilitated back to their baseline intelligibility (100%). Conclusion : TORS in the recurrent OPC setting appears congruent with high rates of silent aspiration and prolonged reliance on a feeding tube due to oropharyngeal dysphagia, as well as compromised intelligibility. This is the first study that evaluates this instrumentally and provides clinically relevant evidence to inform practice.
