Background:
Recovery of swallowing in patients treated with trans-oral robotic surgery (TORS) is in general considered as favorable. However, patients afflicted with a secondary primary carcinoma of the head and neck may be more vulnerable to swallowing dysfunctions after trans-oral surgery as a consequence of previous treatments.
Methods:
This is a retrospective monocentric study on patients undergoing TORS for second primary squamous cell carcinoma between 2013 and 2017 (follow-up until June 2021). Swallowing performance was assessed via the functional outcome swallowing scale (FOSS). Also, overall survival (OS), disease-free survival (DS) and disease-specific survival (DSS) were evaluated.
Results:
Eighteen patients (median 62 years) underwent TORS with curative intent for T1-2 oropharyngeal and supraglottic secondary primaries. The average follow-up was of 52 months. All cases were resected R0 using TORS. 84% of patients had a post-treatment FOSS score equal or better upon last follow-up compared with pre-treatment. Only one patient required a percutaneous gastrostomy long term. DSS/DFS/OS at 5 years was 94%, 60%, and 67%, respectively. The main cause of death was metachronous pulmonary neoplasia.
Conclusions:
Our study demonstrates encouraging results in terms of swallowing recovery in patients undergoing TORS for selected secondary primaries of the oropharynx and supraglottic larynx. Further studies into trans-oral surgery for this condition seem therefore warranted. Level of Evidence: Case series; Level 4.
