Outcomes of salvage surgery for the oropharynx and larynx: a contemporary experience in a UK Cancer Centre.

ABSTRACT

INTRODUCTION: The purpose of this study was to review our recent experience of salvage surgery, comparing larynx and oropharynx recurrence patterns. METHODS: A single centre, retrospective review of salvage surgery for recurrent head and neck cancer including patients between 2008 and 2016. RESULTS: 61 patients were identified, 36 underwent salvage laryngectomy and 25 received oropharyngeal resections. The median overall survival of oropharyngeal recurrent tumors was 26 months (95% CI 15-118 months) and for laryngeal tumors was 23 months (95% CI 11-38 months), p = 0.1008. There was a significant overall survival benefit in patients with negative resection margin. The median survival in the negative margin group was 38 months (95% CI 25-108 months) compared to the positive margin group, 9 months (95% CI 5-15 months), p < 0.0001. CONCLUSION: Survival results following surgical salvage in the larynx and oropharynx appear to be similarly poor. Those patients with clear margins appear to have a significantly better prognosis.
