Abstract
BACKGROUND
The optimal treatment for oropharyngeal squamous cell carcinoma (OPSCC) is controversial. There is increasing evidence that, in selected cases, minimally invasive transoral surgery can offer improved functional outcomes, with equivalent oncologic outcomes, compared to chemoradiotherapy.
AIMS
We report the outcomes of transoral laser microsurgery (TLM) for treatment of OPSCC at our institution.
METHODS
Patients with OPSCC undergoing TLM at the South Infirmary Victoria University Hospital, Cork, between 2010 and 2016, were identified from an institutional database. Human papillomavirus (HPV) status was determined by p16 immunohistochemistry. Survival outcomes were analysed using the Kaplan-Meier method. Complications following surgery and gastrostomy tube dependence were evaluated.
RESULTS
The study cohort consisted of 26 patients, with mean age of 56 years (range 29-71). Primary tumours were located in the tonsil (18), base of tongue (4) and other subsites (4). Seventeen cases were p16-positive. Complications included haemorrhage necessitating return to theatre (1) and aspiration pneumonia (1). Four patients underwent tracheostomy, all of whom were successfully decannulated. One patient underwent gastrostomy tube insertion during postoperative radiotherapy. No patient was gastrostomy dependent at latest follow-up. Twenty-two patients received adjuvant treatment, with radiation alone (21) or chemoradiotherapy (2). Mean follow-up was 27 months. Five-year locoregional control was 92% and disease-specific survival was 81%.
CONCLUSIONS
In selected patients with OPSCC, TLM offers excellent functional and survival outcomes, and as such offers an alternative approach to chemoradiotherapy as primary treatment. We compare TLM to other transoral approaches and discuss its potential use in the Irish healthcare system.
