Salvage Transoral Laser Supraglottic Laryngectomy after Radiation Failure: A Report of Seven Cases

Abstract

We evaluated the oncological and functional outcomes of salvage transoral laser supraglottic laryngectomy after radiation failure. In addition, we demonstrated the usefulness of laser surgery in patients with recurrent supraglottic cancer. Between December 1999 and May 2011,7 patients (6 men and 1 woman) underwent transoral laser supraglottic laryngectomy after radiation failure. We conducted 4 different types of endoscopic supraglottic laryngectomy. In the cases with lymph node metastasis, we performed neck dissection at the time of laser surgery. All patients had recurrent squamous cell carcinoma confirmed on the surgical specimen. Two patients were classified as having T1 disease, 2 as having T2 disease, and 3 as having T3 disease with preepiglottic space involvement. The 2- and 5-year overall survival rates were 85.7% and 68.6%, respectively. There was a recurrence at 8 months of followup after laser surgery in 1 patient; he underwent successful salvage total laryngectomy. The ultimate local control rate was 100%, and the laryngeal preservation rate was 85.7%. The hospitalization times ranged from 2 to 32 days (mean, 15.6 days). The mean decannulation time was 10.7 days (range, 5 to 30 days). All patients started oral feeding within 1 to 3 days after surgery. Salvage transoral laser supraglottic laryngectomy following radiation failure seems a feasible and oncologically safe procedure in recurrent supraglottic cancers ranging from T1 to selected T3 with minimal preepiglottic space involvement. It can be an option for minimally invasive organ preservation surgery with lesser morbidity for recurrent supraglottic cancer.
