Salvage surgery for recurrent larynx cancer.

Overview

BACKGROUND: Despite advances in treatment, the recurrence rates for laryngeal cancer range from 16% to 40%. METHODS: Patients with recurrent laryngeal cancer treated at Memorial Sloan Kettering (MSK) from 1999 to 2016 were reviewed. Survival outcomes were analyzed. RESULTS: Of 241 patients, 88% were male; the median age was 67 years; 71% had primary glottic tumors. At initial treatment, 72% of patients were seen with early stage disease; primary treatment was radiation (68%), chemoradiation (29%), and surgery (3%). The most common salvage surgery was total laryngectomy (74%). Forty-seven percentage were upstaged at salvage surgery. The 2- and 5-year disease-specific survival (DSS) was 74% and 57%, respectively. Patients with cT4 disease treated with nonsurgical primary management had a 0% 5-year DSS. Independent predictors of DSS were tumor location, perineural invasion, margin, and stage. CONCLUSIONS: Salvage surgery results in acceptable oncologic outcomes. Stage, disease site, perineural invasion, and margins are associated with inferior DSS.
