Abstract
Despite advances in treatment, the recurrence rates for laryngeal cancer range from 16% to 40%. Patients with recurrent laryngeal cancer treated at Memorial Sloan Kettering (MSK) from 1999 to 2016 were reviewed. Survival outcomes were analyzed. 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. Salvage surgery results in acceptable oncologic outcomes. Stage, disease site, perineural invasion, and margins are associated with inferior DSS.
