BACKGROUND: The functional outcome after the treatment of laryngeal cancer is tightly related to the quality of life of affected patients. The aim of this study is to describe the long-term morbidity and functional outcomes associated with the different treatment modalities for laryngeal cancer.
METHODS: Retrospective chart review of 477 patients undergoing curatively intended treatment for laryngeal cancer at our tertiary referral center from 2001 to 2014: Details on patient and disease characteristics, diagnostics and treatment related functional outcomes were analyzed.
RESULTS: With a median follow-up of 51 months, the crude rate of functional larynx preservation was 74.6%. Radiotherapy +/- chemotherapy was the dominant treatment modality (n = 359-75.3%), whereas 24.7% (n = 118) underwent primary surgery, with 58.5% (69) receiving adjuvant treatment. The 5-year laryngectomy-free survival was 57% (95% CI, 48-66%) after surgery vs. 69% (95% CI, 64-75%) after chemoradiotherapy (p < 0.01). In stage III-IVB, these rates were 26% (95% CI, 16-39%) vs. 47% (95% CI, 36-59%), respectively (p < 0.01). Aspiration occurred in 7%, tracheostomy was necessary in 19.8% and feeding tube placement in 25.4%. Feeding tube and tracheostomy necessity was higher in the initially surgically treated group. Primary surgery (HR: 1.67, 95% CI: 1.19-2.32; p < 0.01), stage III-IVB (HR: 4.07, 95% CI: 2.97-5.60; p < 0.01) and tumor recurrence (HR: 3.83, 95% CI: 2.79-5.28; p < 0.01) remained as adverse factors for laryngectomy-free survival.
CONCLUSIONS: Preserving the laryngeal function after cancer treatment is challenging. Advanced tumor stages, primary surgery and recurrence are related to a poor functional outcome. Therefore, the criteria for initial decision-making needs to be further refined.
