OBJECTIVE: Chemoradiotherapy (cRT) and total laryngectomy (TL) are acceptable treatments for locally advanced laryngeal squamous cell carcinoma (LSSC). We aimed to compare the outcomes in patients receiving full-dose treatment.
METHODS: We identified 11,237 patients in the National Cancer Database treated 2004 to 2015 for T3-4N0-3 LSCC with either TL (with 60 to 80 Gy of adjuvant RT) or cRT (70 to 80 Gy). We evaluated differences in overall survival (OS) using Kaplan-Meier and Cox proportional hazards modeling.
RESULTS: For patients with T3 disease, there was no difference in OS regardless of N stage (N0: hazard ratio [HR]=0.94, P=0.38; N+: HR=0.92, P=0.19). TL was associated with improved OS in patients with T4 disease (N0: HR=1.39, P<0.001; N+: HR=1.22, P=0.001).
CONCLUSION: In patients who receive optimal therapy, both TL and cRT offer similar outcomes in T3 but not T4a disease.
