Objective: Survival of laryngeal cancer is decreasing; thus, optimal treatment selection is paramount. Specifically, T3 disease survival appears similar with surgical or non-surgical management; however, the implications of vocal cord fixation on treatment selection and survival are unknown. This study seeks to determine if surgical treatment of patients with T3M0 laryngeal cancer with vocal cord fixation is associated with superior survival compared to non-surgical treatment. Methods: The National Cancer Database (NCDB) was queried for all T3M0 laryngeal carcinoma cases from 2004 to 2015, whose treatment included surgery or radiation therapy. Cases were stratified by cord fixation status and overall survival was compared using multivariable methods based on surgical versus non-surgical management. Results: Non-surgical management was more common, regardless of cord fixation status (84% in fixed and 79% in mobile). Cord fixation itself did not influence survival; however, surgical management had a significant survival benefit in the fixed cohort (HR = 0.843; 95% CI: 0.738, 0.962). Conclusion: In this large observational cohort study of T3M0 laryngeal cancer, those with fixed cords had superior survival when managed surgically.
