OBJECTIVES: Vocal cord fixation is one of the main upstaging features of laryngeal cancer. In our previously conducted retrospective study, vocal cord (VC) mobility restoration after chemoradiotherapy was a favorable prognostic variable. In this prospective study, we examined the significance of VC mobility restoration after definitive treatment as a prognostic variable.
METHODS: In this prospective cohort study, we enrolled 30 patients with squamous cell carcinoma of the larynx with VC impairment/fixation (T2/3, T4a) who underwent definitive chemoradiotherapy with complete response. Video laryngoscopy before and at 3 months after treatment was used to evaluate VC mobility. The primary endpoint of the study was the local recurrence-free probability. Secondary endpoints included recurrence-free probability, disease-specific survival (DSS), and overall survival (OS).
RESULTS: The median age of patients was 62 years (IQR 54-67). The primary subsites were the glottis (n = 13) and supraglottis (n = 14). After treatment, 18 (60%) patients had a full recovery of VC mobility, and 12 (40%) patients' VCs were fixed or impaired. Five-year local recurrence-free probability was worse in the VC-impaired group compared to a group with restored VC mobility (46% vs. 85%, p = 0.012). Recurrence-free probability, OS, and DSS differences were not statistically significant in both groups. VC mobility restoration predicted local recurrence-free probability on univariable analysis (HR 6.15, 95% CI 1.23-30.6).
CONCLUSION: In this prospective study, we show that the absence of VC mobility restoration is associated with worse local recurrence-free probability after definitive laryngeal preservation treatment. Patients with persistent vocal cord immobility warrant closer follow-up to detect recurrence early.
