Objective: To determine whether return of vocal cord function after treatment of T2b/T3 laryngeal carcinoma is an independent prognostic factor for locoregional recurrence. Study Design: A retrospective review of patients treated with radiation ± chemotherapy between 2000 and 2005 for T2 with vocal cord paresis and T3 laryngeal carcinoma was conducted. Methods: Only those patients obtained from the tumor registry with pre‐and posttreatment video stroboscopies were included. Patients' charts were reviewed for local and regional recurrence after treatment. Fisher's exact test was used to determine significant association between recurrence and possible risk factors. Results: Fourteen patients met the inclusion criterion. Six patients had T2 lesions with vocal cord paresis, and eight patients had T3 lesions. Fifty percent of patients with T2 and 75% of patients with T3 lesions had return of vocal cord function after treatment. Five of 14 patients did not have return of vocal cord function, and of these, 100% had locoregional recurrence. Of the nine patients who had return of vocal cord movement, none of the patients had recurrence. The proportion of recurrence was significantly higher for those whose vocal function did not return compared with the patients whose vocal function returned (100% vs. 0%, P < .01). Conclusion: The immobile vocal cord is associated with a worse prognosis and is therefore factored into the American Joint Commission on Cancer staging for laryngeal tumors. We show that vocal cord immobility is an independent prognostic factor of recurrence even after treatment and can predict treatment failure in T2 and T3 lesions of the larynx.
