Abstract

Background: The long-term effect of concurrent chemoradiation on voice outcomes in the context of non-laryngeal head and neck cancer is not established.

Methods: A prospective, observational study to evaluate the voice quality in disease-free patients receiving concurrent chemoradiation for advanced non-laryngeal squamous cell carcinoma of the upper aerodigestive tract. Voice assessment occurred at four distinct time-points: pretreatment, 3, 12 and 92.6 months (mean) post-treatment in 34, 21 and nine patients, respectively. The authors used a combination of subjective (VoiSS questionnaire), expert rater-assessed (GRBAS scale) and acoustic analysis of the fundamental frequency to assess voice outcomes. Ethical approval was obtained from the United Kingdom National Research Ethics Service.

Results: Both the VoiSS impairment and GRBAS domains continued to deteriorate over time from pre-treatment to 92.6 months post-treatment (P = 0.03). There was a strong correlation between increase in total VoiSS and GRBAS scores (r = 0.93). Acoustic analysis demonstrated no statistically significant variation in fundamental frequency.

Conclusion: Radiation therapy for advanced non-laryngeal head and neck has a significant, deleterious effect on voice, which is apparent up to eight years post-treatment.
