Abstract

Background: The purpose of this study was to determine the effect of fraction size on laryngoesophageal dysfunction among patients treated by chemoradiotherapy for laryngeal and hypopharyngeal cancer. Methods: Forty patients underwent chemoradiotherapy for stage III/IV squamous cell carcinomas of the larynx and hypopharynx. Median radiation dose was 70 Gy (range, 69.3-70.4 Gy) with daily fractionation ranging from 2 Gy to 2.2 Gy. Results: When comparing 2 Gy versus >2 Gy daily fractionation, there was no difference in 2-year overall survival (71% vs 72%; p = .68), locoregional control (79% vs 77%; p = .43), or laryngectomy-free survival (60% vs 61%; p = .72). Use of 2 Gy versus >2 Gy fractionation improved laryngoesophageal dysfunction-free survival (2-year estimates, 49% vs 27%; p = .07). Patient-reported voice and swallowing were improved with the former. Conclusion: As the importance of a functional larynx becomes recognized as an endpoint for patients treated by voice preservation, the results of our study help refine treatment guidelines.
