- Abstract
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. © 2017 Wiley Periodicals, Inc.
