Abstract: BACKGROUND: The aim of the study was to examine prevalence of dysphagia at the population level in head and neck cancer (HNC) survivors. METHODS: Surveillance, Epidemiology, and End Results-Medicare claims among 16 194 patients with HNC (2002-2011) were analyzed to estimate 2-year prevalence of dysphagia, stricture, and aspiration pneumonia, and derive treatment- and site-specific estimates. RESULTS: Prevalence of dysphagia, stricture, pneumonia, and aspiration pneumonia was 45.3% (95% confidence interval [CI]: 44.5-46.1), 10.2% (95% CI: 9.7-10.7), 26.3% (95% CI: 25.6-26.9), and 8.6% (95% CI: 8.2-9.1), respectively. Dysphagia increased by 11.7% over the 10-year period (P < .001). Prevalence was highest after chemoradiation and multimodality therapy. CONCLUSION: Comparing to published rates using similar methodology the preceding decade (1992-1999), prevalence of dysphagia based on claims data was similar in 2002-2011 in this study. These results suggest persistence of dysphagia as a highly prevalent morbidity, even in the decade in which highly conformal radiotherapy and minimally invasive surgeries were popularized.
