Two‐year prevalence of dysphagia and related outcomes in head and neck cancer survivors: An updated SEER‐Medicare analysis

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.
