Abstract

Abstract: Background: Concurrent chemoradiotherapy (CRT) became the standard of care for locoregionally advanced head and neck cancers based on clinical trials but its effectiveness at the community level is not reported. Methods: We conducted a population‐based comparative effectiveness study of all 571 patients with oropharyngeal cancer in Ontario Canada (2003–2004) that describes the patients and the treatments and compares concurrent CRT to radiotherapy (RT) alone. Results: When comparing the outcomes (CRT vs RT) for all patients or patients eligible for either treatment, for patients of centers with the "higher use" of CRT to patients of the 'lower use' centers and comparing all centers, we found no overall or disease‐specific advantage to CRT over RT alone. There was also no difference in recurrence‐free survival, pattern of recurrences, or distant control. Conclusion: In Ontario (2003–2004), in daily clinical practice, the addition of concurrent CRT to RT had little impact on survival in patients with oropharyngeal carcinoma. © 2014 Wiley Periodicals, Inc.
