Abstract
Background: Knowledge about prognostic factors in surgically treated patients with oropharyngeal squamous cell carcinoma (SCC) is limited. The purpose of this study was to identify influential factors on survival in a large cohort of patients with surgically treated oropharyngeal SCC. Methods: Retrospective analysis of survival estimates in patients with surgically treated oropharyngeal SCC using tumoral positivity for human papillomavirus (HPV) and risk-of-death categories according to a study from 2010 as stratification factors. Results: The 5-year overall survival (OS) and disease-specific survival (DSS) rates after surgery alone were higher in HPV-associated oropharyngeal SCC (OS 80% vs 62%; P =.01; DSS 92% vs 76%; P =.03). Patients in the low-risk category had higher survival rates (OS 91%; DSS 99%) than patients in the intermediate-risk group (OS 63%; DSS 83%), and high-risk group (OS 61%; DSS 75%). Conclusion: Nonsmokers with HPV-positive oropharyngeal SCC have a better prognosis than smokers with HPV-positive oropharyngeal SCC and also than patients with HPV-negative tumors when treated by surgery alone.
