Objectives: To identify predictors of overall survival (OS) in oropharyngeal squamous cell carcinoma (OPSCC) patients who achieved complete response (CR). Methods: We performed a retrospective study of OPSCC patients who achieved CR from a single academic medical center. Associations between OS, AJCC 8th edition staging system, definitive treatment choice, smoking history, and p16 status were assessed. Results: p16+ status was associated with favorable prognosis for CR (p < 0.001) but not non-CR (p = 0.67) patients. For early stage, p16+ OPSCC patients who achieved CR, surgery + adjuvant radiation (RT) treatment was more durable compared to concurrent chemoradiation (CRT), particularly in smokers. Conclusions: Curative intent treatment choice and smoking history has an impact on the long-term OS of the CR p16+ OPSCC cohort. Prospective studies to define the optimal multi-modality treatment option to manage p16+ OPSCC patients is needed.
