Methods Retrospective analysis of consecutive patients treated with chemoradiotherapy between January 2005 and July 2017 was performed with multivariable analysis to explore the impact of smoking status at diagnosis (current/former/never) on overall survival (OS), cancer‐specific survival (CSS) and progression‐free survival (PFS). Results Median follow‐up was 61 months. Four hundred and four patients were included. Current smokers had inferior OS versus never and former smokers [adjusted HR 2.37 (95% CI 1.26–4.45, p < 0.01) and 2.58 (95% CI 1.40–4.73, p < 0.01), respectively] and inferior PFS versus never smokers [adjusted HR 1.83 (95% CI 1.00–3.35, p = 0.04)]. Smoking status did not predict for CSS. Conclusion Detailed smoking behavior should be considered in refining risk groups in HPV‐associated OPC treated with radiotherapy and in future trial design eligibility and stratification.
