SummaryPurposeHPV status and smoking history stratifies patients into 3 distinct risk groups for survival following definitive chemoradiotherapy. Local-regional recurrences are common patterns of failure across all 3 risk-groups. SBRT ± cetuximab has emerged as a promising salvage strategy for unresectable locally-recurrent, previously-irradiated head-and-neck cancer (rHNC) relative to conventional re-irradiation ± chemotherapy. However the influence of HPV and smoking remains unknown in the setting of re-irradiation.Methods/materialsPatients (n = 30) with rHNC of the oropharynx salvaged with SBRT ± cetuximab from August 2002 through August 2013 were retrospectively reviewed; HPV status was determined based on p16 staining of primary pathology.ResultsAt a median follow-up of 10 months for surviving patients, the mean overall survival for all patients was 12.6 months. HPV positivity was a significant predictor of overall survival (13.6 vs. 6.88 months, p = 0.024), while smoking status did not significantly impact overall survival (p = 0.707).ConclusionHPV status remains a significant predictor of overall survival in the re-irradiation setting with HPV positive rHNC demonstrating superior overall survival following salvage SBRT ± cetuximab.
