Different Pattern of Treatment Failure After Chemoradiation Between p16+ and p16− Patients Affected by Oropharyngeal Carcinoma

Head &Neck, EarlyView.
ABSTRACT Background Oropharyngeal cancer (OPC) exhibits distinct clinical behaviors according to HPV/p16 status and smoking exposure. While HPV‐positive OPC generally shows superior survival, differences in recurrence patterns remain unclear. Methods A retrospective multicenter analysis of 674 AJCC VII edition Stage III–IVa/b OPC patients treated with ...
