Clinical characteristics of post-radiation nasopharyngeal necrosis. A Typical endoscopic and magnetic resonance imaging manifestations of post-radiation nasopharyngeal necrosis (PRNN), along with the associated symptoms and complications. B Incidences of PRNN following re-radiotherapy in 625 patients with locally recurrent nasopharyngeal carcinoma (LRNPC) recruited from the Sun Yat-sen University Cancer Centre. Most events occurred within 1 year of re-radiotherapy. C Kaplan–Meier curve showing that PRNN significantly impaired overall survival (OS). D PRNN and massive bleeding are leading causes of death for re-irradiated patients with LRNPC
