Endoscopic surgery compared with intensity-modulated radiotherapy in resectable locally recurrent nasopharyngeal carcinoma: a multicentre, open-label, randomised, controlled, phase 3 trial
This multicentre, open-label, randomized, controlled, phase 3 trial was done in three hospitals in China. The primary endpoint was overall survival, compared between the groups at 3 years. Endoscopic surgery significantly improved overall survival compared with IMRT in patients with resectable locally recurrent NPC.
