Background: To explore prognostic value of the pre-treatment primary lesion apparent diffusion coefficient (ADC)\nin locoregionally advanced nasopharyngeal carcinoma (LA-NPC).\nMethods: A total of 843 patients with newly diagnosed LA-NPC were enrolled from January 2011 to April 2014 and\ndivided into two groups based on ADC values: the low-ADC group and high-ADC group. The 3-year local relapsefree\nsurvival (LRFS), distant metastasis free survival (DMFS), disease-free survival (DFS) and overall survival (OS) rates\nbetween two groups were compared using Kaplan-Meier curve, and Cox regression analyses were performed to\ntest prognostic value of the pretreatment ADC in LA-NPC.......................
