To evaluate the prognostic value of detailed MRI reports for progress-free survivals (PFS) of patients with Nasopharyngeal Carcinoma (NPC) who underwent intensity modulated radiation therapy (IMRT), we used Cox regression to analyze all the variables of detailed MRI reports and to build a new nomogram for PFS. Our results demonstrated that the new nomogram was more efficient than the American Joint Committee on Cancer (AJCC) 8th staging system. These results indicated that detailed MRI reports could play a more important role in predicting PFS, and some significant factors may be added to improve the current staging system.
