Nasopharyngeal Carcinoma Patients With Retropharyngeal Lymph Node Metastases: A Minimum Axial Diameter of 6 mm Is a More Accurate Prognostic Predictor Than 5 mm

摘要

OBJECTIVE. The criteria for the diagnosis of metastatic retropharyngeal lymph nodes (RLNs) have not yet been resolved and are not included in the current edition of the American Joint Committee on Cancer (AJCC) staging system (seventh edition) for the staging of nasopharyngeal carcinoma (NPC). The aim of this study was to use MRI to identify an RLN size criterion that can accurately predict prognosis in patients with NPC.
