Prognostic Value and Staging Classification of Retropharyngeal Lymph Node Metastasis in Nasopharyngeal Carcinoma Patients Treated with Intensity-modulated Radiotherapy

The development of intensity-modulated radiotherapy  has revolutionized the management of nasopharyngeal carcinoma . The purpose of this study was to evaluate the prognostic value and classification of TNM stage system for retropharyngeal lymph node  metastasis in NPC in the IMRT era

调强放射治疗（Intensity-Modulated Radiotherapy, IMRT）的发展彻底革新了鼻咽癌（Nasopharyngeal Carcinoma, NPC）的临床诊疗管理模式。本研究旨在评估IMRT时代，针对鼻咽癌咽后淋巴结转移（retropharyngeal lymph node metastasis）的TNM分期系统（TNM Staging System）的预后价值与分类效能。
