Proposed Lymph Node Staging System Using the International Consensus Guidelines for Lymph Node Levels Is Predictive for Nasopharyngeal Carcinoma Patients From Endemic Areas Treated With Intensity Modulated Radiation Therapy

摘要

To remain relevant, the nasopharyngeal carcinoma (NPC) staging system should be re-evaluated in light of advances in detection and treatment technologies. Therefore, we performed a retrospective study of 749 NPC patients and proposed a new N staging system based on complete MRI and intensity modulated radiation therapy data. Furthermore, the International Consensus Guidelines for lymph node
