Abstract: Introduction: Although nasopharyngeal carcinoma (NPC) is rare in many parts of the world, it is endemic in certain regions, especially in Southeast AsiaParticularly Bangladesh. Radiotherapy is the mainstay treatment for NPC. In recent years, IMRT has gradually replaced conventional radiation therapy as the main radiotherapy technology used to treat NPC.Objective: The aim of this study was to explore the patterns of retropharyngeal lymph node (RLN) metastasis innasopharyngeal carcinoma (NPC) and their impact on the clinical target volume (CTV) delineation in radiotherapy. Methods: A total of 190 patients with untreated, nonmetastatic NPC received MRI scans of the nasopharynx and neck before treatment at the Department of Oncology, Enam Medical College.....
