Trial Identification

Brief Title: NBI Combined With MRI to Guide CTV Optimization in Eccentric Nasopharyngeal Carcinoma

Official Title: Endoscopic NBI Combined With MRI to Guide the Optimization of Clinical Target Volume Delineation in Eccentric Nasopharyngeal Carcinoma

Study ID: NCT06167109

Conditions

Nasopharyngeal Carcinoma by AJCC V8 Stage

Interventions

CTV optimized IMRT

Study Description

Brief Summary: This is a prospective, single-center clinical trial in eccentric nasopharyngeal carcinoma (NPC) patients. The aim of this study is to evaluate the efficacy and safety of NBI combined with MRI-guided optimized CTV compared with conventional CTV, and to compare the radiotherapy-related adverse events and quality of life between the two groups.

Detailed Description: All patients with eccentric nasopharyngeal carcinoma were selected on the basis of MRI findings and NBI endoscopy was performed in these patients. The patients were enrolled if both NBI endoscopy and MRI showed eccentric NPC. Patients with contralateral tissue mucosal abnormalities detected by NBI and confirmed by biopsy were excluded. Then the patients were randomly divided into an experimental group (Optimized CTV) or a control group (Conventional CTV) to evaluate the efficacy and safety of the two groups, as well as radiotherapy-related adverse events.
