Clinical Trial: Multimodal Evaluation-Guided Surveillance-Intervention With Endoscopic Selective Neck Dissection for Post-Radiotherapy N3 Nasopharyngeal Carcinoma

U.S., July 10 -- ClinicalTrials.gov registry received information related to the study (NCT07692906) titled 'Multimodal Evaluation-Guided Surveillance-Intervention With Endoscopic Selective Neck Dissection for Post-Radiotherapy N3 Nasopharyngeal Carcinoma' on July 03.

Brief Summary: This randomized trial evaluates a multimodal surveillance strategy in nasopharyngeal carcinoma patients with high-risk N3 cervical lymph node involvement after radiotherapy. Patients are assigned to standard follow-up or an enhanced strategy using CEUS, imaging, and EBV DNA for risk assessment. The intervention group uses multimodal evaluation to identify high-risk patients who may undergo multidisciplinary review and selective neck dissection when indicated. T...
