Szczegółowy opis
This is a multicenter, randomized controlled clinical trial evaluating a multimodal evaluation-guided surveillance and intervention strategy in patients with nasopharyngeal carcinoma (NPC) with high-risk N3-stage cervical lymph node involvement after radiotherapy. The study investigates whether combining contrast-enhanced ultrasound (CEUS), conventional imaging (CT/MRI), and Epstein-Barr virus (EBV) DNA monitoring can improve risk stratification, early detection of residual disease, and optimize subsequent treatment decision-making.
Eligible patients will be randomly assigned in a 1:1 ratio to receive either standard post-radiotherapy follow-up or a multimodal evaluation-guided surveillance and intervention strategy. In the control group, patients will receive standard follow-up care according to clinical guidelines. No CEUS or structured multimodal risk stratification will be applied in this group. In the intervention group, patients will undergo an enhanced follow-up strategy based on multimodal evaluation, which integrates CEUS, conventional imaging, and EBV DNA to stratify the risk of residual lymph node disease. Patients identified as high/ very high-risk may receive further multidisciplinary evaluation, and endoscopic selective neck dissection will be performed when indicated.
The primary endpoint is failure-free survival (FFS), defined as the time from randomization to the first occurrence of locoregional recurrence, distant metastasis, or death from any cause, whichever occurs first. Secondary endpoints include overall survival (OS), locoregional relapse-free survival (LRRFS), distant metastasis-free survival (DMFS), and treatment-related safety. Safety will be evaluated according to CTCAE version 5.0. A total of 80 patients will be enrolled across multiple centers in China.
