Application of Endoscopic Selective Neck Dissection Under Multimodal Assessment for Residual Cervical Lymph Nodes in N3 Nasopharyngeal Carcinoma After Radiotherapy
2 de junho de 2026 atualizado por: Guiquan Zhu
A Phase 1 Trial of Multimodal Evaluation-Guided Surveillance-Intervention With Endoscopic Selective Neck Dissection for N3 Nasopharyngeal Carcinoma After Radiotherapy
The goal of this phase I clinical trial is to learn whether a multimodal follow-up evaluation combined with endoscopic selective neck dissection (ESND) is safe and feasible in patients with newly diagnosed N3 nasopharyngeal carcinoma.
The main questions it aims to answer are:
- Is the multimodal evaluation-guided surveillance-intervention approach safe for patients?
- Is this approach feasible for identifying and managing residual cervical lymph nodes after radiotherapy? Participants will receive standard chemoradiotherapy. After treatment, they will undergo follow-up evaluation using clinical assessment, conventional imaging, Epstein-Barr virus DNA testing, and contrast-enhanced ultrasound. Participants with clinically suspicious residual cervical lymph nodes identified by multimodal evaluation and eligible for surgery underwent endoscopic selective neck dissection.

Descrição detalhada
Patients with N3 nasopharyngeal carcinoma remain at risk of residual cervical lymph nodes after radiotherapy.
Conventional imaging may have difficulty distinguishing viable residual tumor from post-radiotherapy edema, fibrosis, scarring, or inflammation.
Contrast-enhanced ultrasound (CEUS) provides information on lymph node microvascular perfusion and may complement routine follow-up assessment.
For patients with suspected residual cervical lymph nodes, neck dissection is an established salvage treatment option.
Endoscopic selective neck dissection (ESND) is a minimally invasive surgical approach based on the principles of selective neck dissection and may reduce surgical trauma.
This prospective, single-center, single-arm phase I study enrolled patients with pathologically confirmed N3 nasopharyngeal carcinoma.
After completion of radiotherapy, participants underwent multimodal cervical lymph node follow-up evaluation, including clinical assessment, conventional imaging, Epstein-Barr virus DNA testing, and CEUS.
During follow-up, participants with suspicious residual cervical lymph nodes identified by multimodal evaluation and suitable for surgery underwent ESND.
Participants were followed for adverse events, postoperative complications, disease progression, locoregional recurrence, distant metastasis, and survival outcomes.
The main purpose of this study is to evaluate the safety and feasibility of this multimodal evaluation-guided surveillance-intervention strategy.
