Multimodal Evaluation-Guided Surveillance-Intervention With Endoscopic Selective Neck Dissection for Post-Radiotherapy N3 Nasopharyngeal Carcinoma
80 participantsStarted 2026-08-01
Plain-language 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. The primary endpoint is failure-free survival (FFS). Secondary endpoints include OS, LRRFS, DMFS, and safety .

Inclusion criteria

. Pathologically confirmed nasopharyngeal non-keratinizing carcinoma (differentiated or undifferentiated, i.e., WHO Type II or III).
. Tumor staged as TanyN3M0 according to the 9th Edition of the American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) staging system.
. ECOG performance status 0-1.
. No previous neck dissection.
. Adequate hematologic, hepatic, and renal function, defined as: white blood cell count ≥4.0 × 10\^9/L, absolute neutrophil count ≥2.0 × 10\^9/L, hemoglobin ≥90 g/L, platelet count ≥100 × 10\^9/L, aspartate aminotransferase and alanine aminotransferase ≤2.5 × the upper limit of normal, and creatinine clearance ≥60 mL/min
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Failure-free Survival
Timeframe: From randomization to disease failure, death, or last follow-up, up to 60 months.
. Written informed consent provided prior to study enrollment
Exclusion criteria
. Ongoing receipt of other antitumor treatment or concurrent participation in another interventional clinical trial.
. Pregnancy or breastfeeding.
. Severe concomitant disease that may, in the investigator's judgment, pose an unacceptable risk or compromise study compliance, including severe cardiac disease, severe pulmonary dysfunction, significant renal disease, or severe psychiatric illness.
. History of another invasive malignancy within 5 years before enrollment, except for adequately treated basal cell carcinoma of the skin, cervical carcinoma in situ, or superficial bladder tumors (Ta, Tis, or T1).
