RECRUITINGPhase 3INTERVENTIONAL

Selective Neck Dissection Versus Modified Neck Dissection in PTC

Tracer Navigated Selective Neck Dissection Versus Modified Neck Dissection in Papillary Thyroid Cancer With Limited Lymph Node Metastasis in the Lateral Neck: A Randomized, Noninferiority Phase III Trial

Selective Neck Dissection Versus Modified Neck Dissection in PTC (NCT06554652) is a Phase 3 interventional studying Thyroid Cancer, sponsored by Fudan University. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This study is a phase III, randomized controlled, open label non inferiority study. Patients who meet the inclusion criteria are randomly assigned 1:1 to either the experimental group (selective neck dissection) or the control group (modified neck dissection), with LRFS as the primary endpoint. The aim of the study is to evaluate the safety of selective neck dissection in papillary carcinoma with limited number of lymph node metastases in the lateral neck, and the quality of life compared with modified neck dissection.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Thyroid Cancer, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 250 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Thyroid Cancer subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - Pathologically confirmed PTC; - Age range: 14-80 years old; - Preoperative fine needle aspiration confirms lymph node metastasis in the lateral neck - Ultrasound and CT suggest that metastatic/suspected metastatic lymph nodes are limited to compartment IV, with 1-2 lymph node metastases and \<1cm in short diameter. The lymph nodes have no central necrosis, liquefaction, peripheral enhancement, or disappearance of adjacent fat spaces (predicting unobstructed lymphatic vessels); - Thyroid tumors without extra thyroidal extension; - Enough thyroid volume to inject tracer. Who Should NOT Join This Trial: - Previous neck surgery; - Bilateral neck lymph node dissection; - Distant metastases; - High risk pathological subtypes or the presence of other high-risk factors for recurrence; - Previous treatment for thyroid cancer other than endocrine therapy; - The patient is unable to cooperate with follow-up. Always talk to your doctor about whether this trial is right for you.

Treatments Being Tested

PROCEDURE

Lymph node tracer navigated selective neck dissection

Selective lateral lymph node dissection (after injection of tracer, lymph nodes in compartment III-IV are dissected; if there is dyed lymph node in compartment IIA, then IIA is dissected).

PROCEDURE

Modified neck dissection

Lymph nodes in compartment IIA, IIB, III, IV, VB are dissected.

Bring the printable summary of this trial — including the NCT ID (NCT06554652), the sponsor (Fudan University), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Frequently Asked Questions

What is the NCT06554652 clinical trial studying?

This study is a phase III, randomized controlled, open label non inferiority study. Patients who meet the inclusion criteria are randomly assigned 1:1 to either the experimental group (selective neck dissection) or the control group (modified neck dissection), with LRFS as the primary endpoint. The aim of the study is to evaluate the safety of selective neck dissection in papillary carcinoma with limited number of lymph node metastases in the lateral neck, and the quality of life compared with modified neck dissection. The full protocol is registered on ClinicalTrials.gov and includes the primary outcome measures, eligibility criteria, and study endpoints.

Who can participate in NCT06554652?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT06554652?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
