Transaxillary robotic thyroidectomy with modified radical neck dissection versus conventional open surgery for papillary thyroid cancer with lateral lymph node spread

Comparative Study of Transaxillary Robotic Thyroidectomy With Modified Radical Neck Dissection Versus Conventional Open Surgery in Patients With Papillary Thyroid Carcinoma and Lateral Neck Node Metastases: a Prospective Multicenter Randomized Controlled Study

Not applicable Interventional Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University · NCT06623578

This trial tests whether a transaxillary robotic thyroidectomy with modified radical neck dissection can provide similar cancer control but better cosmetic results and recovery than conventional open surgery for adults with papillary thyroid cancer that has spread to nearby neck lymph nodes.

What this trial studies

This comparative interventional study enrolls adults with papillary thyroid carcinoma and ipsilateral lateral cervical lymph node metastasis to receive either a transaxillary robotic thyroidectomy with modified radical neck dissection or conventional open surgery. Eligible patients are 18–70 years old with tumors under 3.0 cm and no extrathyroidal extension by imaging, and surgeons will follow standardized operative and perioperative protocols. Outcomes will include oncologic measures (lymph node clearance, recurrence), surgical complications, cosmetic outcomes, and postoperative quality of life, tracked during inpatient recovery and scheduled follow-up visits. All procedures are performed at Sun Yat-sen Memorial Hospital with long-term follow-up to compare safety and effectiveness between approaches.

Who should consider this trial

Good fit: Adults 18–70 with papillary thyroid carcinoma, ipsilateral lateral cervical lymph node metastasis confirmed by fine-needle aspiration, tumor less than 3.0 cm, and no evidence of extrathyroidal extension are ideal candidates.

Not a fit: Patients with level I or contralateral neck node metastases, enlarged or infiltrative nodes over 2.0 cm, distant metastases, prior neck surgery or radiation, major organ failure, or intolerance to general anesthesia are excluded and unlikely to benefit from the robotic approach in this protocol.

Why it matters

Potential benefit: If successful, the robotic transaxillary approach could offer comparable cancer control with smaller or hidden scars and improved postoperative quality of life.

How similar studies have performed: Previous studies of endoscopy-assisted external cervical approaches have reported similar oncologic outcomes and better cosmetic results compared with open surgery, but transaxillary robotic modified radical neck dissection is less widely studied and remains relatively novel.
