The Role of Prophylactic Central Compartment Neck Dissection in the Management of 2 to 4 cm Papillary Thyroid Carcinoma
Sponsor: Leonardo Rossi
Summary
Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy and is frequently associated with microscopic central neck lymph node metastases, even in the absence of preoperative clinical evidence of nodal involvement (cN0). While prophylactic central compartment neck dissection (pCCND) may improve staging accuracy and potentially reduce disease persistence or recurrence, its routine use remains controversial due to the risk of increased surgical morbidity and potential negligible impact on oncologic outcomes. This prospective randomized study aims to evaluate the oncological and surgical outcomes of cN0 PTC patients with tumors measuring 2 to 4 cm who undergo thyroid surgery with or without pCCND. Patients will be treated according to standard clinical practice with either total thyroidectomy (TT) or thyroid lobectomy (TL), and randomized to receive pCCND (bilateral or ipsilateral, respectively) or not. Patients undergoing TT and those undergoing TL will be analyzed separately in two parallel cohorts. The primary objective is to assess the impact of pCCND on disease persistence or recurrence during long-term follow-up. Secondary objectives include evaluation of surgical complications and the impact of pCCND on pathological staging.

Conditions
Interventions
Total Thyroidectomy + Central Compartment Neck Dissection
Thyroidectomy will be performed with the patient in the supine position with the neck hyperextended. A 3 to 6 cm transverse cervicotomy, two fingers above the sternal notch, will be performed, and the midline will be opened. After the inferior laryngeal nerve and parathyroids are visualized, the thyroidectomy will be achieved. When performed, pCCND will aim at removing the nodes of Level VI, which has been reported to contain the thyroid gland and the adjacent nodes bordered superiorly by the hyoid bone, inferiorly by the brachiocephalic artery, and laterally on each side by the carotid sheaths
Thyroid Lobectomy + ipCCND
Thyroid lobectomy will be performed with the patient in the supine position with the neck hyperextended. A 3 to 6 cm transverse cervicotomy, two fingers above the sternal notch, will be performed, and the midline will be opened. After identification and preservation of the inferior laryngeal nerve and parathyroid glands, thyroid lobectomy will be completed on the affected side. When performed, ipsilateral prophylactic central compartment neck dissection will aim at removing the lymph nodes of Level VI on the operated side, which includes the prelaryngeal, pretracheal, and ipsilateral paratracheal lymph nodes. The central compartment is bordered superiorly by the hyoid bone, inferiorly by the brachiocephalic artery, and laterally by the carotid sheath on the ipsilateral side.
