Clinical trials

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.
