Clinical Risk Factors Associated with Cervical Lymph Node Recurrence in Papillary Thyroid Carcinoma

Abstract

Considering the low incidence of regional lymph node recurrence and the levels with frequent regional recurrence in patients without lymph node metastasis, elective neck dissection in all cases of total thyroidectomy may be immoderate. However, if any risk factors for regional recurrence, including large tumor size, presence of extrathyroid spread, high T stage, and presence of lymph node metastasis, are detected by preoperative and intraoperative evaluation, a systematic compartment-oriented lymphadenectomy should be considered because of the high possibility of regional recurrence.
