Core Tip
Core tip: Surgery is the primary treatment for papillary thyroid microcarcinoma. Prophylactic central lymph node dissection is controversial due to its potential oncologic benefit and side effects. This review provides an overview of previous studies on the predictive factors for lymph node metastases in patients with papillary thyroid microcarcinoma. The most commonly reported factors include age, gender, tumor size and location, multifocality, bilaterality, extrathyroidal extension, and abnormal lymph node found using ultrasound. Prophylactic central neck dissection should be selectively performed only in high-risk patients.
