Accuracy of the Lymph Node Yield in Surgery for Papillary Thyroid Cancer in Children.

This is the first study estimating the necessary LNY for determining nodal positivity in children with cN0 PTC. The high LNY required in small T1 tumors is likely infeasible and should not be pursued. Accuracy increases with lower LNYs for higher T-stages. Our findings can help guide prognosis and treatment for pediatric patients with PTC.
