Prognostic Significance of the Number of Metastatic Lymph Nodes to Stratify the Risk of Recurrence

Abstract

Number of metastatic LN was a significant prognostic factor, in addition to the N stage. Therefore, number of metastatic LN must be considered for postoperative staging system to tailor treatment and follow-up recommendations. In addition, patients with ≥2 metastatic LN may benefit from total thyroidectomy and RAI therapy with postoperative follow-up with serum thyroglobulin.
