Song E, Ahn J, Song DE, et al. - In 571 individuals who had thyroid lobectomy for 1–4 cm-sized papillary thyroid carcinoma, researchers conducted this retrospective cohort study to analyze the risk of recurrence according to the present American Thyroid Association (ATA) risk stratification system. The results of this study reveal that risk stratification based on lymph node metastases alone was more reasonable to predict structural persistence/recurrence after lobectomy than that based on the overall ATA criteria. Considering the extranodal extension status, individuals with a high risk of recurrence can be selected to minimize further treatments.
