Review of International (ATA 2015 and ETA 2022) and Russian Recommendations for Radioiodine Therapy in Children with Differentiated Thyroid Cancer

Introduction: Children are not “miniature” adults! Most experts around the world recognize the differences between adult and pediatric thyroid cancer (TC) and emphasize the need for specific guidelines for the pediatric population. In comparing the two guidelines (ATA 2015 and ETA 2022) with each other and with Russian clinical guidelines for the treatment of childhood TC, we found significant differences in determining the tactics of treatment and examination during radioiodine therapy (RIT). The aim of report is to analyze our experience with RIT in children with DTC and to identify the most unresolved issues in the context of current international and Russian recommendations.
