Recent advances in science and clinical studies of pediatric DTC, particularly in papillary thyroid carcinoma, the predominant subtype, now form the basis of emerging paradigms and revised guidelines. The potential of malignancy in thyroid nodules, as defined by current ultrasound risk stratification systems, has been evaluated in pediatric patients, enabling evidence-based indication for fine-needle aspiration biopsy. Observational studies comparing the effect of different interventions on prognosis, complications, and quality of life, challenge traditional surgical approaches in favor of potentially less extensive initial resection. Recognition of distinct underlying oncogenic drivers has not only paved the way for discoveries in the biology of pediatric thyroid cancer but has also advanced the era of targeted systemic therapy for progressive and metastatic pediatric DTC. Certain genome alterations, particularly oncogenic gene fusions that are more common in pediatric DTC, can now be targeted with small-molecule inhibitors, offering more effective therapy for metastatic disease with fewer and less severe adverse effects.

Insulin resistance is a key contributor to the pathophysiology of those conditions, and the physiological reduction in insulin sensitivity during puberty further contributes to their pathogenesis in youth. However, insulin sensitivity improves after puberty, leading to spontaneous normalization of glucose metabolism in most individuals and complicating the concept of prediabetes. Therefore, general population screening for diabetes in youth is not recommended except in certain populations with high prevalence. When prediabetes is identified, lifestyle modification remains the primary intervention because pharmacologic treatments have yet to show efficacy in youth.
