Objective: To summarize the invasion features of differentiated thyroid carcinoma (DTC) in pediatric and adolescent patients.
Methods: The clinical data of 32 DTC cases (≤18 years old) were retrospectively analyzed for the invasive capacity of DTC in terms of age and gender.
Results: Bilateral (P=0.023), multifoci (P=0.037), and extrathyroid invasions (P=0.041) were more often in patients younger than 12 years old.
Conclusion: DTC in pediatric and adolescent patients tend to have a more aggressive pattern, especially in patients younger than 12 years.
