title: [Invasive capacity of differentiated thyroid carcinoma in pediatric and adolescent patients].
abstract: 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.
  
  
  CONCLUSIONS
  DTC in pediatric and adolescent patients tend to have a more aggressive pattern, especially in patients younger than 12 years.
