Young age is associated with increased rates of residual and recurrent paediatric differentiated thyroid carcinoma

Differentiated thyroid carcinoma is rare in young children. There are conflicting data as to whether disease in this age group differs from that in adolescents and specifically, if it is more aggressive. Current practice guidelines do not differentiate treatment between these groups, but speculate that differences may exist. We sought to compare clinical features, treatment and outcomes between children (<12 years) and adolescents (12‐18 years) with thyroid nodules and thyroid malignancy over a 20‐year period.
