Papillary thyroid cancer (PTC) is the most common thyroid tumor in childhood and adolescence. Most of these patients are referred with locally advanced and/or distant disease at the moment of diagnosis. Whenever is possible, these patients should be offered a total thyroidectomy and radioiodine remnant ablation.

RET/PTC fusions were found to be associated with an increased risk of invasive disease. The aims of our study were to analyze...
