Abstract
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract in adults but are very uncommon in children and adolescents. The exact incidence of GIST in this population has not been determined. In the three largest GIST series to date, the percentage of patients below the age of 21 ranged from 0.5% to 2.7%. There is a reported annual incidence of 6.5–14.5 per million cases of GIST overall, while the UK National Registry of Childhood Tumors has reported an annual incidence of 0.02 per million cases of GIST in children below the age of 14 years (Stiller 2007; Benesch et al. 2009).
