Gastrointestinal stromal tumors (GISTs) are rare mesenchymal neoplasms. They arise from the intestinal wall and usually present as subepithelial neoplasms in the stomach and small intestine; however, they can appear anywhere in the gastrointestinal (GI) tract. Most of these tumors have mutations in KIT or platelet-derived growth receptor alpha (PDGFRA), while mutations in succinate dehydrogenase (SDH) or other genes are less frequent. New molecules have shown promising results in the therapy of these tumors.
