Gastrointestinal stromal tumors (GISTs) are a group of mesenchymal neoplasms originating from precursors of connective tissue cells of the gastrointestinal tract and typically occur in the elderly around the sixth decade of life [1]. The most common sites of GISTs are the stomach (50–70%) and the small intestine (25–35%), whereas they are rarer in colon/rectum (5–10%), mesentery/omentum (7%), and esophagus (< 5%). GISTs originate within the bowel wall and can present with a wide clinical spectrum, thus their prognosis and treatment have not been clearly established, especially for GISTs of the colon.

Most GISTs (69%) are usually identified due to clinical signs and symptoms, such as gastrointestinal bleeding, abdominal pain and palpable abdominal mass. The diagnostic yield of endoscopy as a screening tool for GISTs is quite poor (33%) [2, 3].

Tumor size, mitotic rate, tumor location, kinase mutational status and occurrence of tumor rupture have been proposed to be predictors of...
