Gastrointestinal stromal tumors (GISTs) are relatively rare cancers that originate in the cells of Cajal, which are specialized cells lining the digestive tract responsible for initiating the rhythmic movement that propels food and solid waste through the GI tract.ISTs may be cancerous (malignant) or noncancerous (benign). Malignant GISTs can occur in any part of the gastrointestinal tractâfrom the esophagus to the rectumâbut occur most commonly in the stomach and small intestine.
