GISTs are usually found in adults between ages 40 and 70; rarely, children and young adults develop these tumors.
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.leevecÂ® (imatinib mesylate) in the treatment of GIST: Gleevec is a type of targeted therapy that works by inhibiting a protein called tyrosine kinase. Tyrosine kinase is overproduced in GIST cells and is responsible for helping the cancer cells survive and grow.
