Gastrointestinal stromal tumors
Gastrointestinal Stromal Tumors (GIST) are uncommon tumors that develop in the digestive tract, most frequently in the stomach or small intestine. They arise from specialized cells involved in regulating movement through the gastrointestinal system. GISTs can range from slow-growing tumors to more aggressive forms, making accurate diagnosis and appropriate treatment essential.
Our experienced gastrointestinal surgical team provides comprehensive evaluation and individualized treatment for GIST, including advanced minimally invasive surgery when appropriate.
What Is a Gastrointestinal Stromal Tumor?
GIST is a type of soft tissue tumor that develops in the gastrointestinal tract. Unlike many other gastrointestinal cancers, GISTs arise from specialized cells known as interstitial cells of Cajal or related precursor cells.
They can occur anywhere along the digestive tract but are most commonly found in:
- Stomach
- Small Intestine
- Colon
- Rectum
- Esophagus
The behavior of a GIST depends on factors such as its size, location, mitotic rate, and other pathological characteristics.
Symptoms of GIST
Some GISTs are discovered incidentally during imaging or endoscopy and may not cause symptoms. When symptoms occur, they can include:
