Gastrointestinal Stromal Tumors
Gastrointestinal Stromal Tumors (GISTs) are a rare form of cancer located in the gastrointestinal (GI) tract. More than half of GISTs start in the stomach although many start in the small intestine and other parts of the GI tract. Doctors will look at specific features of a GIST to help predict whether it is likely to grow and spread to other parts of the body. GISTs are evaluated based on the size of the tumor, where it is located in the GI tract, and how fast the tumor cells are dividing (mitotic rate).
The GIST tumors often grow into empty spaces inside the GI tract so they may not cause symptoms until they reach a certain size or are in a certain location. As a result, a small tumor may not cause any symptoms. Common symptoms of GISTs include: include throwing up bright red or dark blood, bleeding into the stool, abdominal pain, a noticeable mass or swelling in the abdomen, nausea or vomiting, loss of appetite and weight loss, and feeling full after eating small amounts of food.
Treatment options depend on a several factors, including the tumor size, the mitotic rate, where the tumor is located in the GI tract, the genetic makeup of the tumor, and if the tumor has spread to other parts of the body. Treatment options include surgery to remove the tumor and targeted therapies with tyrosine kinase inhibitors (TKIs).
