Gastrointestinal stromal tumor (GIST) is a rare type of cancer that begins in the cells of the gastrointestinal tract. GISTs can occur anywhere in the digestive system, but they most commonly occur in the stomach or small intestine.
GISTs are caused by mutations in certain genes that control cell growth and division. These mutations cause cells in the gastrointestinal tract to grow and divide uncontrollably, forming a tumor. Most GISTs are noncancerous (benign), but some can become cancerous (malignant).
The symptoms of GISTs can vary depending on the location and size of the tumor. Some people with GISTs may have no symptoms, while others may experience:
Diagnosis of GISTs typically involves imaging tests, such as CT scans or MRIs, as well as a biopsy to confirm the presence of cancerous cells. Treatment for GISTs depends on the size, location, and stage of the tumor. Treatment options may include:
The prognosis for GISTs can vary depending on the size and location of the tumor, as well as whether it has spread to other parts of the body. GISTs that are caught early and treated aggressively have a better prognosis than those that have spread or are not responsive to treatment.
