Gastrointestinal stromal tumor (GIST) is the most common sarcoma of the gastrointestinal tract. It most often comes from the stomach or small intestine. There are three factors affecting the prognosis of people with GIST, including tumor size, location, and cellular division. Firstly, Patients whose tumors are 10 cm or greater in size have a high chance of developing tumor recurrence, while people whose tumors are less than 2 cm are much more likely to be cured by surgical resection. As for people with tumors between 2 and 10 cm, the risk of recurrence after surgery is intermediate. Secondly, the location of a GIST is believed to influence the result. If the GIST is located in your stomach, you will be much better than people with small intestine GIST. In addition, patients with a mitotic rate (the rate of cellular division, which is determined by examining the tumor under a microscope) of 5 or greater per 50 high power microscopic fields have a higher chance of tumor recurrence after removal of a GIST. Last but not the least, if the tumor spread is detected, the prognosis of these patients will be worse. If you need more information about GIST, please consult your doctor.
