Gastrointestinal mesenchymal tumors are judged at risk based on the size of the tumor, location of the tumor, nuclear division, and whether it is ruptured. It is usually categorized into 4 levels, very low risk, low risk, medium risk and high risk. The high risk level indicates that the situation is more serious, and it is recommended to consult a doctor in time for regular treatment. 1. Tumor size: usually 2cm, 2~5cm, 5~10cm, 10cm or more, the larger the tumor, the higher the risk. 2. Tumor site: it grows in stomach, small intestine, colon, or outside the gastrointestinal tract, such as mesentery and abdominal cavity. Usually, the risk is higher in the small intestine, colon, and stomach, and lower outside the intestinal tract. 3. Karyorrhexis: according to the pathological examination results after tumor resection, the higher the pathological karyorrhexis, the higher and greater the risk. 4. Whether it is ruptured or not: if the mesenchymal tumor is ruptured, it belongs to high risk, if it is not ruptured, it belongs to low risk. Mesenchymal tumor of gastrointestinal tract is a kind of rare gastric tumor. With the growth of tumor and the increase of schizokurtic item, the tumor may spread and metastasize, thus transforming into malignant growth pattern.
