Gastric mesenchymal tumors are not cancerous, but are generally considered tumors with malignant potential. Gastric mesenchymal tumors, also known as gastrointestinal mesenchymal tumors, are the most common mesenchymal tumors of the human digestive tract, which originate from mesenchymal cells in the gastrointestinal tract that are oriented for differentiation. Molecularly, gastric mesenchymal tumors are characterized by mutations in the c-kit gene, which leads to continuous activation of the tyrosine kinase receptor in the body, ultimately leading to the proliferation of tumor cells. In the clinic, gastric mesenchymal tumor can be treated by surgery, and after the surgery, it is necessary to choose whether to give imatinib mesylate for treatment according to the actual situation of the patient. When patients have symptoms of gastric mesenchymal tumor, they need to go to the hospital for treatment as soon as possible to avoid delaying the condition. Please strictly follow the doctor’s instructions for medication, and do not use medication on your own.
