Patients with benign mesenchymal tumors can survive for a long time after surgical removal without affecting survival time. However, malignant mesenchymal tumors have an impact on survival, and it is necessary to do biotargeted therapy or chemotherapy after surgery, and to have regular review to observe the situation of the lesions. Mesenchymal tumors are generally between benign and malignant, smaller mesenchymal tumors with a diameter of <2cm are generally benign. Patients can do pathological examination of mesenchymal tumors to observe whether there are heterogeneous cells to determine benign or malignant, and can also do systemic examination to determine whether there are metastatic foci. If it is clear that the mesenchymal tumor is benign, it can be removed laparoscopically, endoscopically or surgically. After resection, if the mesenchymal tumor is completely removed, it usually will not recur and can be cured without the need for the next step of chemotherapy or biotargeted therapy, which has no effect on life expectancy. After surgical resection, it is necessary to have a regular review to observe whether there is a possibility of recurrence, and if necessary, to do another pathological examination, if it is a gastric mesenchymal tumor, once the operation returns to normal, it can be discharged from the hospital.
