According to the patient’s condition, surgery can be performed after 3-4 cycles of neoadjuvant chemotherapy, and chemotherapy can be continued after surgery; 3. Advanced gastric cancer: chemotherapy, targeted therapy, biological therapy, Chinese herbal medicine treatment, etc. can be performed. If the patient has distant metastasis or obstruction symptoms, symptomatic treatment can be carried out. If patients are unable to eat, they can be treated with modification surgery.
