Ulcerated gastric cancer is one of the pathological types of gastric cancer. In the treatment of gastric cancer, the first choice is surgery, which also includes chemotherapy, immunotherapy, biotherapy, Chinese medicine and other comprehensive treatments. Surgery is the only curative treatment and a very important treatment method. At present, the 5-year survival rate of gastric cancer in China may only be 30%. In Japan, the cure rate of gastric cancer can reach 80%-90%, and the early cancer detection rate in Japan is particularly high. Therefore, first of all, it should be emphasized that patients are advised to detect tumors as early as possible and early, which can greatly improve the cure rate of gastric cancer. The occurrence of early cancer is related to patients with family history of gastric cancer, gastritis and gastric ulcer. Gastroscopy should be done early if there are symptoms. As for the detected gastric cancer, we should actively treat it and try to ensure that the surgery is radical and that the D2 lymph nodes are cleared to ensure that the resection is clean and the lymphatic clearance is complete. After surgery, we should actively follow up and do adjuvant chemotherapy to improve the survival rate.
