Abstract: Gastric cancer is one of the high incidence of malignant tumors in China, the incidence of which is in the second among the world and is only inferior to Japan. But the mortality of gastric cancer in China is 2 times of world′s average level, which is often associated with low early diagnostic rate, big regional differentials in the surgical quantity of gastric cancer (especially D₂ radical gastrectomy) and prognosis of patients influenced by surgical quantity. Therefore, a standardized treatment of gastric cancer is the current development trend and hotspot. The correct and programmed staging, evaluation, operation methods, approaches, lymph node dissection and digestive tract reconstruction are selected, thus improving the longterm survival of patients with advanced gastric cancer and reducing mortality in China.
