RESUMEN
Standardized diagnosis and treatment of malignant tumors is very important for the prognosis of patients. Due to the huge land area and large population, there are regional differences in standardized diagnosis and treatment of malignant tumors in China. Therefore, surgical experts from China and Japan planned, and editorial board of Chinese Journal of Digestive Surgery held the meeting of 4K standard Sino-Japanese gastrointestinal minimally invasive surgery with the purpose to build an academic communication platform for Chinese and Japanese experts of young and middle-aged who engaged in gastrointestinal minimally invasive surgery, to promote the standardization and refinements, and to lead the development of gastrointestinal minimally invasive surgery in China. Since 2018, the author had participated in 5 times of the meeting of 4K standard Sino-Japanese gastrointestinal minimally invasive surgery to interpret the operation technology of laparos-copic gastric cancer surgery and introduce the recognition standard of laparoscopic technology of the Japan Society for Endoscopic Surgery. This would promote the standardization of laparoscopic gastric cancer surgery technology, improve the teaching effect of young and middle aged doctors, and promote the overall deve-lopment of the level of diagnosis and treatment of gastric cancer.

RESUMEN
The treatment of gastric cancer in Japan is formulated according to the classification and the guidelines describe treatment methods.The last revision of Japanese Gastric Cancer Treatment Guidelines adopted the 7th edition of TNM stage classification,which was a major revision since the publication.This revision of the 15th edition of the classification is a combination of the revision of the 8th edition TNM classification and clinical experience.A stage revision and a clinical stage were newly established.In addition,the guidelines for the treatment of gastric cancer have also been revised at the same time,becoming the 5th edition,consistent with the new classification and its stage classification.Clinical trials on nationwide wellcontrolled gastric cancer surgery have come to be carried out in recent years,and these results are the source of evidence for the world.These results are also included in this revised guideline.Expansion surgery such as left thoracotomy and laparotomy for esophageal infiltrating gastric cancer and prophylactic para-aortic lymph node dissection is denied from these clinical trials.In total gastrectomy for advanced gastric cancer that does not invade the greater curvature,splenectomy is unnecesary.Since gastrectomy followed by chemotherapy did not show any survival benefit compared with chemotherapy alone in advanced gastric cancer with a single non-curable factor and without bleeding or stenosis,gastrectomy cannot be justified for treatment of patients with these tumors.Laparoscopic pyloric lateral gastrectomy for early gastric cancer is fairly widespread and it is not an exaggeration to say that it is a standardized treatment.However,totally laparoscopic gastrectomy for advanced gastric cancer is currently awaiting results of randomized controlled trials.
