Abstract: Surgery is the cornerstone of gastric cancer treatment. Surgical treatment of gastric cancer has shown new trends in the context of precision surgery. From standardized D₂ radical surgery to function-saving surgery, minimally invasive surgery and enhanced recovery after surgery, the controlling of surgical trauma and improving life quality of patients are getting more and more attention under the premise of ensuring radical cure. At the same time, the comprehensive treatment including immunotherapy has broadened the boundaries of gastric cancer surgery. Combined with the relevant data at home and abroad, the authors elaborate the new trends in surgical treatment of gastric cancer oriented by stage of gastric cancer, in order to provide new ideas for clinical work.
