Abstract: The incidence and mortality rates of gastric cancer are in the forefront of malignant tumors in China, and surgical resection is still one of the most important treatment methods. Precision medicine is an important trend in the development of contemporary medicine. However, there is no consensus on the precision surgical diagnosis and treatment of gastric cancer in China. Therefore, Laparoscopic & Endoscopic Surgery Group, Branch of Surgery, Chinese Medical Association combined with The Expert Working Group of Chinese Association of Upper Gastrointes-tinal Surgeons of Chinese Medical Doctor Association and Editorial board of the Chinese Journal of Digestive Surgery organized domestic experts in related fields to formulate the Chinese Expert Consensus on Precision Surgical Diagnosis and Treatment of Gastric Cancer (2024 Edition) (hereinafter referred to as the consensus), based on existing clinical research evidence at home and abroad and combined with the actual situation in China. A number of important issues in the precision surgical treatment strategy of gastric cancer, such as disease assessment, surgical decision‑making, surgical planning, specimen surgical treatment, biobank construction, perioperative adjuvant treatment, postoperative accelerated rehabilitation and humanistic care, were fully discussed. This consensus forms 16 recommendations for the reference of domestic counterparts, aiming to promote the concept of precision surgical diagnosis and treatment of gastric cancer and guide the clinical practice of gastric cancer surgery.
