[Consensus on the rational implementation of laparoscopic surgery after conversion therapy in far-advanced gastric cancer (first edition)].

Far-advanced gastric cancer has always been a challenging problem in clinical treatment and a key direction for breakthrough research. Non-surgical treatments are primarily managed in patients with far-advanced gastric cancer. However, with the advancement of therapeutic methods in recent years, tumor foci can be significantly regressed after effective preoperative treatment, in prospect ofregaining the opportunity of radical gastrectomy. In the surgical field, laparoscopic surgery, as one of the routine methods for gastric cancer, has proven effective in the treatment of initially resectable gastric cancer. However, its application in far-advanced gastric cancer still lacks high-level medical evidence. Nevertheless, global clinicians have widely participated in research exploration, achieving certain progress. This consensus, formulated based on the latest research developments and adopting through the international Delphi method with multiple expert votes and amendments, divides the perioperative period after conversion therapy for far-advanced gastric cancer into three parts, i.e., preoperative assessment, rational implementation of laparoscopic surgery, and postoperative assessment and treatment. It forms a preliminary consensus of 18 items, aiming to provide a basic reference and guidance for clinicians.
