Abstract：
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.
晚期胃癌一直是临床治疗的难点，也是亟待突破的重点研究方向之一。晚期胃癌患者以非手术治疗为主，但近年来随着治疗手段的进步，部分患者经过有效的术前治疗，肿瘤灶可明显退缩，有望重新获得根治性手术机会。在外科方面，腹腔镜技术目前作为胃癌外科治疗的常规手段之一，在初始可切除胃癌中的治疗效果已经证实，但其在晚期胃癌中的应用仍未有高级别循证医学证据。目前国内外学者广泛参与研究探索，取得了一定的进展。本共识的制订结合当下最新研究进展，采用国际通用的Delphi法经多位专家投票和修改，将晚期胃癌转化治疗后的围手术期分为术前评估、腹腔镜手术的合理实施以及术后评估与治疗三方面，并形成初步共识18条，旨在为广大临床医师提供基本参考与指导。.
