进展期胃癌患者的围手术期治疗是提高胃癌整体疗效、改善预后的重要环节。可切除胃癌围手术期治疗的主要模式为Dn 1/Dn 2手术+围手术期化疗、Dn 0/Dn 1手术+辅助放化疗和Dn 2手术+辅助化疗。多年来，业内围绕如何进一步优化胃癌围手术期治疗模式开展了大量临床研究，包括术后放化疗模式的优化、围手术期化疗模式的优化；并探索了术前放化疗、靶向治疗和免疫治疗在进展期胃癌围手术期中的治疗。虽然经历了近20年的发展与探索，进展期胃癌的围手术期治疗模式目前已经日趋成熟，但仍遗留了一些核心问题急需解决，包括进展期胃癌围手术期治疗获益人群的选择尚未完全明确，疗效评价体系存在局限性，新辅助治疗前的腹腔镜探查尚不够重视，食管胃结合部肿瘤诊治模式的探索和研究尚显不足等。我们应该在临床实践中充分结合目前临床研究数据，通过多学科诊疗模式，在对患者特征进行多方位的分析基础上，遵循规范化诊治的原则，拟定最合理的治疗策略，最终使患者获益。n “,”Perioperative treatment is critical to improve the outcomes of patients with advanced gastric cancer. There are three therapeutic modes of perioperative treatment for resectable gastric cancer: neoadjuvant chemotherapy+ D1/D2 surgery+ adjuvant chemotherapy, D0/D1 surgery+ adjuvant radiochemotherapy, and D2 surgery+ adjuvant chemotherapy. Over the decades, a large number of clinical studies had been conducted to optimize the perioperative treatment mode of gastric cancer, including the postoperative radiotherapy and chemotherapy, and perioperative chemotherapy, and to explore the feasibility of preoperative radiochemotherapy, targeted therapy, and immunotherapy in advanced gastric cancer. After nearly 20 years of development and exploration, although the perioperative treatment mode for advanced gastric cancer has become standardized, there are still some core issues that need to be solved urgently, including the selection of population for perioperative treatment, the limitation of efficaly evaluation criteria, insufficient emphasis on laparoscopic exploration before neoadjuvant treatment, and lack of exploration in esophagogastric junction cancer. We should fully integrate the current clinical research data into clinical practice, adopt a multidisciplinary diagnosis and treatment mode, and follow the principles of standardized diagnosis and treatment based on a multi-dimensional analysis of patient characteristics, and formulate the most reasonable treatment strategy to ultimately benefit patients.
