【摘要】 胃癌是世界上常见的肿瘤之一，也是癌症死亡的主要病因，随着诊断和治疗水平的提高，胃癌患者的5年生存率有了很大的提升，但是胃癌患者的高营养不良率仍然对患者的总体生存和生活质量有重大影响，营养不良被认为是癌症患者的独立预后因素，早期发现胃癌患者的营养不良，更加合理的围术期营养支持对胃癌患者的生存和预后起着重要作用，本文结合国内外现有研究，对胃癌围术期患者的营养风险筛查和评估，围术期营养支持和免疫营养的研究进展进行综述，以期为胃癌围术期患者提供更加完善的营养管理策略。更多还原

【Abstract】 Gastric cancer is one of the common tumors in the world and a major cause of cancer death.Although the 5-year survival rate of gastric cancer patients has increased greatly with the improvement levels of diagnosis and treatment, the high malnutrition rate of gastric cancer patients still has a significant impact on their overall survival and quality of life.Malnutrition is considered an independent prognostic factor for cancer patients, early detection of malnutrition in gastric cancer patients and more reasonable perioperative nutritional support play an important role in the survival and prognosis of gastric cancer patients.This article combines existing research at domestic and abroad to review the nutritional risk screening and assessment of gastric cancer patients during perioperative period, as well as the research progress of perioperative nutritional support and immunonutrition, in order to provide more comprehensive nutritional management strategies for patients with gastric cancer during the perioperative period.更多还原
