中文摘要：

营养不良在恶性肿瘤患者中出现比例较高但往往容易被忽视。对于肝癌患者，严重的营养不良既增加了介入治疗相关不良反应的发生率，又降低了肝癌患者介入治疗效果和生活质量。本文以原发性肝癌、营养不良、介入治疗、营养治疗为主题词在Sinomed和Pubmed中查阅国内外相关文献，对肝癌患者的营养状况评估和介入治疗围手术期患者营养治疗的相关内容进行归纳总结，同时回顾和探讨了肝癌介入治疗围手术期患者营养治疗相关研究与进展，旨在为临床上肝癌介入围手术期患者的营养治疗提供参考。拟行介入治疗的肝癌患者多属肝癌晚期，而且往往合并严重的肝硬化，因此，肝癌介入治疗围手术期患者营养不良发生率较其他非消化系统肿瘤更为常见和严重。BMI、NRS2002和SGA是肝癌常见的营养评估方法，各有其优缺点，需要结合本单位实际情况和患者具体病情合理选择，在肝癌介入治疗围手术期，合理的营养治疗时机、营养治疗途径和营养素构成对于降低介入治疗围手术期患者并发症发生率、维护机体免疫力、提高治疗效果、促进机体康复具有重要意义。

英文摘要：

The prevalence of malnutrition in patients with cancer is relatively high but often overlooked.For liver cancer,severe malnutrition not only increases the incidence of intervention therapy-associated side effects,but also decreases the quality of life and therapeutic effect.Key words like primary carcinoma of the live,malnutrition,intervention therapy and nutrition therapy were used in this study by searching the published literature from Sinomed and Pubmed.The purpose of this study was to provide the reference for clinical application via summarizing and discussing the literature about the nutrition assessment and nutrition therapy for live cancer patients with intervention therapy in perioperative stage.Patients with intervention therapy in most cases are diagnosed with laterstage hepatoma and are often accompanied by severe cirrhosis.Therefore,malnutrition status are more common and more severe inpatients with in tervention therapy in perioperative stage than those with malignant tumors of non-digestive system.BMI,NRS2002and SGA are common nutrition assessments in liver cancer.As each of these assessments presents advantages and disadvantages,realities of situation of hospital and patients’conditions are needed to be considered.Proper nutrition intervention could reduce the complications,maintain patients’immunity,improve the therapeutic effects and promote rehabilitation in perioperative stage.
