The purpose of this systematic review was to identify validated nutritional screening tools for cancer patients. The research was conducted in the electronic databases Pubmed, Cochrane Library, Scopus, and , using the descriptors "Nutrition Assessment", "Neoplasms", and "Validation studies". Initially, we identified 168 articles. After assessing eligibility, we included 21 studies. In selected studies, 14 nutritional screening tools were validation objects. The Patient-Generated Subjective Global Assessment (PG-SGA) showed better sensitivity, specificity and positive and negative predictive values (98, 82, 95, and 93%, respectively), as well as predictive of overall survival in cancer patients. In many countries, in addition to PG-SGA, the Nutrition Risk Screen (NRS-2002) is recommended for these patients. We did not identify, however, manuscripts that proposed validation. Validation studies of nutritional screening tools should be performed on patients with cancer, using representative samples of these individuals for better reliability of their results.
本系统评价的目的是确定经过验证的癌症患者营养筛查工具。研究在电子数据库 PubMed、Cochrane Library、Scopus 和 中进行，使用的检索词为“Nutrition Assessment”、“Neoplasms”和“Validation studies”。最初，我们确定了 168 篇文章。经过评估资格，我们纳入了 21 项研究。在选定的研究中，14 种营养筛查工具作为验证对象。患者主观整体评估（PG-SGA）显示出更好的敏感性、特异性和阳性及阴性预测值（分别为 98%、82%、95%和 93%），并且可预测癌症患者的总生存率。在许多国家，除了 PG-SGA 外，还推荐对这些患者使用营养风险筛查（NRS-2002）。然而，我们没有发现提出验证的文献。应在癌症患者中进行营养筛查工具的验证研究，使用这些患者的代表性样本，以提高其结果的可靠性。
