Instruments for Evaluating the Nutritional Status of Cancer Patients Undergoing Antineoplastic Treatment: A Scoping Review

Abstract

The use of validated tools to evaluate the nutritional status of the cancer patient provides guaranteed precision and reliability in their nutritional evaluation, ensuring that the information is accurate and reflects the patient’s situation. The aim of this study was to identify the valid and reliable instruments in the evaluation of the nutritional status of cancer patients with a diagnosis of solid tumor undergoing antineoplastic treatment (chemotherapy and/or immunotherapy). A scoping review was conducted to search for original articles published in scientific journals in English, Spanish, or Portuguese in the past five years. In order to identify potentially relevant documents, searches were performed in the following databases: SCOPUS, WOS, CINAHL, MEDLINE, BVS, and PUBMED. DECS-MeSH descriptors and Boolean operators were used. In addition, the Arksey and O’Malley protocol, the Joanne Briggs Institute (JBI) method, and the flow chart of the Preferred Information Elements for Systematic Reviews and Meta-Analyses, known as PRISMA, were followed. The initial search strategy identified a total of 164 references, which were examined successively, leaving a final selection of ten studies. It was found that the most used instrument for nutritional evaluation was the Patient-Generated Subjective Global Assessment (PG-SGA). Other questionnaires also stood out such as the Mini Nutritional Assessment (MNA), the Malnutrition Universal Screening Tool (MUST), the Nutritional Risk Screening (NRS 2002), and the Functional Assessment of Anorexia/Cachexia Therapy (FAACT). The variation in the tools used ranges from subjective assessments to objective measurements, thus underlining the need for a comprehensive and individualized approach.
