ObjectivesThe aim of this study was to determine the feasibility of substituting handgrip strength (HGS) for muscle mass as a constituent in the Global Leadership Initiative on Malnutrition (GLIM) to diagnose malnourished patients with gastrointestinal (GI) cancer.MethodsThe study included 2209 patients diagnosed with GI cancer from two centers. All patients were evaluated for nutritional risk using Nutritional Risk Screening 2002 within 24 h of admission. The GLIM consensus was then used to diagnose malnourished patients. The evaluation of muscle mass as one of the constituents contained in the GLIM consensus was measured by computed tomography presented as skeletal muscle mass index (SMI) and HGS, respectively. Consistency test was carried out to evaluate the diagnostic value of SMI and HGS.ResultsThere were 1042 (47.2%) cases of gastric cancer and 1167 (52.8%) cases of colorectal cancer. Among these cases were 768 patients (34.8%) at nutritional risk. Furthermore, 603 (27.3%) and 593 patients (26.8%) were diagnosed with malnutrition in the GLIM (SMI) group and the GLIM (HGS) group, respectively, and 544 (24.6%) patients in the two groups overlapped. The consistency test results showed that the κ value in the GLIM (HGS) group compared with the GLIM (SMI) group was 0.881 (P < 0.001) in patients with gastric cancer and 0.872 (P < 0.001) in those with colorectal cancer.ConclusionHGS can be a substitute for muscle mass as a constituent in the diagnostic criteria of GLIM in patients with GI cancer.Copyright © 2020 Elsevier Inc.
