AbstractThe aim of this scoping review was to characterize the diagnostic criteria, their cutoff values, and the prevalence of cachexia in Asians. We systematically reviewed studies involving Asian adult patients with cachexia due to cancer and chronic diseases other than cancer, such as heart and renal failure. Sources in English and Japanese published between December 2008 and April 2022, including observational, longitudinal, cross-sectional, and clinical trials, were examined. We searched six databases. Altogether, 4131 studies were screened, and 107 eligible articles were identified, of which 11 and 96 were conducted on non-cancer and cancer patients, respectively. The most common clinical indicators used for diagnosis were weight loss, body mass index (BMI), and muscle mass. The most frequently employed diagnostic criteria for cachexia in non-cancer patients were the modified/excerpt Evans criteria. Contrarily, the original Fearon's criteria were often used in patients with cancer. Additionally, cutoff values for BMI and muscle mass affected by racial anthropometric differences were investigated. The mean or median value of BMI ranges were 18.3 to 25.2 and 17.5 to 25 kg/m2 for non-cancer and cancer patients, respectively. The prevalence rates of cachexia were 3.4% to 66.2% and 6.2% to 93% in non-cancer and cancer patients, respectively. Several diagnostic criteria, such as BMI and muscle mass, have been used, which are affected by racial differences in body size. However, few studies have used cutoff values for Asians.Copyright © 2023 Elsevier Inc. All rights reserved.
