Abstract
We aimed to investigate the relationship between preoperative nutritional indicators and sarcopenia in patients diagnosed with stage III colorectal cancer for the first time. To this end, we evaluated the relationships of preoperative anthropometric and nutritional indices obtained by physical measurements and nutritional assessments with skeletal muscle mass index (SMI) measurements obtained using the bioelectrical impedance analysis (BIA) method. The participants were 135 patients (58 women; median age, 69 years). The anthropometric values obtained using an adipometer, and tape measure were evaluated in relation to the Japanese Anthropometric Reference Data (JARD 2001). The anthropometric values were associated with SMI and were highly sensitive to the sarcopenia reference cutoff values indicated by the Asian Working Group for Sarcopenia in 2019. Among the nutritional assessment tools, the Geriatric Nutritional Risk Index was associated with SMI. Thus, preoperative anthropometric values in stage III colorectal cancer patients were associated with measurements obtained using the BIA method and can be considered clinically significant.
