ABSTRACT
Introduction; Sarcopenia are frequently observed in cancer patients and was associated with poor prognosis. Objectives; to determine the association of nutritional status, body composition, and clinic parameters with sarcopenia in patients with colorectal cancer (CRC). Methods; We conducted a cross-sectional study of 197 patients with CRC. The sarcopenia elements, including lumbar skeletal muscle index (SMI), handgrip strength, and gait speed were measured. The SMI was assessed by computed tomography at third lumbar vertebra. Phase angle (PA), serum albumin (SAlb), muscle attenuation (MA), and the scored patient-generated subjective global assessment (PG-SGA) were also evaluated. Univariate and multivariate analysis of factors associated with sarcopenia were performed. Results; Sarcopenia was present in 29 of 195 patients (15%) and was significantly correlated with advance age, lower body mass index (BMI), SAlb, PA, MA, higher PG-SGA score, and malnutrition (PG-SGA B). In univariate analysis, age, BMI, SAlb, PA, MA, PG-SGA score, and malnutrition (PG-SGA B) were associated with sarcopenia. Multivariable analysis revealed that BMI, SAlb, PA, MA, and PG-SGA score were independent predictors of sarcopenia. Conclusion; BMI, SAlb, PA, MA, and PG-SGA score were independent predictors of sarcopenia in patients with CRC.
