Associations between severe co‐morbidity and muscle measures in advanced non‐small cell lung cancer patients

Background Studies show that low skeletal muscle index (SMI) and low skeletal muscle density (SMD) are negative prognostic factors and associated with more toxicity from systemic therapy in cancer patients. However, muscle depletion can be caused by a range of diseases, and many cancer patients have significant co‐morbidity. The aim of this study was to investigate whether there were associations between co‐morbidity and muscle measures in patients with advanced non‐small cell lung cancer.
