Tumor-related factors (tumor location, carcinoembryonic antigen [CEA]), pathologic factors (stage, lymph node status, lymph-vascular invasion), patient-related factors (American Society of Anesthesiologist [ASA] physical status), and nutritional factor (CONUT score) did not differ significantly according to pre-sarcopenia status (Table 1). This evidence concerns the gene CEACAM5 and neoplasm.
