There were no significant differences between normal BMD and osteopenia patients regarding the incidence of myosteatosis (p = 0.3829), sarcopenia (p = 0.6982), American Society of Anesthesiologists Score (p = 0.8000), neutrophil–lymphocyte ratio (p = 0.7498), prognostic nutrition index (p = 0.4096), intraoperative blood loss (p = 0.1601), carcinoembryonic antigen level (p = 0.2899), carbohydrate antigen 19-9 level (p = 0.1880), rate of R0 resection (p = 0.2464), stage (p = 0.6956), T stage (p = 0.8285), and nodal status (p = 0.3980). This evidence concerns the gene CEACAM5 and sarcopenia.
