title: [Survey of cachexia in digestive system cancer patients and its impact on clinical outcomes].
abstract: OBJECTIVE
  To investigate cachexia in hospitalized patients with digestive system cancer and evaluate its impact on clinical outcomes.
  
  
  METHODS
  By analyzing the clinical data of 5118 hospitalized patients with digestive system cancer in Zhongshan Hospital of Fudan University from January 2012 to December 2013, cachexia was investigated and clinical outcomes between cachexia patients and non-cachexia patients was compared.
  
  
  RESULTS
  The total cachexia rate of hospitalized patients with digestive system cancer was 15.7%(803/5118). The highest rate of cachexia was 34.0%(89/262) in patients with pancreatic cancer followed by gastric cancer 22.4%(261/1164), colon cancer 21.7%(146/672), and rectal cancer 20.1%(117/581). In cachexia group and non-cachexia group, the overall completion rate of radical resection was 67.1%(539/803) and 74.5%(3214/4315) respectively(P<0.05). Compared to the non-cachexia group, the cachexia group was associated with longer postoperative hospital stay [(11.5±6.2) d vs. (9.4±4.9) d, P<0.05], slower postoperative recovery of bowel function [(3.4±0.9) d vs. (3.2±0.8) d, P<0.05], longer postoperative time to intake of semifluid [(4.4±1.5) d vs. (3.9±1.1) d, P<0.05], and more postoperative complications within 28 days after radical surgery [8.9%(48/539) vs. 5.8%(186/3214), P<0.05]. After radical surgery, the ICU admission rate of the cachexia group [24.3%(131/539)] was higher than that of the non-cachexia group [20.1%(646/3214)] with significant difference(P<0.05). Compared to non-cachexia group, the reoperation rate [3.2%(17/539) vs. 1.5%(48/3214), P<0.05], ventilator support rate [8.0%(43/539)vs. 5.7%(184/3214), P<0.05] and mortality [2.4%(13/539) vs. 1.1%(35/3214), P<0.05] in the cachexia group were all significantly higher(all P<0.05).
  
  
  CONCLUSIONS
  Cachexia is commen in patients with digestive system cancer. Cachexia has significant adverse effects on clinical outcomes in hospitalized patients with digestive system cancer.
