title: Colorectal cancer treatment in octogenarians: elective or emergency surgery?
abstract: BACKGROUND
  The purpose of this research was to assess the characteristics of octogenarian patients with colorectal cancer and compare specific outcomes due to different types of surgical procedures used to treat the disease.
  
  
  METHODS
  A total of 346 octogenarian patients undergoing surgery for colorectal cancer between April 2000 and April 2010 were retrospectively assessed according to elective (n = 261) or emergent (n = 85) admission group. The two groups were compared for clinical variables, surgical procedures, morbidity and mortality, ICU admission, length of hospital stay and overall survival.
  
  
  RESULTS
  The two groups had similar comorbidities. The emergent group had a more advanced Dukes' stage, higher American Society of Anesthesiologists grading, lower anastomosis rate (40.2 vs 80.1%), higher stoma rate (30.6 vs 9.6%), more complications (71.8 vs 43.3%), nine days longer length of hospital stay and higher (82.4% vs 36.4%) ICU admission rate. Overall mortality was 9.5%, with a higher mortality rate in the emergent group (30.6%) than the elective group (3.1%).
  
  
  CONCLUSIONS
  Octogenarians who undergo elective colorectal cancer surgery have better results than those requiring emergent surgery, but both are quite acceptable and we recommend surgical intervention should not be delayed.
