title: Oncological outcomes of laparoscopic surgery in elderly patients with colon cancer: a comparison of patients 64 years or younger with those 75 years or older.
abstract: OBJECTIVE
  We compared the results of laparoscopic resection of colon cancer between patients 75 years or older and those 64 years or younger, to confirm whether this procedure is warranted in elderly patients.
  
  
  METHODS
  The study group was comprised of patients with stage I to III colon cancer treated by laparoscopic surgery from 1995 through 2006. Oncologic outcomes were compared between 74 patients 75 years or older (elderly group) and 74 patients 64 years or younger (younger group) who were matched for gender, tumor location and pathological tumor-node-metastasis (TNM) stage.
  
  
  RESULTS
  In patients with stage I or II disease, the disease-free survival rate and overall survival rate were similar in the elderly group (100% and 100%, respectively) and the younger group (95.6% and 95.8%, respectively). In patients with stage III disease, the disease-free survival rate and overall survival rate were also similar in the elderly group (76.7% and 88.5%, respectively) and the younger group (88.5% and 88.5%, respectively).
  
  
  CONCLUSIONS
  Postoperative complications and long-term oncologic outcomes were similar in elderly patients and younger patients with colon cancer who underwent laparoscopic colectomy in our hospital. These results demonstrate that laparoscopic resection of colon cancer is warranted in patients 75 years or older.
