title: Metachronous colorectal cancer.
abstract: OBJECTIVE
  In this study, we present our patients with metachronous colorectal cancer.
  
  
  METHODS
  In the period between 1990 and 2009, 670 patients with colorectal cancer were treated.
  
  
  RESULTS
  Metachronous cancer was developed in 4 (0.6%) patients. The time interval between index and metachronous cancer was 28 months to 22 years (mean 146 months).
  
  
  CONCLUSIONS
  Metachronous colorectal cancer is a potential risk that proves the necessity of postoperative colonoscopic control of all patients with colorectal cancer.
