title: Increase in both CEA and CA19-9 in sera is an independent prognostic indicator in colorectal carcinoma.
abstract: OBJECTIVE
  Carcinoembryonic antigen (CEA) and carbohydrate antigen (CA19-9) are well known to be the most common tumor markers of colorectal carcinomas. However, the significance of increase in these markers to predict the prognosis of the patients remains a problem for debate.
  
  
  METHODS
  One hundred three patients with colorectal carcinoma, who had been treated by resection and reconstruction of digestive tracts were studied. Correlation of preoperative serum value of CEA and CA19-9 with clinicopathologic features including prognosis of the patients was investigated.
  
  
  RESULTS
  Preoperative elevation of both of the two markers proved to be an independent prognostic indicator, however, an elevation of only one of the two markers did not obtain a prognostic significance.
  
  
  CONCLUSIONS
  Combined data of preoperative increase in CEA and CA19-9 in sera can provide a powerful and useful information to predict prognosis of patients with colorectal carcinoma.
