Aim: Previous studies have examined levels of CEA and CA 19-9 in esophageal cancer patients, but have not determined a significant relationship between CEA and CA 19-9 levels and liver metastasis and pancreatic invasion in patients with esophageal cancer. In this study, we compared the serum levels of CEA and CA 19-9 in patients with esophageal cancer with and without liver and pancreatic metastasis.
