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 …

BACKGROUND AND AIMS: Early diagnosis of pancreatic cancer is still an unsolved
problem. Symptoms are often vague or absent in the early stages. Atternpts to detect …

Purpose To investigate the use of pretreatment carbohydrate antigen (CA) 19-9 and
carcinoembryonic antigen (CEA) as prognostic factors to determine survival in pancreatic …

Aims: This study evaluated the prognostic value of the preoperative CEA and CA 19-9 levels
on the survival time and TNM staging in patients with colorectal cancer. Methodology: We …

The diagnostic values of CA 19-9 and CEA were evaluated in 187 cases (including 31
gastric, 41 colorectal, 12 pancreatic, 7 hepatobiliar and 5 hepatocellular carcinomas). These …

BACKGROUND: Serum CA 19-9 is the mainstay marker for the diagnosis of biliopancreatic
malignancies, though a persistent elevation can also be observed in various benign …

Background: The purpose of this study was to assess the predictive effect of preoperative
CEA and CA 19-9 levels on the prognosis of colorectal and gastric cancer patients. Materials …

Purpose Limited data are available regarding the association between circulating serum
carcinoembryonic antigen (CEA) or carbohydrate antigen 19-9 (CA 19-9) concentrations …

BACKGROUND: To clarify the clinical significance of CEA and CA19-9 in patients with
gastric cancer, we evaluated the correlation between tissue expression, the peripheral and …

This study is an evaluation of serum levels in the tumor markers CA 19-9 and CA 72-4 in
gastric cancer patients in preoperative, postoperative and follow-up periods. These tumor …
