Abstract

 
Background: Gastric cancer is the second leading cause of cancer-related mortality and the fourth most common cancer globally. Tumor markers are needed for appropriate management and monitoring of treatment to improve quality of life. Recently, carcinoembryonic antigen (CEA) has been widely used as a tumor marker in the diagnosis and follow-up of some malignancies. The aim of this study was to evaluate the significance of CEA detection in the course of disease in gastric cancer patients at different stages. Methods: Seventy six cases of gastric adenocarcinoma from the Rasht Razi Hospital were studied between January 2016 and December 2016, along with a control group of 152 people. Serum CEA was measured by ELISA reader. Statistical analysis was performed using SPSS 14.0 for Windows (SPSS Inc., Chicago, USA). The two groups were also compared by cross-table analysis using Pearson’s chi-square test, with P-values Results: CEA was positive in 61.8 % of patients versus 2.6% of the control group (P = 0.0001). Some 21% of patients at stages I and II (initial disease) and 40.8% at stages III and IV (advanced disease) demonstrated positive CEA. which was significantly correlated with higher N stage and poor differentiation. Conclusions: Our study showed that a high preoperative CEA level was not prevalent in early stage gastric cancer patients. We recommend to design other prospective studies and meta-analyses for elucidation of claims for diagnostic efficacy.
