Aim. We investigated whether there are differences in plasma gastrin, as compared with carcinoembryonic antigen (CEA) and cancer antigen (CA) 19-9 between patients with proximal and distal colorectal cancer. Gastrin concentration has also been analyzed, dependent on the tumor stage, in order to evaluate the possible prognostic role of this measurement. Methods. In 50 patients with colon cancer-fasting gastrin, CA 19-9 and CEA levels were evaluated. Results. Mean plasma-gastrin level in patients with distal tumor yielded 105.31 ± 12.5 µU/L and was significantly higher than in patients with the proximal tumor site (42.2 ± 3.1 µU/L) as well as in controls ( p<0.001). No significant difference was observed between mean plasma gastrin in patients with proximal tumors and the control group. The mean CEA plasma level was significantly higher ( p<0.01) in patients with distal tumors (9.1 ± 1.1 ng/mL) than in those with proximal tumors (1.48 ± 0.1 ng/mL). Similarly, the mean CA 19-9 plasma level was significantly higher ( p<0.01) in patients with distal tumor (19.9 ± 2.1 U/mL) than in those with proximal tumor: 1.8 ± 0.2 U/mL. The mean gastrin plasma, CA 19-9, and CEA level was significantly higher in group of Duke’s stage C and D as compared to A and B. Conclusion. We speculate that observed differences in gastrin concentration in patients with distal and proximal tumors may contribute to the distinct pathogenesis and biological properties of those cancers. The significance of gastrin as a marker for diagnostic or prognostic purposes in colorectal cancer requires further study. [ABSTRACT FROM AUTHOR] |
