Abstract

Background: Gastric carcinoma is the second most common cause of cancer-related death in Iran. It is well-known that atrophic gastritis is a major risk factor for gastric cancer, which leads to variations in the serum levels of gastrin 17 (G-17), pepsinogen I (P-I), and pepsinogen II (P-II). The aim of this study was to investigate the diagnostic accuracy of these serum biomarkers in the early detection of atrophic gastritis. Materials and Methods: A total of 132 dyspeptic patients underwent upper endoscopy and biopsies were taken. The biopsy specimens were evaluated as the gold standard according to operative link for gastritis assessment staging system. Serum levels of G-17, P-I, and P-II were investigated using enzyme-linked immunosorbent assay. Receiver operating characteristic (ROC) analysis was used to calculate the diagnostic indices and optimal cut-off values using Statistical Package for the Social Sciences SPSS statistical software. Results: A total of 67 men and 65 women were analyzed, among which 48 (36.4) had atrophic gastritis. The mean age was 45.8 (+/- 15.8) years. ROC curve analysis demonstrated that the biomarkers (including pepsinogen I/II P-I/II ratio), except for P-I, are diagnostically significant in detecting gastric atrophy. The area under the curve (95% confidence interval CI) for G-17, P-I, P-II, and P-I/II ratio were 0.65 (0.55-0.76), 0.42 (0.32-0.53), 0.62 (0.52-0.72), and 0.61 (0.50-0.72), respectively. However, the diagnostic indices were low (sensitivity <50%, specificity <90%). The prevalence of Helicobacter pylori infection was significantly higher in patients with atrophy against those without atrophy (75.0% vs. 57.4%, P value <0.0001). Conclusion: In the studied population, the serum biomarkers of atrophic gastritis are not useful screening tests due to their low sensitivity.
