Abstract

Background and Aim: Serum screening systems are beneficial for gastric cancer mass surveys; however, the marker for diffuse type gastric cancer (DGC) is not defined. We attempted to define the high-risk group for DGC by using serum markers of anti-Helicobacter pylori antibody and pepsinogens (PG).

Methods: Forty-two patients in the early stage of DGC and 511 controls were enrolled. Fasting serum samples were collected, and anti-H. pylori antibody and PG were evaluated. The risk for DGC was calculated.

Results: The prevalence of DGC was higher in H. pylori-positive patients (odds ratio [OR] = 4.3 in men, 9.6 in women). DGC prevalence was significantly higher in the PG1+ group in women (OR = 10.7); however, it was lower in the PG3+ group in both men and women. Patients with PG II ≥ 30 revealed a significantly higher risk for DGC. By combining factors, higher OR (OR = 12.5 in men, 42.7 in women) were obtained when we defined the risk group as H. pylori-positive, PG-negative, and having PG II ≥ 30.

Conclusion: The risk group for DGC can be defined by evaluating ordinary serum gastritis markers.
