Serum pepsinogen I level was significantly lower in gastric carcinoma than in controls (55.5 ± 28.1 vs. 76.9 ± 25.1 ng/ml, p < 0.005), but there was no difference in serum gastrin between them (63.2 ± 30.2 vs. 57.4 ± 28.5 pg/ml, p = 0.16). Helicobacter pylori infection caused a significant increase in serum PGI level in advanced, intestinal type, and non-cardia gastric carcinoma. The serum gastrin level was affected by neither Helicobacter pylori infection nor any of the tumor characteristics. It is concluded that pepsinogen I, rather than gastrin, in the serum is greatly influenced by Helicobacter pylori infection and tumor characteristics in gastric carcinoma.en-US[SDGs]SDG3bacterium antibody; gastrin; immunoglobulin g; pepsinogen i; adult; aged; article; controlled study; enzyme blood level; female; gastrin blood level; gram negative infection; helicobacter pylori; human; major clinical study; male; priority journal; stomach carcinoma; Adult; Aged; Aged, 80 and over; Female; Gastrins; Helicobacter Infections; Helicobacter pylori; Human; Male; Middle Age; Pepsinogens; Stomach Neoplasms; Support, Non-U.S. Gov'tjournal article81196482-s2.0-0027724866
