  • Title: The relation of serum pepsinogen to gastric cancer and its precursors in Hawaii Japanese men: a progress report.
    Author: Stemmermann GN, Heilbrun LK, Nomura A, Samloff IM.
    Journal: Prog Clin Biol Res; 1985; 173():213-20. PubMed ID: 3983194.
    Abstract:
    Prospective epidemiologic studies among Hawaii Japanese indicate that serum PG I levels below 20 micrograms/1 are highly specific for the presence of intestinal metaplasia and the intestinal type of gastric cancer; but this test shows a low level of sensitivity. Substitution of the PG I/PG II ratio for the PG I level results in a modest improvement in the level of sensitivity at the expense of some loss in specificity. Antral gastritis and intestinal metaplasia are gastric cancer precursors in this population. Abnormally low values of serum PG I or the PG I/PG II ratio predict high stage tumors in the majority of cases. It therefore does not seem likely that estimates of serum pepsinogen are likely to increase the frequency of the diagnosis of early intestinal type carcinoma of the antral portion of the stomach in this population.
