Stomach bug linked to gastric cancer.

A fourth epidemiologic study linking a specific bacterial infection to cancer of the stomach "puts forth beyond a reasonable doubt" the emerging theory that the bug is somehow associated with the often-fatal cancer, says a British researcher.

But it remains unclear whether Helicobacter pylori actually causes gastric cancer, cautions David Forman of the Imperial Cancer Research Fund in Oxford, England. In an editorial accompanying the latest research report - which appears in the Dec. 4 Journal of the National Cancer Institute - Forman writes that proof of a causal tie must await the outcome of future studies testing whether antibiotic treatment can reduce gastric cancer risk.

In the new study, Nicholas J. Talley of the Mayo Clinic in Rochester, Minn., and his colleagues found that patients with gastric cancer were more likely to have antibodies to H. pylori than were healthy volunteers or patients with several other types of cancer.
