[Detection of Helicobacter pylori in stomach cancer].

Helicobacter pylori (HP) infection was detected in different segments of the gastric mucosa in 13 patients with stomach tumors. Twenty five patients suffering from stomach ulcers were used as controls. HP infection was diagnosed by means of urease and microbiological testing. HP was identified in all cases of stomach cancer, the rates of dissemination in the mucosa in such patients being higher than in those with stomach ulcers.
