    Abstract : Helicobacter pylori is one of the most common infections in man. The infection is often acquired during childhood and usually results in a chronic life-long inflammation in the gastric mucosa. The aim of our studies was to investigate the association between H. pylori seropositivity and the development of gastric and oesophageal carcinomas. READ MORE

  4. 4. Roles of Helicobacter pylori infection, host genetic variation, and other environmental exposures in gastric carcinogenesis

    Author : Christina Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Despite a general declining secular trend of incidence in most parts of the world, stomach cancer is still a major cause of cancer-related death worldwide due to its poor prognosis. Although Helicobacter pylori (H. pylori) infection is an established risk factor for stomach cancer, the true magnitude of the association is still not determined. READ MORE

    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : The aim of this thesis was to address the hypothesis that estrogen protects women against the development of esophageal and gastric adenocarcinoma (AC). These two cancers show a striking but totally unexplained male predominance in their incidence. READ MORE
