1. 16. Cancer of the esophagus and gastric cardia : etiological aspects

   Författare :Jesper Lagergren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Esophageal; gastric cardia; cancer; adenocarcinoma; squamous cell carcinoma; gastroesophageal reflux; body mass; weight; energy intake; physical activity; tobacco; snuff; alcohol; human papillomavirus; sex hormones;

   Sammanfattning : Esophageal cancer is one of the most lethal forms of cancer and the prognosis has not improved substantially during recent decades despite new treatments and diagnostic methods. In view of these discouraging results it is important to identify risk factors that might make primary prevention possible. LÄS MER

3. 17. Aspects on prognosis of cancers of the oesophagus and gastric cardia

   Författare :Martin Sundelöf; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Oesophagus; adenocarcinoma; squamous-cell carcinoma; gastric cardia; prognosis; lifestyle factors; palliation; dysphagia;

   Sammanfattning : Oesophageal cancer is an aggressive form of cancer with a poor prognosis. The two main histological types are squamous-cell carcinoma and adenocarcinoma. In the Western world the incidence rate of adenocarcinoma of the oesophagus, previously rather rare, has shown a dramatic increase in recent decades. LÄS MER

4. 18. Genetic adaptations of Helicobacter pylori during gastric disease progression

   Författare :Helene Kling Bäckhed; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Helicobacter pylori colonizes the stomachs of approximately half of all humans. In the absence of treatment, H. pylori can persist throughout the life of the host. Although most infected individuals are asymptomatic, a significant proportion develops peptic ulcer disease, chronic atrophic gastritis (ChAG) or gastric adenocarcinoma. LÄS MER

5. 19. Interaction between gastric pathogen Helicobacter pylori and host cells

   Författare :Bin Su; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Helicobacter pylori; receptors; Lewis blood group antigen; MCP; integrin and signals;

   Sammanfattning : H. pylori plays a causative role in the pathogenesis of gastritis, gastric atrophy, gastric and duodenal ulcer, and is believed to predispose to gastric adenocarcinoma as well as low-grade B-cell lymphoma. Lewisb (Leb) blood group antigen is a receptor for Leb adhesin-positive H. pylori strains. LÄS MER

7. 20. Trafficking of Human Dendritic Cells and B cells in Helicobacter pylori-induced Gastritis

   Författare :Malin Hansson; Göteborgs universitet; []
   Nyckelord :Helicobacter pylori; migration; homing; dendritic cells; B cells; gastric mucosa;

   Sammanfattning : Infection with the bacterium Helicobacter pylori is widespread throughout the world, and is associated with development of gastric and duodenal ulcer disease as well as gastric adenocarcinoma and mucosa associated lymphoid tissue lymphoma. The infection generally leads to a large infiltration of immune cells, among them dendrite cells (DC) and IgA-secreting cells. LÄS MER
