  1. 1. Prognostic factors in periampullary adenocarcinoma. A retrospective study over an 11 year period

    Författare :Jacob Elebro; Tumörmikromiljö; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periampullary adenocarcinoma; Pancreatic cancer; bile duct cancer; ampullary adenocarcinoma; duodenal adenocarcinoma; Immunohistochemestry; prognosis;

    Sammanfattning : Periampullary adenocarcinoma, including pancreatic cancer, has a poor prognosis that has not improved in the last decades. Therefore, in order to find more effective treatment regimens, it is necessary to gain more insight into the biology and clinical behaviour of these tumours. LÄS MER

  3. 2. Prognostic role of the tumour microenvironment in esophago-gastric, pancreatic and periampullary adenocarcinoma: B cells and beyond

    Författare :Richard Fristedt; Tumörmikromiljö; []
    Nyckelord :Polymeric immunoglobulin receptor; B cells; Plasma cells; Esophageal adenocarcinoma; gastric adenocarcinoma; Pancreatic ductal adenocarcinoma; Periampullary adenocarcinoma; Prognosis and survival; Immune system;

    Sammanfattning : Cancer development depends on cells aquiring a skillset of limitless growth and finally invasive properties to allow for metastasis, as summarised by the six hallmarks of cancer. Recently four more hallmarks have been added: genomic instability, deregulating cellular metabolism, tumour-promoting inflammation and avoiding immune destruction. LÄS MER

  4. 3. Epidemiological Studies of Small Intestinal Tumours

    Författare :Niklas Zar; Per Hellman; Lars Holmberg; Jonas Rastad; Anders Bergenfelz; Uppsala universitet; []
    Nyckelord :Surgery; small intestine; adenocarcinoma; carcinoid; epidemiology; survival; second malignancies; causes of death; Crohn s disease; Kirurgi;

    Sammanfattning : Malignant tumours of the small intestine are rare. Age-standardised incidence in Europe is between 0.5-1.5 per 100 000. LÄS MER

  5. 4. T-cell responses to Helicobacter pylori in humans and a possible role of regulatory T cells

    Författare :Anna Lundgren; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; T cells; regulatory T cells; dendritic cells; T-cell recruitment;

    Sammanfattning : Helicobacter pylori colonize the stomach and areas of gastric metaplasia in the duodenum. The bacteria induce both local and systemic immune responses, but despite this, the infection normally persists for life and causes chronic gastritis in all infected subjects and peptic ulcers or gastric cancer in 10-20% of infected individuals.

  7. 5. Approaches to analyses of cytotoxic cells. And studies of their role in H. pylori infection

    Författare :Josef Azem; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; mucosal immunology; stomach; duodenum; asymptomatic; duodenal ulcer; gastric adenocarcinoma; NK cells; T cells; B cells; dendritic cells; cytotoxic;

    Sammanfattning : Helicobacter pylori infection causes chronic gastritis that may progress to peptic ulcers or gastric adenocarcinoma and thereby cause major world-wide health problems. Previous studies have shown that CD4+ T cells and the production of the cytokine IFN- × are important components of the immune response to H. pylori in humans. LÄS MER
