  2. 1. Tumor Stroma in Anaplastic Thyroid Carcinoma : Interstitial Collagen and Tumor Interstitial Fluid Pressure

    Author : Ellen Lammerts; Lucio Nitsch; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Collagen I synthesis; Fibrosis; Tumor - stroma interactions; PDGF; TGF-β; Inhibitor; Cell cycle; Tumor growth; Hyaluronan; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Abstract : Anaplastic thyroid carcinoma (ATC) is an aggressive malignancy in man with stromal fibrosis as one of the main features. Carcinoma cells synthesized no or little collagen I protein. READ MORE

  4. 2. Stromal and tumor cell responses to hypoxia and treatment within the glioma microenvironment

    Author : Vasiliki Pantazopoulou; Avdelningen för translationell cancerforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; glioblastoma; tumor microenvironment; reactive astrocytes; hypoxia; CD44; p75NTR;

    Abstract : Glioblastoma is the most aggressive primary brain tumor in adults. Despite treatment, tumors invariably recur, and the recurring tumor is resistant to therapies. New approaches are needed for the successful treatment of glioblastoma patients.Tumors are not simply a compilation of molecularly and phenotypically identical neoplastic cells. READ MORE

  5. 3. Gastrointestinal stromal tumors. Pathogenetic mechanisms, phenotypic characterization and prognosis

    Author : Johanna Andersson; Göteborgs universitet; []
    Keywords : Gastrointestinal stromal tumor GIST ; neurofibromatosis type I NF1 ; mutation; prognosis; denaturating high performance liquid chromatography dHPLC ; sequencing; KIT; PDGFRA; NF1;

    Abstract : Gastrointestinal stromal tumor (GIST), the most common non-epithelial neoplasm of the gastrointestinal tract, has historically been problematic both conceptually and clinically. Recently, GIST has been shown to share phenotypic features with the interstitial cells of Cajal (ICC), including the almost uniform expression of the tyrosine kinase receptor KIT. READ MORE

  6. 4. Targeting stromal components in the tumor microenvironment for cancer therapy

    Author : Jieyu Wu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In the tumor microenvironment (TME), different cell components crosstalk with each other through various growth factors, cytokines, chemokines, and enzymes. They offered crucial survival signals for tumor cell proliferation and metastasis. READ MORE

  7. 5. Pancreatic Endocrine Tumors and GIST - Clinical Markers, Epidemiology and Treatment

    Author : Sara Ekeblad; Britt Skogseid; Peter Stålberg; Barbro Eriksson; Rajesh Thakker; Uppsala universitet; []
    Keywords : Medicine; Pancreatic endocrine tumor; Gastrointestinal stromal tumor; Neuroendocrine; Multiple endocrine neoplasia type 1; Prognostic factors; Temozolomide; TNM staging; O6-methylguanine DNA methyltransferase; Growth hormone secretagogue receptor; Ghrelin; Medicin;

    Abstract : Pancreatic endocrine tumors and gastrointestinal stromal tumors are rare. Evidence regarding prognostic factors, and in the former also treatment, is scarce. We evaluated the survival and prognostic factors in a consecutive series of 324 patients with pancreatic endocrine tumors treated at a single institution. READ MORE
