  2. 11. Genes and brain tumors

    Author : Maral Adel Fahmideh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Although brain tumors are rare and combined with other nervous system tumors account for ~ 2% of all cancers, they are the second most common type of pediatric cancer. The etiology of brain tumors, known as multifactorial traits, is poorly understood. READ MORE

  4. 12. Small Intestinal Neuroendocrine Tumors : Clinical Studies, Novel Serum Biomarkers and Sensitivity to Cytotoxic and Targeted Agents

    Author : Kosmas Daskalakis; Peter Stålberg; Per Hellman; Olov Norlén; Robert Bränström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SI-NET; fibrosis; locoregional surgery; liver transplantation; biomarkers; ex vivo sensitivity.;

    Abstract : Small Intestinal Neuroendocrine Tumors (SI-NETs) are indolent neoplasms with an increasing annual incidence of approximately 1/100 000 people. They are often diagnosed at a late stage, restricting treatment efficacy. READ MORE

  5. 13. Genetic studies of endocrine abdominal tumors

    Author : Ola Hessman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; MEN1; LOH; pancreatic endocrine tumors; midgut carcinoid; Smad4 DPC4; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Pancreatic endocrine tumors (PETs) occur sporadically or in the familial multiple endocrine neoplasia type 1 (MEN1) syndrome, whereas midgut carcinoids are nonfamilial, malignant endocrine tumors of the intestine. For these tumor entities morphological criteria are of limited use for prognostic prediction and selection of treatment. READ MORE

    Author : Elsa Arbajian; Avdelningen för klinisk genetik; []
    Keywords : Soft tissue tumors; Sarcomas; Gene fusions; SNP array; Next generation sequencing; Haploidization; Point mutations;

    Abstract : Soft tissue tumors (STT) constitute a heterogeneous group of tumors that arise in tissues of mesenchymal origin. They are currently classified according to morphology and resemblance to normal tissue into over 100 subtypes. READ MORE

  7. 15. Morphological Features and Mismatch Repair in Colorectal Tumors

    Author : Britta Halvarsson; Tumörmikromiljö; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patologi allmän ; patologisk anatomi; Lynch syndrome; Colorectal tumors; HNPCC; Mismatch repaire; pathological anatomy; General pathology; Genetik; cytogenetik; cytogenetics; Genetics; Medicin människa och djur ; Medicine human and vertebrates ; Immunohistochemistry;

    Abstract : Corlorectal cancer affects 5% of individuals in the Western world and heredity is estimated to cause at least 10% of the tumors. Defective mismatch repair (MMR) is a tumorigenic mechanism through which about 15% of colorectal cancer develops and this feature characterizes tumors associated with Hereditary Nonpolyposis Colorectal Cancer (HNPCC) or Lynch syndrome.
