  1. 6. Clinical and Biological Patterns in Soft Tissue Sarcoma

    Författare :Emelie Styring; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiosarcoma; radiation-associated sarcoma; irradiated; RET; KIT; MYC.;

    Sammanfattning : Soft tissue sarcomas (STSs) are rare malignant tumors, of which 3/4 are high-grade and 1/3 metastasize. For optimal management, STSs should be treated at multidisciplinary sarcoma centers. LÄS MER

  3. 7. Growth regulation in sarcomas : studies in vivo and in cell culture

    Författare :Avni Abdiu; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Sarcomas are malignant tumors of mesenchymal origin, and can arise in soft-tissue and in bones. It has been suggested that the abnormal growth regulation in sarcoma cells may be due to an autocrine mechanism, in which the cells are stimulated by an endogenous production of growth factors.

  4. 8. Array based genetic profiling of bone and soft tissue tumors

    Författare :Karolin Hansén Nord; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : In this thesis, genetic alterations in bone and soft tissue tumors have been investigated with the purpose of identifying regions of importance for tumor development, diagnosis and prognosis. This has primarily been performed by array comparative genomic hybridization analysis and gene expression profiling of cytogenetically analyzed tumors. LÄS MER

  5. 9. Tumors associated with Hereditary Nonpolyposis Colorectal Cancer: Defective Mismatch Repair and Familial Risk of Cancer

    Författare :Kajsa Ericson Lindquist; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; cancerology; Cytologi; onkologi; cancer; Multiple Tumors; Hereditary Nonpolyposis Colorectal Cancer; Cytology; Cohort study; Population based; Familial Risk of Cancer; Immunohistochemistry; MSH2; MSH6; MLH1; Microsatellite Instability; Soft Tissue Sarcomas; Cancer of the Upper Urinary Tract; Cancer of the Small Intestine; Colorectal Cancer;

    Sammanfattning : Inactivation of the DNA mismatch repair (MMR) system is a tumorigenic mechanism involved in 15-20% of tumor types such as colorectal and endometrial cancer and is specifically associated with the Hereditary Nonpolyposis Colorectal Cancer (HNPCC) syndrome. These MMR defective tumors are characterized by microsatellite instability (MSI), a phenomenon that reflects alterations in length of repeated sequences, and 90% of MSI tumors show loss of immunohistochemical expression for the MMR protein affected.

  7. 10. Refined diagnosis and prognosis in soft tissue sarcoma - genetic profiles, biomarkers and prognostic models

    Författare :Ana Carneiro; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MFH; microarrays; prognostic factors; metastasis; local recurrence; proliferation; Ki67; Top2a; p21; p27; S-phase fraction; erzin.;

    Sammanfattning : This work aimed at evaluate diagnosis and prognosis in soft tissue sarcoma (STS): In study I, 32K bacterial artificial chromosome (BAC) arrays and gene expression profiling were applied to 18 leiomyosarcomas and 31 undifferentiated pleomorphic sarcomas (UPS), with the aim of identifying molecular subtype signatures. Both the gains/losses profiles and the gene expression signatures revealed striking similarities between the two tumour types. LÄS MER
