    Sammanfattning : Lynch syndrome (Hereditary Nonpolyposis Colorectal Cancer, HNPCC) is the most common hereditary syndrome predisposing to colorectal cancer, accounting for 1-3% of all colorectal cancer. This multi-organ cancer predisposition syndrome is caused by mutations in the mismatch repair (MMR) genes, especially MLH1 and MSH2, and to lesser extents MSH6 and PMS2, which lead to widespread genetic instability and thus microsatellite instability (MSI).

  2. 2. Hereditary Nonpolyposis Colorectal Cancer - Molecular Genetics and Biology of Associated Tumors

    Detta är en avhandling från Maria Planck, Department of Oncology, Lund University Hospital, SE-221 85 Lund, Sweden

    Författare :Maria Planck; Lund University.; Lunds universitet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endometrial cancer; rectal cancer; colon cancer; mismatch repair protein expression; coding repeats; microsatellite instability; MSH6; MSH2; Hereditary nonpolyposis colorectal cancer; MLH1; small bowel cancer; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : This thesis focuses on one of the most common types of hereditary cancer, hereditary nonpolyposis colorectal cancer (HNPCC). This syndrome is characterized by an autosomal dominant inheritance, an increased risk for several types of cancer (especially cancer of the colorectum, small bowel, endometrium, ovary and urinary tract), early age at diagnosis, and frequent development of multiple primary malignancies.

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

    Detta är en avhandling från Department of Oncology, Clinical Sciences, Lund University

    Författare :Kajsa Ericson Lindquist; Lund University.; Lunds universitet.; [2005]
    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.

  4. 4. Hereditary Ovarian Cancer mutation frequencies and genetic profiles

    Detta är en avhandling från Department of Oncology, Clinical Sciences, Lund University

    Författare :Susanne Malander; Lund University.; Lunds universitet.; [2007]

    Sammanfattning : Ovarian cancer is a leading cause of gynecological cancer death and in Sweden nearly 700 cases are diagnosed annually. Ovarian cancer has one of the highest frequencies of hereditary cancer. LÄS MER

    Detta är en avhandling från Lund University, Faculty of Medicine Doctoral Dissertation

    Författare :Britta Halvarsson; Lund University.; Lunds universitet.; [2007]
    Nyckelord :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;

    Sammanfattning : 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.
