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

    Författare :Maria Planck; Bröstcancer-genetik; []
    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. 2. Tumors associated with Hereditary Nonpolyposis Colorectal Cancer: Defective Mismatch Repair and Familial Risk of 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. 3. Someone has to tell them : exploring hereditary cancer risk disclosure in Sweden

    Författare :Carolina Hawranek; Anna Rosén; Senada Hajdarevic; Beatrice S. Melin; Barbro Numan Hellquist; Maria Katapodi; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; hereditary cancer; prevention; family disclosure; family communication; cancer worry; risk information; at-risk relatives; cascade testing; genetic counselling; public opinion; Oncology; onkologi; Genetics; genetik;

    Sammanfattning : Summary in EnglishBackground: An awareness of hereditary susceptibility for breast, ovarian and colorectal cancer in high-risk families enables targeted cancer prevention. A discovered hereditary risk in one family member (proband) may thus be important for several members of that family. LÄS MER

  5. 4. Clinical Aspects of Hereditary Breast Cancer

    Författare :Niklas Loman; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; Cytologi; onkologi; cancerology; oncology; Cytology; Age of onset; Survival analysis; Incidence; Male breast cancer; Steroid receptors; BRCA2; BRCA1; Breast cancer; hereditary;

    Sammanfattning : A positive family history of breast cancer (BC) is one of the strongest predictors of the disease. Two major BC susceptibility genes, BRCA1 and BRCA2 were identified about a decade ago. In this thesis, studies of different biological. clinical and epidemiological aspects of hereditary BC are presented. LÄS MER

  7. 5. Genetic factors in childhood cancer. Associations between tumors in childhood and adulthood, and prevalence of germline TP53 mutations

    Författare :Susanne Magnusson; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood cancer; hereditary factors; breast cancer; survival; hereditary breast and ovarian cancer; hereditary non-polyposis colorectal cancer; familial malignant melanoma; BRCA1; BRCA2; mismatch repair; CDKN2A; familial risk; multiple childhood tumors; Li-Fraumeni syndrome; TP53; adrenocortical carcinoma; choroid plexus tumors; rhabdomyosarcoma;

    Sammanfattning : The etiology of childhood cancer is largely unknown. Approximately 1-10% of all childhood tumors are associated with known cancer predisposition syndromes. However, the contribution may be underestimated due to the failure to detect patients with genetic susceptibility for cancer when relying on known family pattern and anomalies. LÄS MER
