  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.

    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. 3. Thyroid cancer : studies on etiology and prognosis

    Författare :Arne Hallquist; Lennart Hardell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Thyroid cancer; prognostic factors; etiology; occupation; medical ionizing radiation; reproductive; and family factors;

    Sammanfattning : Thyroid cancer constitutes about 1% of all malignant tumours and the incidence is increasing in Sweden. It is rare in children before the age of 10. During puberty the female to male ratio increases to be two to three times more common in females. The ratio remains constant until menopause and thereafter declines. LÄS MER

  5. 4. Trends in Prostate Cancer Mortality

    Författare :Andri Wilberg Orrason; Pär Stattin; Alberto Briganti; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; mortality; survival; death certificate; adjudication; lifetime risk; diagnosis; life expectancy; Urologi; Urology; Epidemiologi; Epidemiology; Cancer Epidemiology; Cancerepidemiologi;

    Sammanfattning : In the early 20th century, cancer of the prostate was considered a rare and deadly disease with little to no possibility of cure. Since then, prostate cancer management has improved substantially with earlier detection, hormonal therapy, surgery and radiotherapy of the prostate. LÄS MER

  7. 5. Computational exploration of cancer genomes

    Författare :Joakim Karlsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer genomics; Transcriptomics; Driver genes; Copy number changes; Immunogenomics; Cancer of unknown primary; Uveal melanoma;

    Sammanfattning : Cancer evolves due to changes in DNA that give a cell an advantage at the expense of the remaining organism. These alterations range from individual base substitutions to broad losses or duplications of chromosomal material. LÄS MER
