   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

3. 2. Morphological Features and Mismatch Repair in Colorectal Tumors

   Författare :Britta Halvarsson; Tumörmikromiljö; []
   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.

4. 3. Genomic Profiling, Mutations and Deranged Signaling in Esophageal Cancer and Hereditary Colorectal Cancer

   Författare :Anna Isinger Ekstrand; Institutionen för immunteknologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal cancer; hereditary cancer; HNPCC; copy number analysis; CGH; gene expression; Wnt; PIK3CA; CHEK2; gastric cancer; colorectal cancer;

   Sammanfattning : Esophageal cancer and colorectal cancer represents two major types of gastrointestinal tumors. Though refined surgery and introduction of novel chemotherapeutics have improved outcome, more than 2500 Swedes die from these diseases every year. Novel markers for early diagnosis, prognosis and treatment prediction are therefore needed. LÄS MER

5. 4. Genetic and epidemiological studies of hereditary colorectal cancer

   Författare :Kristina Cederquist; Henrik Grönberg; Irina Golovleva; Gösta Holmgren; Mef Nilbert; Umeå universitet; []

   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).

7. 5. Molecular genetic studies on genes involved in hereditary nonpolyposis colorectal cancer (HNPCC)

   Författare :Tao Liu; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :colorectal cancer; endometrial cancer; HNPCC; mismatch repair genes; bhMSH2; hMLH1; hPMS1; hPMS2; hMSH6; mutation screening; MSI; LOH.;

   Sammanfattning : Colorectal cancer (CRC) is a major public health problem in Western countries, and it is the third leading cause of death from cancer in both males and females. Inherited predisposition can be divided into two subgroups based on the absence or the presence of multiple benign colorectal polyps. LÄS MER
