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

    Author : Kajsa Ericson Lindquist; Bröstcancer-genetik; []
    Keywords : 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;

    Abstract : 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. 7. Colorectal Cancer : Aspects of Heredity, Prognosis and Tumour Markers

    Author : Lana Ghanipour; Helgi Birgisson; Lars Påhlman; Karin Jirström; Tom Öresland; Uppsala universitet; []
    Keywords : colorectal cancer; heredity; Tryptophanyl t-RNA synthetase; microsatellite instability; SP-PLA; prognosis; biomarkers;

    Abstract : Colorectal cancer (CRC) is one of the most common cancer types and leading causes of cancer death worldwide. Since CRC is a heterogenic disease, there is a demand for increased knowledge of the underlying genetic and epigenetic mechanisms. The aim of this thesis was to investigate heredity and potential tumour markers in relation to prognosis. READ MORE

  5. 8. Colorectal cancer : Aspects of staging, treatment, recurrence and survival

    Author : Åsa Collin; Joakim Folkesson; Wilhelm Graf; Malin Enblad; Marie-Louise Lydrup; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer; recurrence; survival; staging; postoperative complications; Kirurgi; Surgery; Oncology; Onkologi;

    Abstract : Colorectal cancer is the third most common malignancy in the world, and major breakthroughs have been made regarding both surgical and oncological treatment. Still, postoperative complications, such as perineal infections after abdominoperineal resection (APR), are a major cause of morbidity, and distant recurrence rate is nearly 20%. READ MORE

  6. 9. Quiescent cancer cells : Three-dimensional cell models for evaluation of new therapeutics

    Author : Frida Ek; Mårten Fryknäs; Malin Jarvius; Rolf Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cancer cell quiescence; dormancy; three-dimensional; multicellular tumor spheroids; model development; cancer pharmacology; mitochondria; OXPHOS; colorectal carcinoma; hepatocellular carcinoma; Medicinsk vetenskap; Medical Science;

    Abstract : Inadequate metabolic conditions in solid tumors lead to the formation of quiescent cancer cells that are suspended in a transient cell cycle arrest. When conditions change, quiescent cancer cells can re-enter the cell cycle and cause recurrence. READ MORE

  7. 10. Genomic Profiling, Mutations and Deranged Signaling in Esophageal Cancer and Hereditary Colorectal Cancer

    Author : Anna Isinger Ekstrand; Institutionen för immunteknologi; []
    Keywords : 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;

    Abstract : 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. READ MORE
