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

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.

3. Body Protein and its Change in Patients During Anti-Tumor Treatment
Sammanfattning : The purpose of this study was to investigate how total body protein and its fraction of body weight (body protein fraction) change in cancer patients during different anti-tumor treatments, and to see if these changes have any clinical significance in the form of prognostic value or correlation with disease course and tumor response. In 84 patients, 28 with lung cancer, 24 with gastrointestinal tumors, 30 with breast cancer, 1 with non-Hodgkin lymphoma and 1 with kidney cancer, the total amount of body nitrogen was measured using an in vivo prompt gamma neutron activation technique.

4. Mismatch Repair Deficient Cancer Diagnostic Aspects in Colorectal Cancer and the Role of Urological Cancer in Lynch Syndrome
Sammanfattning : Mismatch repair (MMR) deficiency is carcinogenic and can either have somatic/sporadic causes (i.e. epigenetic silencing or somatic inactivation) or hereditary causes (Lynch syndrome due to a germline mutation in one of the MMR genes ¬- MLH1, MSH2, MSH6, PMS2). LÄS MER
5. Circulating markers of risk and etiology in colorectal cancer
Sammanfattning : Background: Colorectal cancer is the third most commonly diagnosed cancer in men and women. Worldwide around 2 million individuals are diagnosed each year – a number expected to increase as colorectal cancer risk factors become more prevalent. LÄS MER
