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

    Detta är en avhandling från Maria Planck, Department of Oncology, Lund University Hospital, SE-221 85 Lund, Sweden

    Författare :Maria Planck; [2002]
    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.

  2. 2. Chemoradiation in Gastrointestinal Cancer

    Detta är en avhandling från Lund University: Faculty of Medicine

    Författare :Adalsteinn Gunnlaugsson; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biliary tract cancer; capecitabine; cholangiocarcinoma; chemoradiation; colon cancer; enteritis 5-fluorouracil; gallbladder cancer; oxaliplatin; pancreatic cancer; rectal cancer.;

    Sammanfattning : Locally advanced inextirpable gastrointestinal cancer has poor prognosis and is associated with high morbidity. One treatment option is to use radiotherapy, often combined with chemotherapy (chemoradiation), either as preoperative treatment to facilitate surgery or in the palliative setting to relieve symptoms.

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

    Detta är en avhandling från Department of Oncology, Clinical Sciences, Lund University

    Författare :Kajsa Ericson Lindquist; [2005]
    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. 4. Comparative Treatment Planning in Radiotherapy and Clinical Impact of Proton Relative Biological Effectiveness

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jonas Johansson; Bengt Glimelius; Anders Montelius; Tony Lomax; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; Comparative studies; Breast cancer; hypopharyngeal cancer; rectal cancer; Proton RBE; Onkologi; MEDICINE Surgery Oncology; MEDICIN Kirurgi Onkologi;

    Sammanfattning : The development of new irradiation techniques is presently a very active field of research with increased availability of more sophisticated modalities such as intensity modulated photons (IMRT), protons and light ions. The primary aim of this work is to evaluate if the dose-distributions using IMRT and protons contribute to clinical advantages. LÄS MER

  5. 5. Cancer of the Colon and Rectum Population Based Survival Analysis and Study on Adverse Effects of Radiation Therapy for Rectal Cancer

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Helgi Birgisson; Lars Påhlman; Bengt Glimelius; Ulf Gunnarsson; Ragnar Hultborn; [2006]
    Nyckelord :Surgery; cancer; colon; rectal; colorectal; survival; radiation therapy; second cancer; adverse effects; Kirurgi;

    Sammanfattning : The Swedish Cancer Register was used to determine the relative survival rate in colon and rectal cancer and to estimate the occurrence of second cancers related to radiation therapy for rectal cancer. The Swedish Hospital Discharge Register and hospital records were used to estimate the rate of late adverse effects due to radiation therapy for rectal cancer. LÄS MER
