    Nyckelord :X-ray Computed Tomography; Computed Tomographic Colonography; Computer-Assisted Image Processing; Three-Dimensional Imaging; Colonoscopy; Colon; Rectum; Colorectal Neoplasms; Computer-Assisted Diagnosis; Ionizing Radiation;

    Sammanfattning : Background: Computed tomographic colonography (CTC) is a minimally invasive imaging method for the detection of colorectal neoplasms. Uncertainty about its diagnostic performance, optimal visualization method, long learning curve and radiation exposure are among problems with CTC, affecting its implementation in routine health care.

  5. 4. Cancer of the Colon and Rectum : Prognostic Factors and Early Detection

    Författare :Ulrik Wallin; Helgi Birgisson; Niels Qvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer screening predictive markers prognostic markers;

    Sammanfattning : Colorectal cancer (CRC) is one of the most common causes of death from malignant disease. Nevertheless, no ideal screening method exists and there is a lack of prognostic and predictive factors to support clinical decisions and to aid the development of a more individualized treatment for patients with CRC.

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

    Författare :Helgi Birgisson; Lars Påhlman; Bengt Glimelius; Ulf Gunnarsson; Ragnar Hultborn; Uppsala universitet; []
    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
