  1. 16. Imaging of soft tissue tumors

    Author : Hildur Einarsdóttir; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Abstract The aim of this project on soft tissue tumors, was to evaluate existing imaging methods and test new Magnetic Resonance Imaging (MRI) sequences for diagnosis and assessment of cytotoxic therapy and to relate the imaging studies to cytology to explore the limitations of each procedure. Patients and method The studies were based on patients with a soft tissue lesion diagnosed and treated at the Orthopedic Tumor Service at the Karolinska Hospital 1990-2003. READ MORE

  2. 17. Accurate description of heterogeneous tumors for biologically optimized radiation therapy

    Author : Johan Nilsson; Bengt Lind; Anders Brahme; Margareta Edgren; Søren Bentzen; Stockholms universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heterogeneous tumors; radiation therapy; biological optimization; tumor hypoxia; effective radiation sensitivity; effective radiation resistance; Radiation biology; Strålningsbiologi;

    Abstract : In this thesis, a model of tissue oxygenation is presented, that takes into account the heterogeneous nature of tumor vasculature. Even though the model is rather simple, the resulting oxygen distributions agree very well with clinically observed oxygen distributions for most tumors and healthy normal tissues. READ MORE

    Abstract : Cancer, historically considered a genetic disease, is currently acknowledged to affect the whole body. Our immune system is one key player that can elicit a response against malignant cells but can also promote tumorigenesis. Tumors avoid immune recognition by creating a suppressive microenvironment and inducing tolerance. READ MORE
