  1. 1. Experimental treatment of patients with disseminated malignant melanoma

    Författare :Aglaia Schiza; Gustav Ullenhag; Angelica Loskog; Sara Mangsbo; Thomas Tötterman; Ola Winqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malignant melanoma; AdCD40L; immunotherapy; proteomics; DW-MRI; FDG-PET CT; prediction; early response; BRAF-inhibitor; vemurafenib; Oncology; Onkologi;

    Sammanfattning : Malignant melanoma (MM) is the deadliest skin cancer with an ever-increasing incidence. New treatments have improved the prognosis for patients with advanced MM. Still, most patients do not respond, and the side effects can be severe, underlining the need for better therapies. LÄS MER

  3. 2. Optimized MRI methods for simplified oncological imaging in pancreas and liver

    Författare :Nikolaos Kartalis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Recent technological advances within the fields of Abdominal Imaging have revolutionised oncological imaging. In the investigation of the solid organs in the upper abdomen, extensive examinations are used in order to obtain accurate information. LÄS MER

  4. 3. Investigation of Water Mobility using Diffusion-Sensitive MRI: The Role of q-Space Imaging, High b-Values and Diffusion Time

    Författare :Jimmy Lätt; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; kurtosis; high b-value; diffusion; diffusion time; NMR; q-space;

    Sammanfattning : Nuclear magnetic resonance (NMR) diffusometry provides important information about molecular motion on a microscopic scale. The advantage of NMR diffusometry is its ability to characterise microstructures non-invasively. This has made the method important not only in chemistry, biochemistry and materials science, but also in medicine. LÄS MER

  5. 4. Middle Ear Cholesteatoma : Surgical Treatment, Follow-up and Hearing Restoration

    Författare :Lennart Edfeldt; Helge Rask-Andersen; Juha Silvola; Uppsala universitet; []
    Nyckelord :Oto-Rhino-Laryngology; Oto-rhino-laryngologi;

    Sammanfattning : Although middle-ear cholesteatoma is a major topic in otological research, its etiology and pathogenesis remain unclear. Pediatric cholesteatoma is considered more aggressive than adult cholesteatoma, as it has a higher rate of growth, is more often infected and exhibits wider extension. LÄS MER

  7. 5. The extent of gynaecological cancer : Evaluation, outcome and quality of life

    Författare :Björg Jónsdottir; Karin Stålberg; Inger Sundström Poromaa; Håkan Ahlström; Päivi Kannisto; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovarian cancer; endometrial cancer; cytoreductive surgery CRS ; PET MRI; MRI; Peritoneal cancer index PCI ; myometrial invasion MI ; quality of life.; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The overall aim of this thesis was to enhance treatment planning for gynaecological cancer patients and identify women that are more likely to have impaired quality of life (QoL) after treatment. In a retrospective cohort study on ovarian cancer, the peritoneal cancer index (PCI) was examined in relation to incomplete cytoreductive surgeries (CRS) and surgical complications (n=167).
