    Sammanfattning : Aim: To study the possibility of detecting lymph node metastasis in locally advanced urinary bladder cancer (UBC) treated with radical cystectomy (RC) by using preoperative positron emission tomography/computed tomography (PET/CT) and peroperative sentinel node biopsy (SNB) technique. We also investigate the clinical significance of macrophage traits expression by cancer cells, M2-macrophage infiltration (MI) in tumor stroma and the immunohistochemical expression of biomarkers in cancer cells in relation to clinicopathologic data.

    Sammanfattning : The two purposes of this thesis were to evaluate new diagnostic techniques of lymphnode staging in invasive bladder cancer and to evaluate the results of neoadjuvant chemotherapy in invasive bladder cancer.Sentinel node detection was performed in 13 patients in preparation for radical cystectomy.

  4. 28. Application of nuclear medicine methods in patients with breast cancer

    Författare :Brigitte Wilczek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Breast neoplasm; neoadjuvant chemotherapy; radionuelide investigation; sentinel node; SPECT;

    Sammanfattning : While physical examination, mammography and aspiration cytology or core biopsy form the basis in the diagnosis of breast cancer, additional examinations are sometimes required in the evaluation of unclear breast masses. The study deals with the application and evaluation of different nuclear medicine techniques in the diagnosis and treatment of breast cancer. LÄS MER

  5. 29. Development of Magnetomotive Ultrasound Imaging

    Författare :Maria Evertsson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetomotive ultrasound; molecular imaging; contrast angents; multimodal imaging; sentinel lymph node;

    Sammanfattning : The earlier abnormalities coupled with disease can be discovered in the body, the larger is the chance to survive the disease. Molecular imaging is a growing research field which aims to detect these abnormalities at a molecular level, when the chance of survival is still high. LÄS MER

  7. 30. Nuclear medicine imaging of breast cancer and regional lymph nodes

    Författare :Rimma Danielsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :breast neoplasm; scintimammography; diagnostic accuracy; triple diagnosis; axillary lymph node metastases;

    Sammanfattning : The aim of this thesis was to explore the role of nuclear medicine in diagnosis of primary breast carcinoma and regional lymph node involvement. The introduction includes a review over nuclear medicine techniques currently under investigation. LÄS MER
