  1. 6. ARCON in experimental and clinical radiotherapy

    Författare :Ana Maria Rojas Callejas; Björn Zackrisson; René-Olivier Mirimanoff; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; ARCON; tumours; normal tissues; radiosensitization; carbogen; nicotinamide; repair inhibition; therapeutic gain; rodents; humans; Onkologi; Oncology; Onkologi; onkologi; Oncology;

    Sammanfattning : xHypoxia and repopulation of tumour clonogens are two important determinants of treatment outcome in radiotherapy. In general clinical evidence indicates that loco-regional control may be reduced with long overall treatment times and for tumours with low pre-treatment levels of oxygen. LÄS MER

  3. 7. Human secretoglobins in normal and neoplastic cells and tissues

    Författare :Anna Sjödin; Håkan Hedman; Roger Henriksson; Mårten Fernö; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; secretoglobins; mammaglobin; lipophilin; breast cancer; pituitary; sweat gland; Onkologi; Oncology; Onkologi; onkologi; Oncology;

    Sammanfattning : Secretoglobins is a newly described polypeptide family that has gained a lot of interest in human cancer and inflammation research. Although the first secretoglobin polypeptide was discovered more than 30 years ago, their physiological function is still not known. LÄS MER

  4. 8. Risk and prognostic factors for malignant glioma

    Författare :Sara Sjöström; Beatrice S Melin; Ulrika Andersson; Monika Hegi; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; Glioblastoma; Risk; Outcome; EGR; EGFR; VEGF; VEGFR; DNA repair; virus; Oncology; Onkologi; onkologi; Oncology;

    Sammanfattning : Background: Glioblastoma is the most common and aggressive type of glioma and associated with poor prognosis. Apart from ionizing radiation and some rare genetic disorders, few aetiological factors have been identified for primary brain tumours. LÄS MER

  5. 9. Radiolabeled acetate PET in oncology imaging : studies on head and neck cancer, prostate cancer and normal distribution

    Författare :Aijun Sun; Jens Sörensen; Silvia Johansson; Mikael Karlsson; Katrine Åhlström Riklund; Ingela Turesson; Heikki Minn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11C-acetate; 18F-fluoroacetate; PET; head and neck cancer; staging; delineating tumor volume; clearance rate; perfusion; RT; treatment outcome; benign and malignant lymph node; prostate cancer; normal distribution; Oncology; Onkologi; onkologi; Oncology;

    Sammanfattning : The use of positron emission tomography (PET) for imaging in oncology has grown rapidly in recent years. 2-[18F]-fluorodeoxyglucose (FDG) is the most common tracer of PET, although drawbacks exist. LÄS MER

  7. 10. Expression and prognostic value of LRIG1 and the EGF-receptor family in renal cell and prostate cancer

    Författare :Marcus Thomasson; Håkan Hedman; Roger Henriksson; Börje Ljungberg; Sten Nilsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; Renal cell carcinoma; EGFR; ErbB1-4; LRIG1; Oncology; Onkologi; onkologi; Oncology;

    Sammanfattning : The epidermal growth factor receptor (EGFR) family consists of four (EGFR, ErbB2, Erbb3, and ErbB4) receptor tyrosine kinases (RTK) whose signalling is important for physiological and malignant cellular functions such as proliferation, survival, migration, and differentiation. EGFR and ErbB2 in particular are established oncogenes in many solid tumours and are targets for anti-cancer treatment. LÄS MER
