  3. 3. The Identification and Characterisation of LRIG Gene Family and Its Expression in Astrocytic Tumours

    Author : Dongsheng Guo; Tomas Ekström; Umeå universitet; []
    Keywords : astrocytoma; brain; EGFR; LRIG; leucine-rich repeat; real-time RT-PCR; onkologi; Oncology;

    Abstract : Gliomas are the most common primary brain tumours, and their capacity to invade surrounding normal brain prevents complete removal of the tumour. Malignant glioma has still a poor prognosis. However, with the rapid development of molecular biology our understanding about glioma has increased dramatically. READ MORE

  4. 4. Qualities in the short life : psychological studies relevant to patient and spouse in malignant glioma

    Abstract : This thesis deals with psychological issues concerning patients with malignant gliomas, and their spouses. There is no known medical cure, and the patients have a limited survival expectancy. Therefore studies evaluating new treatment modes, an overall supportive atmosphere, and attempts to avoid imposing unnessesary strain are necessary. READ MORE
