The presence of stem cell characteristics in glioma cells raises the possibility that mechanisms promoting the maintenance and self-renewal of tissue specific stem cells have a similar function in tumor cells. Here we characterized human gliomas of various malignancy grades for the expression of stem cell regulatory proteins. We show that cells in high(More)
OBJECTIVE Neuronavigational devices have traditionally used preoperative imaging with limited possibilities for adjustment to brain shift and intraoperative manipulation of the surgical lesions. We have used an intraoperative imaging and navigation system that uses navigation on intraoperatively acquired three-dimensional ultrasound data, as well as(More)
PURPOSE Cells in the ependymal region in the adult central nervous system (CNS) have been found to possess neural progenitor cell (NPC) like features including capacity for generating new neurons and glia in response to injury and inflammatory disease. Whether these cells are activated after a peripheral nerve injury has not previously been extensively(More)
Glioblastoma multiforme (GBM) represent the most aggressive brain tumor with a median overall survival of about 12-15 months. Over 90% of GBM tumors have recently been shown to be infected with human cytomegalovirus (HCMV). In this case-control study, we evaluated whether there was an association between the grade of HCMV infection and long-term survival (>(More)
OBJECTIVE The current study retrospectively assessed delayed gamma knife radiosurgery (GKRS) in the management of high-grade glioma recurrences. METHODS A total of 55 consecutive patients with high-grade glioma comprising 68 World Health Organization (WHO) III and WHO IV were treated with GKRS for local recurrences between 2001 and 2007. All patients had(More)
BACKGROUND Swedish health care legislation requires equal, high-quality health care for all inhabitants, while regional differences of medical availability and treatment potentially allow for different outcomes. This study was undertaken to evaluate whether glioma survival differed between the Stockholm region and the other Swedish regions since the(More)
