Stellenwert der Tumorresektion in der interdisziplinären Behandlung hirneigener Tumoren

High grade gliomas, i.e. anaplastic tumors and glioblastomas, are the most common primary intrinsic brain tumors in adulthood, followed by diffuse infiltrating WHO grade II gliomas. The importance of surgical resection of these high grade tumors with respect to overall survival is evidenced by recent studies. For low grade tumors high quality studies are still pending, however, there is increasing evidence for a beneficial effect of tumor resection with respect to malignant tumor progression and overall survival.
