It is important to distinguish primary glioblastoma from secondary glioblastoma. Multiple Weibel-Palade bodies, normally absent in the brain endothelial cells, can be found in the cells of the newly formed vessels. The participation of sex hormones and viruses in its oncogenesis was also suggested.

Prognostic factors Selection of an appropriate made of treatment and prognosis in patients suffering from GBM depend on the tumor location, its histological grade, genetic profile, proliferative index, completeness of surgery resection and the patient’s age and position on the Karnofsky performance status scale KPS [ 80 ] before radiotherapy [ 81 ].
