Molecular Genetic, Host-derived and Clinical Determinants of Long-term Survival in Glioblastoma

This pro - and retrospective multicenter clinical epidemiological study studies the molecular genetic, host-derived and clinical determinants of glioblastoma patients with an overall survival of more than 5 years. The different research focusses are: * Identification of clinical parameters and patient characteristics / host-related factors in long-term survivors (Focus 1) * Identification of molecular tumor characteristics in long-term survivors (Focus 2) * Assessment of therapy-related parameters, including neuro-toxicity (Focus 3) * Immunological studies (Focus 4)
