Effect of stRess and exeRcize on the Outcome After Chemo-Radiation

Glioblastoma (GBM) is a highly malignant, incurable primary brain tumor. Due to the nature of this disease and the extent of the treatment (surgery followed by chemoradiation according to the Stupp trial) patients undergo considerable psychological distress. It is known that stress hormones are involved in a wide range of processes involved in cell survival, cell cycle and immune function, and can cause therapy resistance. In this study the effect of stress on outcome after chemoradiation in patients with GBM will be investigated.
