Patterns of care and outcomes of chemoradiation versus radiation alone for MGMT promoter unmethylated glioblastoma. This study says that for glioblastoma patients with unmethylated MGMT, adding Temodar to radiation does not improve survival or progression free survival. This is a retrospective study that does not control for other factors, but it is interesting. It opens the door for experimenting with other treatments for newly diagnosed MGMT unmethylated patients, such as perhaps substituting Val-083 instead of Temodar.
