Survival benefit of concomitant chemoradiation in adult supratentorial primary glioblastoma. A propensity score weighted population-based analysis.

This population-based propensity-score study with long-term follow-up suggests that the implementation of the Stupp protocol in 2005 had a positive impact on the survival of patients with supratentorial GBM. This "real-world" analysis validates the results of the original randomized control trial on which this protocol is based.
