GliaSite Brachytherapy Boost as Part of Initial Treatment of Glioblastoma Multiforme: A Retrospective Multi-Institutional Pilot Study

Conclusion: The results of this analysis have demonstrated that dose escalation (>100 Gy) with GliaSite is well tolerated and associated with minimal toxicity. Local control improved with the use of GliaSite brachytherapy. The putative survival advantage seen in this study needs to be interpreted with caution; nevertheless, the data provide sufficient justification to investigate the potential role of radiation dose escalation in conjunction with GliaSite in the initial treatment of glioblastoma multiforme.
