Summary
Brief summary (as posted)
Patients with recurrent Glioblastoma (GBM) are commonly presented to surgeons, along with the question of whether or not to re-resect the recurrence. There is no Level 1 evidence to support a role for repeat surgery in this context, but a multitude of observational research suggests that repeat surgery may improve quality survival. Unfortunately, these studies all suffer from selection bias. The goal of this study is to provide a care trial context to help neurosurgeons manage patients presenting with recurrent GBM, with no additional risks, tests, or interventions than what they would normally encounter in routine care. Secondary goals include a test of the hypothesis that repeat resection can improve median overall survival, and that it can increase the number of days of survival outside of a hospital/nursing/palliative care facility.
