Biopsy vs. extensive resection for first recurrence of glioblastoma: is a prospective clinical trial warranted?

BMC Research Notes
Christopher DardisNader Sanai

Abstract

Glioblastoma is an aggressive and almost universally fatal tumor. The prognosis at the time of recurrence has generally been poor, with overall survival typically in the range of 4-40 weeks. The merits of surgical resection (vs. open biopsy, to confirm recurrence via histology) in addition to conventional adjuvant chemotherapy have been the subject of longstanding debate. We wondered whether it would possible to conduct a trial at our institution to settle this question definitively with Class I evidence. Initially, we had hoped to conduct a randomized, unblinded prospective clinical trial. However on closer inspection it appeared that such an undertaking would pose significant practical challenges. Thus we present our protocol in draft form. In keeping with recommended outcomes for these tumors, the primary endpoint would be median progression free survival. Secondary end points would be: median overall survival (mOS, from time of recurrence) and change in Karnofsky Performance Status over time. Patients would be eligible at the time of first recurrence if they had received conventional treatment until that point and at least 1 month had elapsed since the time of radiation. All patients would be considered potentially eligible...Continue Reading

Cancer Stem Cells in Glioblastoma

Glioblastoma is the most common and aggressive type of brain tumor. It contains a population of tumor initiating stem cell-like cells known as cancer stem cells. Investigations are ongoing into these cancer stem cells found in these solid tumors which are highly resistance to treatment. Here is the latest research on cancer stem cells in glioblastoma.
