Potential and Pitfalls of Postoperative Volumetric Assessment of Extent of Resection in High-Grade Glioma in Resource-Constrained Settings.

Logistic difficulties impede routine implementation of this protocol in developing countries. MRI volumetry is clearly more accurate than surgeons' intraoperative estimation of EOR. Notwithstanding the role of EOR in survival, our study reveals a perhaps bigger impact of tumor biology and postoperative functional status in this equation.
