Operative techniques for gliomas and the value of extent of resection
Sanai N et al. – A review of the operative techniques for gliomas and the value of extent of resection reports that, despite persistent limitations in the quality of available studies, a more extensive surgical resection is associated with longer life expectancy for both low-grade and high-grade gliomas. Methods- Review of operative techniques and value of extent of resection for gliomas
- Analysis of modern intraoperative mapping techniques
- Assessment of every major clinical publication since 1990 on the role of resection extent in glioma outcome
Results- Cortical language mapping: safe and efficient adjunct to optimize tumor resection while preserving essential language sites, even in the setting of negative mapping data
- Unclear value of maximizing glioma resections; no general consensus for efficacy of the extent of glioma resection in improving pt outcome
- Clear importance of resection in obtaining tissue diagnosis and alleviating symptoms
- Lack of class I evidence for assessing influence of extent of resection
