Meta Analysis
Prognostic implications of resection extent for patients with glioblastoma multiforme: a meta-analysis.
Surgery is the primary treatment of glioblastoma multiforme (GBM), and a greater extent of resection (EOR) has been shown to be associated with improved survival. Our objective was to perform a meta-analysis comparing the 1-year overall survival (OS) and 1-year progression-free survival (PFS) of GBM patients who receive total resection, incomplete resection, or biopsy only. ⋯ Total resection of GBM is associated with improved OS and PFS as compared to incomplete resection or biopsy.
