【 摘 要 】

Background: Glioblastoma multiforme (GBM) is one of the most deadly cancers in humans. Despite recent advances in anti-cancer therapies, most patients with GBM die from local disease progression. Fluorescence image guided surgical resection (FIGR) was recently advocated to enhance local control of GBM. This is meta-analyses of 5-aminolevulinic (5-ALA) induced FIGR. Materials: Review of the literature produced 503 potential publications; only 20 of these fulfilled the inclusion criteria of this analysis, including a total of 565 patients treated with 5-ALA-FIGR reporting on its outcomes and 800 histological samples reporting 5-ALA-FIGR sensitivity and specificity. Results: The mean gross total resection (GTR) rate was 75.4% (95% CI: 67.4–83.5, p < 0.001). The mean time to tumor progression (TTP) was 8.1 months (95% CI: 4.7–12, p < 0.001). The mean overall survival gain reported was 6.2 months (95% CI: −1–13, p < 0.001). The specificity was 88.9% (95% CI: 83.9–93.9, p < 0.001) and the sensitivity was 82.6% (95% CI: 73.9–91.9, p < 0.001). Conclusion: 5-ALA-FIGR in GBM is highly sensitive and specific, and imparts significant benefits to patients in terms of improved GTR and TTP.
