Outcome comparisons of high-grade glioma resection with or without fluorescein sodium-guidance.

PURPOSE: To compare surgical outcomes and adverse events between patients received microsurgical resection of high-grade gliomas with or without fluorescein sodium-guidance.

PATIENTS: A retrospective study was conducted in our hospital between June 2016 and January 2017. Patients were divided into 2 groups: Fluorescein Group (42 patients) and Nonfluorescein Group (40 patients).

MEASUREMENTS: Intraoperative (hemorrhage value and operation time) and postoperative (consistency between fluorescence-stained tissue and histopathological results, rate of resection) measurements were documented. Postoperative adverse events were recorded. Patients were followed up for 6 months to evaluate postsurgery glioma recurrence.

MAIN RESULTS: Intraoperatively, hemorrhage value, and operation time were significantly less in Fluorescencein than in Nonfluorescencein group. The rate of glioma complete resection was significantly higher in Fluorescencein than in Nonfluorescencein group (85.7%vs 62.5%, P = 0.02). The rate of glioma recurrence was significantly lower in Fluorescencein than in Nonfluorescencein group (11.9%vs 25.0%, P = 0.01), and no significant differences on adverse events were observed.

CONCLUSIONS: Intraoperative fluorescein sodium-guidance could facilitate the complete resection and significantly decrease the postoperative recurrence in patients with high-grade gliomas.
