OBJECTIVE: The aim of this study was to assess the clinical effectiveness of sodium fluorescein-guided microsurgery in patients with high-grade gliomas.

PATIENTS AND METHODS: 120 patients with high-grade gliomas who were hospitalized in our Neurosurgery Department from January 2018 to January 2021 were selected and then divided into a control and a study group using the random number table method, with 60 cases in each group. To compare the clinical efficacy of patients in both groups, neuronavigation microsurgery was used in the control group and neuronavigation microsurgery combined with sodium fluorescein-guided microsurgery was used in the study group.

RESULTS: The Gross Total Resection Rate (GTRR) of the study group was significantly higher than that of the control group. There was no significant difference in intraoperative bleeding loss or hospital stay between the two groups, and the study group had a much shorter operation time than the control group. The Karnofsky Performance Score (KPS) and the National Institutes of Health Stroke Scale (NIHSS) scores did not significantly differ between the two groups prior to surgery but declined significantly in the study group compared to the control group following treatment. In terms of adverse effects, there was no significant difference between the two groups. In the control group, the median progression-free survival (PFS) was 7.5 months, and the median overall survival (OS) was 9.6 months, whereas in the study group, the median PFS was 9.5 months, and the median OS was 11.5 months. PFS did not significantly differ between the two groups (HR=1.389, 95% CI=0.926-2.085, p=0.079); however, OS was significantly higher in the study group compared to the control group (HR=1.758, 95% CI=1.119-2.762, p=0.013).

CONCLUSIONS: Fluorescein-guided microsurgery can dramatically improve total resection rate, postoperative neurological functional status, and overall survival with higher efficacy and safety in patients with high-grade gliomas.
