Baseline characteristics, intraoperative blood loss, surgery duration, resection extent, and postoperative complications were documented.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The duration of surgery was significantly shorter in the fluorescein group than in the non-fluorescein group (P = 0.022), especially in patients with tumors in the occipital lobes (P = 0.013). More critically, the gross total resection (GTR) rate was significantly higher in the fluorescein group than in the non-fluorescein group (45.9% vs. 19.6%, P = 0.003). The postoperative residual tumor volume (PRTV) was also significantly lower in the fluorescein group than in the non-fluorescein group (0.40 [0.12-7.11] cm<jats:sup>3<\/jats:sup> vs. 4.76 [0.44-11.00] cm<jats:sup>3<\/jats:sup>, P = 0.020).

This technique is particularly advantageous for patients with tumors located in non-verbal, sensory, motor, and cognitive areas such as the temporal and occipital lobes, and does not increase the incidence of postoperative complications.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fonc.2023.1191470","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T11:37:28Z","timestamp":1685705848000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Fluorescein-guided
