Use of Fluorescence in Gliomas

Use of Fluorescence in High-Grade Gliomas

Source: ClinicalTrials.gov · Last updated 30 Mar 2026

Brief summary (registry, in English)

During brain tumor surgery, it can be difficult for surgeons to distinguish between tumor tissue and healthy brain tissue. To address this challenge, fluorescent agents such as sodium fluorescein or 5-ALA are sometimes used. These substances cause the tumor to "glow" under specific lighting conditions, making it easier to visualize. This study retrospectively analyzes medical records of patients treated at the University Hospital of Alessandria between June 2023 and March 2024. It compares surgeries performed with these fluorescent agents to those performed without them, in order to determine whether fluorescence-guided surgery leads to a higher rate of complete tumor removal (gross total resection), as confirmed by post-operative MRI scans. The aim is to evaluate how the use of fluorescent dyes (fluorochromes) influences surgical outcomes in patients with high-grade gliomas (aggressive brain tumors). The study will also assess the impact of these tools on operative time, patient safety, and the overall recovery process.
