IV sodium fluorescein to highlight suspected CNS tumors during surgery

Official title: Use of i.v. Sodium Fluorescein as a Fluorescent Intra-operative Tracer in Patients With Suspected Malignant Neoplasms of the CNS

Run by Fondazione I.R.C.C.S. Istituto Neurologico Carlo Besta · NCT07233954 · Data updated 2026-11-12

This study tests whether giving a small IV dose of sodium fluorescein during surgery helps surgeons see and remove suspected malignant brain and spinal tumors in people of any age.

Is this trial a fit for you?

Likely a good fit

People of any age with a contrast-enhancing suspected aggressive CNS lesion on pre-operative MRI or CT who can give informed consent and do not have listed exclusions are ideal candidates.

Probably not a fit

Patients with non–contrast-enhancing or diffuse infiltrative tumors, those with known severe allergy to fluorescein or contrast agents, recent myocardial infarction or stroke, severe renal or hepatic failure, or women in the first trimester of pregnancy or who are lactating may not benefit or be eligible.

What this trial studies

The FLUO.CER.TUM study is a prospective observational project at the IRCCS Istituto Neurologico Carlo Besta in Milan enrolling about 800 patients with contrast-enhancing suspected aggressive CNS lesions. Each participant receives 5 mg/kg of intravenous sodium fluorescein at induction of anesthesia and undergoes fluorescence-guided resection using a surgical microscope equipped with a dedicated fluorescence filter. Pre- and post-operative imaging and clinical/neurological evaluations are performed to document extent of resection and perioperative outcomes. Safety data and intraoperative observations are collected without altering standard surgical management.

Why it matters

Potential benefit: If successful, this approach could help surgeons remove more tumor tissue while better sparing healthy brain, potentially improving clinical outcomes.

How similar studies have gone: Previous observational and some comparative studies have reported improved intraoperative tumor visualization and greater extent of resection with fluorescein in contrast-enhancing brain tumors, though randomized evidence is limited.
