Using special MRI to detect inflammation in brain tumors

USPIO Enhanced MR Imaging in CNS Tumours (UMIC) : A Pilot Study of Ferumoxytol (Feraheme ©) as an Imaging Biomarker of Tumour Associated Macrophage (TAM) Infiltration in Vestibular Schwannoma (VS) and Transforming Low Grade Glioma (LGG)

Not applicable Interventional Northern Care Alliance NHS Foundation Trust · NCT06572475

This study is testing a special MRI technique that uses a contrast agent to see if it can help doctors spot inflammation in brain tumors like vestibular schwannomas and gliomas.

What this trial studies

This study evaluates the use of ultrasmall superparamagnetic iron oxide (USPIO) enhanced magnetic resonance imaging (MRI) to measure the abundance of tumor-associated macrophages in central nervous system tumors, specifically vestibular schwannomas and gliomas. By injecting USPIO into patients, the imaging technique aims to visualize and quantify the inflammatory response within the tumor, which may have implications for prognosis and treatment. The study focuses on determining the feasibility and effectiveness of this imaging method in a clinical setting.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 16 and older with a suspected CNS tumor of the specified types who can remain still during the imaging process.

Not a fit: Patients with a life expectancy of less than one year, previous CNS radiotherapy, or certain medical conditions that contraindicate MRI will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a non-invasive method to assess tumor inflammation, potentially guiding treatment decisions for patients with brain tumors.

How similar studies have performed: While the use of USPIO in MRI is a novel approach, similar imaging techniques have shown promise in other studies for assessing inflammation in tumors.
