Official title

A Pilot, Non-Therapeutic NeuroImaging Study of 18F-FLT in Pediatric Patients With Newly Diagnosed Central Nervous System Tumors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In spite of numerous advances in neuroimaging techniques, the diagnosis of pediatric brain tumors relies on the pathologic evaluation of material obtained at the time of the initial operation. While 18F-FDG-positron emission tomography (PET) helps identify higher-grade lesions due to their increased glucose metabolism, the high tracer uptake of the normal adjacent brains makes this modality of limited value. Fluorine-18 fluorothymidine (FLT) is a new imaging agent that has two significant advantages in the imaging of CNS tumors. First, this agent detects cellular proliferation directly, and second, the normal brain does not take up the agent, making a positive area(s) easy to identify. Before embarking on a large pediatric disease stratified assessment of FLT imaging in pediatric neurooncology patients, the investigators are proposing a limited patient pilot study to evaluate the biodistribution, dosimetry and specificity of this compound when compared to immunohistochemical assessment of mitotic activity in newly diagnosed patients undergoing surgical resection.
