Clinical Trial Summary

This phase II trial studies how well F-18 fluoroethyltyrosine (fluoroethyltyrosine) works in detecting tumors in participants with intracranial tumors that have come back. FET accumulates in malignant cells within intracranial neoplasms and can be used to detect recurrent disease and characterize the grade of glial neoplasms. Imaging agents such as FET can help oncologist to see the tumor better during a positron emission tomography (PET) scan.


Clinical Trial Description

PRIMARY OBJECTIVES: I. To determine if F-18 fluoroethyltyrosine (FET) PET can differentiate between benign treatment-related changes and recurrence in comparison to pathology in population 1 with recurrent metastatic disease and high-grade gliomas. II. To determine if FET PET can accurately differentiate between low-grade and high-grade gliomas in population 2. SECONDARY OBJECTIVES: I. To determine if FET PET can differentiate between benign treatment-related changes and recurrence in comparison to pathology or imaging follow-up in population 1. II. To determine if FET PET can differentiate between benign treatment-related changes and recurrence in comparison to pathology in population 1 with recurrent low-grade gliomas. OUTLINE: Participants receive F-18 fluoroethyltyrosine intravenously (IV) over approximately 1 minute and undergo PET over 40 minutes. After completion of study treatment, participants are followed up periodically. ;
