|Brief Title||Using Positron Emission Tomography to Predict Intracranial Tumor Growth in Neurofibromatosis Type II Patients|
|Official Title||Using Positron Emission Tomography (PET) to Predict Intracranial Tumor Growth in Neurofibromatosis Type II (NF2) Patients|
- To use magnetic resonance imaging and positron emission tomography to better understand the growth of brain tumors in people with neurofibromatosis type II.
- Individuals between 18 and 50 years of age who have been diagnosed with NF2 and have at least three untreated intracranial tumors.
The objective of this prospective observational study of intracranial tumors in patients with neurofibromatosis type 2 (NF2) is to gain insight into the use of 18F-fluoro-deoxyglucose (FDG) and 3 -deoxy-3 -18F-fluorothymidine (FLT) positron emission tomography (PET)/computed tomography (CT) as a predictive measure of future tumor growth patterns.
STUDY POPULATION: <TAB>
Twelve patients, ages 18-50, with a clinical or genetic diagnosis of NF2 and harboring at least 3 unoperated intracranial tumors (meningiomas and/or vestibular schwannomas) will participate in this study.
Study participants will be evaluated with a thorough physical and neurologic examination upon enrollment. This initial outpatient evaluation will include contrast-enhanced magnetic resonance imaging (MRI) of the brain, FDG-PET/CT and FLT-PET/CT scans.
Subjects will be followed as outpatients for two years, during which time MRI evaluation will be performed every six months.
Based on data derived from this study, we hope to correlate FDG-PET/CT and FLT-PET/CT scans with metabolic activity and cellular proliferation within tumors. These findings will help us better forecast tumor growth and senescence. These findings should permit the safer treatment of the subset of tumors that will grow and cause symptoms and avoid the unnecessary treatment of lesions that will remain stable (not requiring treatment) in these patients.
