Fludeoxyglucose F 18 Positron Emission Tomography and Magnetic Resonance Perfusion Imaging in Patients With Neurofibromatosis 1 and Plexiform Neurofibroma
Recruitment status was Recruiting
RATIONALE: New imaging procedures such as fludeoxyglucose F 18 positron emission tomography (FDG-PET) and magnetic resonance (MR) perfusion imaging may improve the ability to detect disease progression, help doctors predict a patient's response to treatment, and help plan the most effective treatment.
PURPOSE: This diagnostic trial is studying how well FDG-PET and MR perfusion imaging work in finding disease progression and determining response to treatment in patients with neurofibromatosis 1 and plexiform neurofibroma.
Neurofibromatosis Type 1

|Study Design:||Masking: Open Label
Primary Purpose: Diagnostic
|Official Title:||Novel Imaging Modalities For Plexiform Neurofibromas|
- Tumor progression as measured by tumor area and volume at 1 year [ Designated as safety issue: No ]
|Study Start Date:||April 2002|
|Estimated Primary Completion Date:||December 2010 (Final data collection date for primary outcome measure)|
- Determine whether fludeoxyglucose F 18 positron emission tomography (FDG-PET) and MR perfusion studies can predict plexiform neurofibroma growth rates in patients with neurofibromatosis 1.
- Determine whether FDG-PET and MR perfusion studies can predict the likelihood of response in patients who are undergoing investigational treatment for plexiform neurofibromas.
- Identify neuroimaging characteristics that distinguish patients who have responded to therapy from those who have not after completion of treatment.
- Stratum 1: Patients undergo MR perfusion scan with gadopentetate dimeglumine and fludeoxyglucose F 18 positron emission tomography (FDG-PET) at baseline and quantitative MRI evaluation at baseline and 1 year.
- Stratum 2: Patients undergo quantitative MRI, MR perfusion scan with gadopentetate dimeglumine, and FDG-PET at baseline and 1 year.
PROJECTED ACCRUAL: A total of 48 patients (32 for stratum 1 and 16 for stratum 2) will be accrued for this study.
