Fludeoxyglucose F 18 Positron Emission Tomography and Magnetic Resonance Perfusion Imaging in Patients With Neurofibromatosis 1 and Plexiform Neurofibroma - Full Text View

Sponsored by:	Children's Hospital of Philadelphia
Information provided by:	National Cancer Institute (NCI)
ClinicalTrials.gov Identifier:	NCT00060008

Purpose

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.

Primary Outcome Measures:

Tumor progression as measured by tumor area and volume at 1 year [ Designated as safety issue: No ]

Estimated Primary Completion Date:	December 2010 (Final data collection date for primary outcome measure)

Detailed Description:

OBJECTIVES:

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.

OUTLINE:

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.

Criteria

DISEASE CHARACTERISTICS:

Stratum 1:
- Diagnosis of neurofibromatosis 1 (NF1) and plexiform neurofibromas
- At high risk for progression, as defined by any of the following:
  - Anatomic location such that progression carries a high risk of impairment of function, pain, or disfigurement (e.g., neck/mediastinum, paraspinal nerve roots, orbit, and face)
  - Tumors that the patient, family, or caregiver believes have increased in size within the past year, but appear stable by standard clinical or radiographic measures
- No plexiform neurofibromas that are small, cause no pain or functional impairment, or are not likely to cause pain or functional impairment over the succeeding 12 months
Stratum 2:
- Diagnosis of NF1 and progressive plexiform neurofibromas
  - Neurofibroma progression documented by increase in lesion size on MRI
- Currently being enrolled on a clinical therapeutic trial at Children's Hospital of Philadelphia
