Basic Information

• Recruitment Status: COMPLETED

Brief Summary

To determine if FDOPA-PET/MRI imaging can predict response to treatment of bevacizumab.

Detailed Description

Evaluate the feasibility of using FDOPA-PET/MRI pediatric patients with CNS tumors. Positive results in this small study would provide the data needed to expand the study to validate the use in a larger population of pediatric patients. Validating the use of FDOPA-PET imaging as an early predictor for response to anti-angiogenic therapy could greatly impact the standard of care for treating and evaluating pediatric brain tumors and provide a useful biomarker for assessing experimental therapeutics.

• Patient must be ≤ 21 years of age at time of study enrollment.
• Patient must have measurable residual disease, defined as tumor that is measurable in two perpendicular diameters on MRI. Diffuse leptomeningeal disease is not considered measurable.
• Patient must have a Lansky or Karnofsky performance of >40% corresponding to ECOG categories 0, 1, or 2. Karnofsky will be used for patients >16 years of age and Lansky for patients <16 years of age. Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
• Patient must have a life expectancy of >8 weeks.
• Patient must have fully recovered from the acute toxic effects of all prior chemotherapy or radiation prior to entering this study.
• Patient must have recovered from any surgical procedure before enrolling on this study.
• Hypertensive patients are eligible provided the hypertension is well controlled (95th percentile for age and height if patient ≤17 years) on stable doses of medication. (See Appendices I and II for tables of blood pressure based on age and gender).
• Patients receiving corticosteroids are eligible provided the dose is stable or decreasing for at least 7 days.
• Patient must have adequate bone marrow function (including status post-SCT) defined as:

1. Peripheral absolute neutrophil count (ANC) ≥1000/uL (must not have received G-CSF within the prior 7 days)

2. Platelet count ≥ 100,000/uL (transfusion independent)

3. Hemoglobin ≥ 8.0 gm/dL (may receive pRBC transfusions)

• Patient must have adequate renal function defined as:

1. Creatinine clearance or radioisotope GFR ≥70ml/min/1.73 m2 or

2. A serum creatinine based on age/gender as follows:

• 1 month to < 6 months, male max 0.4, female max 0.4
• 6 months to < 1 year, male max 0.5, female max 0.5
• 1 to <2 years, male max 0.6, female max 0.6

• 16 years, male max 1.7, female max 1.4
• Urine protein should be screened by dipstick analysis. If protein ≥ 2+ on dipstick, then Urine Protein Creatinine (UPC) ratio should be calculated. If UPC ratio >1, 24-hour urine protein should be obtained and the level should be <1000 mg/24 hours for patient enrollment.

Note: UPC ratio of spot urine is an estimation of the 24 hour urine protein excretion- a UPC ratio of 1 is roughly equivalent to a 24-hour urine protein of 1 gm. UPC ratio is calculated using of the following formulae:

[urine protein]/[urine creatinine] - if both protein and creatinine are reported in mg/dL [(urine protein x 0.088]/[urine creatinine] - if urine creatinine is reported in mmol/L
