|Condition or disease||Intervention/treatment||Phase|
|Brain Tumors and/or Solid Tumors Including Brain Stem Glioma High Grade CNS Tumors Ependymoma Medulloblastoma Craniopharyngioma Low Grade CNS Tumors Hodgkin Lymphoma Non Hodgkin Lymphoma Ewing Sarcoma Osteosarcoma Rhabdomyosarcoma Neuroblastoma Other||Drug: Methionine||Phase 2|
The study focuses on the following objectives:
- To estimate the success rate of Methionine (MET) for visualizing tumors at the time of diagnosis. The study hypothesizes that at least 70% of newly diagnosed tumors within each group will be studied and will be successfully visualized.
- To compare uptake of MET in tumors with tumor grade in patients with newly diagnosed or relapsed, and/or persistent disease. Hypothesis: high grade tumors will concentrate higher amounts of MET than lower grade tumors measured both qualitatively and semi-quantitatively.
- To examine the bio-distribution of MET in organs that do not contain tumor, in particular the lungs, heart, mediastinum, liver, spleen, pancreas, muscle, brain, and bone marrow.
- To compare the findings on MET PET scans with those of standard imaging modalities, principally MRI (magnetic resonance imaging) and FDG (fluorodeoxyglucose) PET CT (computed tomography) at diagnosis, or at study enrollment for patients with relapsed and or persistent disease, and for all patients over time.
- To compare the extent of abnormality on MRI with that of MET.
- To determine the presence or absence of elevated MET uptake beyond those of MRI defined abnormality.
- To explore the relationship between MET uptake and prognosis.

Participants who meet the eligibility criteria in the study will receive methionine.
- Success rate of methionine (MET) for visualizing tumors [ Time Frame: Baseline ]To estimate the success rate of methionine (MET) for visualizing tumors at the time of diagnosis. We hypothesize that at least 70% of tumors within each group studied will be successfully visualized.
- Association of methionine uptake with tumor grade [ Time Frame: End of study (maximum of 3 years post methionine infusion and PET scan) ]Methionine uptake in tumors will be compared among tumor grades in patients with newly diagnosed or relapsed, and/or persistent disease. Hypothesis: high-grade tumors will concentrate higher amounts of MET than lower-grade tumors measured both qualitatively and semi-quantitatively.
- Bio-distribution of MET in organs [ Time Frame: At baseline, after enrollment of the first 93 participants ]Whole body scans will be acquired and descriptive statistics for MET uptake from other parts of the body will be provided.
