Brief Summary

The purpose of this study is to test the usefulness of imaging with radiolabeled methionine in the evaluation of children and young adults with tumor(s). Methionine is a naturally occurring essential amino acid. It is crucial for the formation of proteins. When labeled with carbon-11 (C-11), a radioactive isotope of the naturally occurring carbon-12, the distribution of methionine can be determined noninvasively using a PET (positron emission tomography) camera. C-11 methionine (MET) has been shown valuable in the monitoring of a large number of neoplasms. Since C-11 has a short half life (20 minutes), MET must be produced in a facility very close to its intended use. Thus, it is not widely available and is produced only at select institutions with access to a cyclotron and PET chemistry facility. With the new availability of short lived tracers produced by its PET chemistry unit, St. Jude Children's Research Hospital (St. Jude) is one of only a few facilities with the capabilities and interests to evaluate the utility of PET scanning in the detection of tumors, evaluation of response to therapy, and distinction of residual tumor from scar tissue in patients who have completed therapy. The investigators propose to examine the biodistribution of MET in patients with malignant solid neoplasms, with emphasis on central nervous system (CNS) tumors and sarcomas. This project introduces a new diagnostic test for the noninvasive evaluation of neoplasms in pediatric oncology. Although not the primary purpose of this proposal, the investigators anticipate that MET studies will provide useful clinical information for the management of patients with malignant neoplasms.

Outcome Measures

Primary Outcomes (1)

  • Success rate of methionine (MET) for visualizing tumors

    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.

    Baseline

Secondary Outcomes (2)

  • Association of methionine uptake with tumor grade

    End of study (maximum of 3 years post methionine infusion and PET scan)

  • Bio-distribution of MET in organs

    At baseline, after enrollment of the first 93 participants

Study Arms (1)

Participants

EXPERIMENTAL

You may qualify if:

  • All participants under the care of St. Jude physicians with known or suspected neoplastic disease are eligible for participation.
  • Participants will have had, or are scheduled to have clinical imaging evaluations which may include FDG PET CT, or CT, or MRI within 4 weeks of entry.
  • No limit on age or gender.
  • Female participants of childbearing age must not be lactating due to theoretical potential harm to the infant from exposure to radiation.
  • Informed consent signed by participant, parent, or guardian according to the guidelines of the institutional review board.

You may not qualify if:

  • More than 6 MET PET scans within the previous 12 months.
  • Inability or unwillingness of research participant, parent, or legal guardian/representative to give written informed consent.
  • All participants under the care of St. Jude physicians with known or suspected neoplastic disease are eligible for participation.
