    • Leptomeningeal lesions that do not meet the measurements noted above

• Patients must have a Lansky or Karnofsky performance status score of >= 50, corresponding to Eastern Cooperative Oncology Group (ECOG) categories 0, 1 or 2; use Karnofsky 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
• Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study

• Patients must have received standard treatment appropriate for their tumor type

  • Myelosuppressive chemotherapy: patients with solid tumors must not have received myelosuppressive chemotherapy within 3 weeks of enrollment onto this study (6 weeks if prior nitrosourea)
  • Hematopoietic growth factors: at least 14 days must have elapsed after receiving pegfilgrastim and least 7 days must have elapsed since the completion of therapy with a non-pegylated growth factor
  • Biologic (anti-neoplastic agent): at least 7 days must have elapsed since completion of therapy with a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period prior to enrollment must be extended beyond the time during which adverse events are known to occur
  • Monoclonal antibodies: at least 3 half-lives must have elapsed since prior therapy that included a monoclonal antibody
  • Radiotherapy: >= 2 weeks must have elapsed since local palliative external beam radiation therapy (XRT) (small port); >= 6 weeks must have elapsed since treatment with therapeutic doses of MIBG; >= 3 months must have elapsed if prior craniospinal XRT was received, if >= 50% of the pelvis was irradiated, or if total body irradiation (TBI) was received; >= 6 weeks must have elapsed if other substantial bone marrow irradiation was given
  • Stem cell transplant or rescue without TBI: no evidence of active graft vs. host disease and >= 2 months must have elapsed since transplant
• For patients with solid tumors without bone marrow involvement: peripheral absolute neutrophil count (ANC) >= 1000/uL
• For patients with solid tumors without bone marrow involvement: platelet count >= 100,000/uL (transfusion independent, defined as not receiving platelet transfusions within a 7 day period prior to enrollment)
• For patients with solid tumors and known bone marrow metastatic disease: peripheral absolute neutrophil count (ANC) >= 750/uL
• For patients with solid tumors and known bone marrow metastatic disease: platelet count >= 75,000/uL (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)

• Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 or a serum creatinine based on age/gender as follows:

  • Age 1 to < 2 years: maximum serum creatinine: 0.6 mg/dL in males and females
  • Age 2 to < 6 years: maximum serum creatinine: 0.8 mg/dL in males and females
  • Age 6 to < 10 years: maximum serum creatinine: 1 mg/dL in males and females
  • Age 10 to < 13 years: maximum serum creatinine: 1.2 mg/dL in males and females
  • Age 13 to < 16 years: maximum serum creatinine: 1.5 mg/dL in males and 1.4 mg/dL in females
  • Age >= 16 years: maximum serum creatinine: 1.7 mg/dL in males and 1.4 mg/dL in females
• Total bilirubin =< 1.5 x upper limit of normal (ULN) for age
• Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 110 U/L (for the purpose of this study, the ULN for SGPT is 45 U/L)
• Serum albumin >= 2 g/dL
• Shortening fraction of >= 27% by echocardiogram, or ejection fraction of >= 50% by gated radionuclide study
• Patients with seizure disorder may be enrolled if on anticonvulsants and well controlled
• All patients and/or their parents or legal guardians must sign a written informed consent
