ELIGIBILITY CRITERIA

Inclusion Criteria:

• Patients must be enrolled on ANBL00B1 or APEC14B1 prior to enrollment on ANBL1531
• Patients must have a diagnosis of neuroblastoma or ganglioneuroblastoma (nodular) verified by tumor pathology analysis or demonstration of clumps of tumor cells in bone marrow with elevated urinary catecholamine metabolites; the following disease groups are eligible:
  
  • Patients with International Neuroblastoma Risk Group (INRG) stage M disease are eligible if found to have either of the following features:
    
    • MYCN amplification (> 4-fold increase in MYCN signals as compared to reference signals), regardless of age or additional biologic features; OR
    • Age > 547 days regardless of biologic features
  • Patients with INRG stage MS disease with MYCN amplification
  • Patients with INRG stage L2 disease with MYCN amplification
  • Patients > 547 days of age initially diagnosed with INRG stage L1, L2 or MS disease who progressed to Stage M without prior chemotherapy may enroll within 4 weeks of progression to Stage M
  • Patients >= 365 days of age initially diagnosed with MYCN amplified INRG stage L1 disease who progress to Stage M without systemic therapy may enroll within 4 weeks of progression to stage M
• Patients initially recognized to have high-risk disease must have had no prior systemic therapy (other than topotecan/cyclophosphamide initiated on an emergent basis and within allowed timing); patients observed or treated with a single cycle of chemotherapy per a low or intermediate risk neuroblastoma regimen (e.g., as per ANBL0531, ANBL1232 or similar) for what initially appeared to be non-high risk disease but subsequently found to meet the criteria will also be eligible; patients who receive localized emergency radiation to sites of life-threatening or function-threatening disease prior to or immediately after establishment of the definitive diagnosis will be eligible
• Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 or a serum creatinine based on age/sex as follows:
  
  • 1 to < 2 years: male = 0.6; female = 0.6
  • 2 to < 6 years: male = 0.8; female = 0.8
  • 6 to < 10 years: male = 1; female = 1
  • 10 to < 13 years: male = 1.2; female = 1.2
  • 13 to < 16 years: male = 1.5; female = 1.4
  • >= 16 years: male = 1.7; female = 1.4
• Total bilirubin =< 1.5 x upper limit of normal (ULN) for age, and
• Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) < 10 x ULN; for the purposes of this study, ULN for SGPT (ALT) is 45
• Shortening fraction of >= 27% by echocardiogram, or ejection fraction of > 50% by echocardiogram or radionuclide angiogram
• No known contraindication to peripheral blood stem cell (PBSC) collection; examples of contraindications might be a weight or size less than the collecting institution finds feasible, or a physical condition that would limit the ability of the child to undergo apheresis catheter placement (if necessary) and/or the apheresis procedure.

Exclusion Criteria:

• Patients with INRG stage L2 tumors without amplification of MYCN regardless of tumor histology (may meet criteria for may meet criteria for high risk classification but are not eligible for this trial)
• Patients with bone marrow failure syndromes
• Patients for whom targeted radiopharmaceutical therapy would be contraindicated due to underlying medical disorders
• Female patients who are pregnant; a pregnancy test is required for female patients of childbearing potential
• Lactating females who plan to breastfeed their infants
• Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of their study participation.
