N2001-03: CEP-701 in Treating Young Patients With Recurrent or Refractory High-Risk Neuroblastoma

DISEASE CHARACTERISTICS:

• Diagnosis of neuroblastoma confirmed by at least 1 of the following:
• Histology
• Demonstrates clumps of tumor cells in the bone marrow with elevated urinary catecholamine metabolites
• Recurrent or resistant/refractory disease
• Neuroblastoma metastatic to the bone marrow with granulocytopenia, anemia, and/or thrombocytopenia allowed
• High-risk disease
• Patients in first response after completion of a prior front-line myeloablative regimen OR who were medically ineligible to receive a front-line myeloablative regimen must meet at least 1 of the following criteria:
• Viable neuroblastoma determined by biopsy of a persistent lesion as seen on CT scan, MRI, or metaiodobenzylguanidine (MIBG) scan
• If lesion was irradiated, biopsy must be performed at least 4 weeks after completion of prior radiotherapy
• Morphologic evidence of tumor in bone marrow
• Second or greater response (without histologic confirmation) allowed
• Meets at least 1 of the following criteria:
• At least 1 unidimensionally measurable lesion on CT scan, MRI, or X-ray
• At least 20 mm by conventional techniques OR at least 10 mm by spiral CT scan
• MIBG scan with positive uptake at a minimum of 1 site
• Bone marrow with tumor cells on routine morphology (not by NSE staining only) of bilateral aspirate and/or biopsy AND/OR at least 5 tumor cells/10^6 mononuclear cells in the bone marrow by immunocytologic analysis of 2 consecutive bone marrows performed at least 1 day but no more than 4 weeks apart
