N2000-01: Double Infusion of Iodine I 131 Metaiodobenzylguanidine Followed by Autologous Stem Cell Transplantation

DISEASE CHARACTERISTICS:

• Diagnosis of neuroblastoma
• Confirmed by at least 1 of the following methods:
• Histology
• Clumps of tumor cells in bone marrow with elevated urinary catecholamine metabolites
• High-risk disease
• Poor response to induction therapy OR relapse defined by any of the following:
• No response, stable disease, or mixed response after a minimum of 3 prior courses of chemotherapy
• More than 100 tumor cells per 10^5 nucleated cells on bone marrow immunocytology after at least 3 prior courses of chemotherapy
• Progressive disease at any time during or after therapy
• Patients with massive bone marrow invasion (more than 50% replacement of bone marrow by tumor cells) are allowed
• Must have positive iodine I 131 metaiodobenzylguanidine (^131I-MIBG) within the past 6 weeks or subsequent to any other prior antitumor therapy delivered within the past 6 weeks
• Must meet the following criteria for minimum number of autologous stem cells:
• Unpurged peripheral blood stem cells (PBSC)
• Minimum of 1,500,000/mm^3 CD34-positive cells/kg
• Collected products must have < 1 tumor cell/100,000 normal cells by immunocytology
• PBSC purged with immunomagnetic beads
• Minimum of 1,000,000/mm^3 viable CD34-positive cells/kg
• Collected products must have < 1 tumor cell/100,000 normal cells by immunocytology
• CD34-positive selected PBSC products are not allowed
• Patients who had PBSC collected previously with no immunocytological testing available may use those products provided bone marrow is tumor free by bilateral bone marrow aspirate AND biopsy for morphology is performed within 4 weeks before PBSC collection
• Patients with no tumor involvement in bone marrow at diagnosis and PBSC collection before any disease progression do not require documentation of negative bone marrow morphology
