OBJECTIVES: Primary * Determine the maximum tolerated red marrow radiation dose delivered and associated toxic effects of escalating activity of iodine I 131 metaiodobenzylguanidine (\^131I-MIBG) followed by autologous hematopoietic stem cell transplantation in patients with refractory neuroblastoma. * Determine the number of days after stem cell transplantation to achieve absolute neutrophil count ≥ 500/mm\^3 for 3 days and platelet count ≥ 20,000/mm\^3 for 3 days (without transfusions) in patients treated with this regimen. Secondary * Determine the response rate in patients treated with this regimen, based on lesions measurable by CT or MRI at study entry, patients with \^131I-MIBG scan-positive lesions only, and patients with minimal residual tumor in bone marrow who have complete response by immunocytology and morphology. * Determine the tumor absorbed radiation dose in patients with measurable soft tissue lesions treated with this regimen. * Correlate, if possible, TP53 mutations with response in patients with accessible bone marrow tumor treated with \^131I-MIBG. OUTLINE: This is a dose-escalation, multicenter study. * Iodine I 131 metaiodobenzylguanidine (131I-MIBG) therapy: Patients receive\^131I-MIBG IV over 2 hours on days 0 and 14. Cohorts of 3-6 patients receive escalating doses of \^131I-MIBG until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. * Stem cell transplantation therapy: Patients undergo autologous peripheral blood stem cell transplantation on day 28. Patients receive filgrastim (G-CSF) IV over 1 hour OR subcutaneously daily beginning on day 28 and continuing until blood counts recover. Patients are followed every 3 months for 1 year and then annually thereafter. PROJECTED ACCRUAL: A total of 9-18 patients will be accrued for this study within 2 years.

Protocole

Cette section fournit des détails sur le plan de l'étude, y compris la manière dont l'étude est conçue et ce qu'elle évalue.
Détails du design

18 participants à inclure

Nombre total de participants que l'essai clinique vise à recruter.

Traitement

Cette étude teste un ou plusieurs traitements pour évaluer leur efficacité contre une maladie ou un problème de santé spécifique. L'objectif est de voir si un nouveau médicament ou une thérapie fonctionne mieux, ou provoque moins d'effets secondaires que les options existantes.

Éligibilité

Les chercheurs recherchent des patients correspondant à une certaine description appelée critères d'éligibilité : état de santé général ou traitements antérieurs du patient.
