RATIONALE: Radioisotope therapy, such as iodine I 131 metaiodobenzylguanidine (MIBG), releases radiation that kills tumor cells. Drugs used in chemotherapy, such as topotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Topotecan may also make tumor cells more sensitive to iodine I 131 MIBG. A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by iodine I 131 MIBG and topotecan. This may allow more iodine I 131 MIBG and topotecan to be given so that more tumor cells are killed.
PURPOSE: This phase II trial is studying how well giving high-dose iodine I 131 MIBG together with topotecan and peripheral stem cell transplant works in treating young patients with relapsed stage 4 neuroblastoma or primary resistant high-risk neuroblastoma.
- Determine response (partial and complete response at metastatic sites) in children with relapsed stage 4 neuroblastoma or primary resistant high-risk neuroblastoma treated with high-dose iodine I 131 metaiodobenzylguanidine, topotecan hydrochloride, and peripheral blood stem cell transplantation.
- Determine the proportion of patients who, as a result of this treatment, are able to progress to potentially curative surgery and further systemic treatment.
- Correlate tumor dosimetry (to determine whether the tumor absorbed the radiation dose) with response in patients treated with this regimen.
- Determine the time to tumor progression.
OUTLINE: This is an open-label, multicenter study. Patients are stratified according to disease type (relapsed stage 4 vs primary resistant high-risk neuroblastoma).
Patients receive topotecan hydrochloride IV over 30 minutes on days 1-5 and 15-19 and high-dose iodine I 131 metaiodobenzylguanidine (^131I-MIBG) IV over 30 minutes on days 1 and 15. Patients receive autologous CD 34+ peripheral blood stem cells when ^131I-MIBG dosimetry levels reach an acceptable low on days 25-29.
Total whole-body absorbed dose is measured periodically after the first ^131I-MIBG dose is administered and periodically thereafter.
After completion of study treatment, patients are followed periodically for up to 10 years.
PROJECTED ACCRUAL: A total of 67 patients will be accrued for this study.

The aim of this study was to study the significance of combining iodine-123-cardiac metaiodobenzylguanidine scintigraphy (I-MIBG scintigraphy) and iodine-123-ioflupane (I-ioflupane) dopamine transport...
High-risk neuroblastoma is characterized by poor long-term survival, especially for very high-risk (VHR) patients (poor response of metastases after induction therapy). The benefits of a tandem high-d...
The mesenchymal stem cells (MSCs) of peripheral blood (PB) have been recognized as a promising source for allogeneic cell therapy. The objective of the present study was to isolate and characterize MS...

Graft failure affects approximately 5% of allogeneic stem cell transplants, with a poor prognosis. Salvage second allogeneic stem cell transplantation (alloSCT2) is limited by high rates of transplant...
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
Hematopoietic stem cells found in peripheral blood circulation.
The release of stem cells from the bone marrow into the peripheral blood circulation for the purpose of leukapheresis, prior to stem cell transplantation. Hematopoietic growth factors or chemotherapeutic agents often are used to stimulate the mobilization.
Stable iodine atoms that have the same atomic number as the element iodine, but differ in atomic weight. I-127 is the only naturally occurring stable iodine isotope.
Drug treatment designed to further diminish the disease toward complete remission following INDUCTION CHEMOTHERAPY. It helps to consolidate the gains during induction chemotherapy and may be followed by MAINTENANCE CHEMOTHERAPY.
