To date, no curative option exists for patients with relapsed or refractory stage IV neuroblastoma after previous autologous stem cell transplantation. Our preliminary results of RIC allo-HSCT (protocol RICE) indicate the feasability and low toxicity of allograft in heavily pre-treated children. Furthermore RIC SCT and immunomagnetic CD3/CD19 graft depletion may allow HHCT with lower toxicity and faster engraftment. CD3/CD19 depleted grafts not only contain CD34+ stem cells but also graft-facilitating cells, CD34- progenitors, dendritic and natural killer cells which may allow stable engraftment and participate to GvT effect.
After haploidentical stem cell transplantation anti tumour activity exerted by donor derived NK cells could be stimulated by NK cells injections. Those effects may help to reduce the relapse rate and to impove the outcome of those patients. The investigators prospectively evaluated engraftment and immune reconstitution.
This RICE NK protocol is a multicenter study of Haplo- HSCT using RIC with fludarabine (180 mg/m2), Busulfan IV (3,2 to 4,8 mg/kg/d), TBI 2 grays and CD3/CD19 graft depletion. A minimum of 8 106 CD34+ cells/kg were infused on day 0. No post grafting immunosuppression was applied if the graft contained < 2.5 x 104 CD3+ cells/kg. At Day 30 and 60 post-graft we perform an donor CD56+ cells injection. The investigators develop this strategy in an European collaboration working on haploidentical stem cell transplantation for childhood refractory and metastatic solid tumors.

Objectives: 1. To determine the relative toxicities, engraftment potential, kinetics of engraftment, degree of chimerism and disease control achieved with the combination of fludar...
The goal of this clinical research study is to learn if cyclophosphamide given after busulfan and fludarabine can help to prevent graft versus host disease (GVHD - a condition in which tra...
The purpose of this study is to evaluate the OS, RFS, and TRM after HCT with low-dose total body irradiation, fludarabine, and busulfan conditioning.
RATIONALE: Giving low doses of chemotherapy, such as fludarabine and busulfan, and antithymocyte globulin before a donor stem cell transplant helps stop the growth of tumor cells. It may a...
Double umbilical cord blood transplantation (DUCBT) following high dose or reduced intensity conditioning will be well-tolerated and result in a high degree of engraftment in patients with...
Fludarabine with busulfan (FB) or melphalan (FM) are two more commonly used reduced intensity conditioning regimens for allogeneic stem cell transplantation (HCT).We present a systematic review and me...
Addition of melphalan to fludarabine/busulfan (FLU/BU4/MEL) provides survival benefit for patients with myeloid malignancy following allogeneic bone-marrow transplantation/peripheral blood stem-cell transplantation.
A conditioning regimen with fludarabine and myeloablative dose of busulfan (FLU/BU4) has been commonly used in allogeneic hematopoietic cell transplantation (allo-HCT). However, there are two major pr...
Neuroblastoma (NB) is the most common extracranial solid tumor of childhood. Primary and secondary testicular involvement is extremely uncommon in neuroblastoma.
Neuroblastoma is a lethal tumor that commonly occurs in children. Polymorphisms in reportedly influence risk for several types of cancer, though their roles in neuroblastoma remain unclear. Here we e...
In this study we utilized a large animal model to identify a dose of intravenous busulfan that can cause reversible myelosuppression. Nine baboons (Papio anubis) were treated with IV busulfan at 6.4 (...
An alkylating agent having a selective immunosuppressive effect on BONE MARROW. It has been used in the palliative treatment of chronic myeloid leukemia (MYELOID LEUKEMIA, CHRONIC), but although symptomatic relief is provided, no permanent remission is brought about. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), busulfan is listed as a known carcinogen.
An indolocarbazole that is a potent PROTEIN KINASE C inhibitor which enhances cAMP-mediated responses in human neuroblastoma cells. (Biochem Biophys Res Commun 1995;214(3):1114-20)
A malignant olfactory neuroblastoma arising from the olfactory epithelium of the superior nasal cavity and cribriform plate. It is uncommon (3% of nasal tumors) and rarely is associated with the production of excess hormones (e.g., SIADH, Cushing Syndrome). It has a high propensity for multiple local recurrences and bony metastases. (From Holland et al., Cancer Medicine, 3rd ed, p1245; J Laryngol Otol 1998 Jul;112(7):628-33)
A moderately malignant neoplasm composed of primitive neuroectodermal cells dispersed in myxomatous or fibrous stroma intermixed with mature ganglion cells. It may undergo transformation into a neuroblastoma. It arises from the sympathetic trunk or less frequently from the adrenal medulla, cerebral cortex, and other locations. Cervical ganglioneuroblastomas may be associated with HORNER SYNDROME and the tumor may occasionally secrete vasoactive intestinal peptide, resulting in chronic diarrhea.
Genes of IAP elements (a family of retrovirus-like genetic elements) which code for virus-like particles (IAPs) found regularly in rodent early embryos. ("Intracisternal" refers to the cisternae of the endoplasmic reticulum.) Under certain circumstances, such as DNA hypomethylation they are transcribed. Their transcripts are found in a variety of neoplasms, including plasmacytomas, neuroblastoma, rhabdomyosarcomas, teratocarcinomas, and colon carcinomas.
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
