Summary

Studies have provided evidence that residual microscopic malignant cells in autologous bone marrow or blood stem cell grafts can contribute to posttransplant relapse. Researchers are currently exploring different methods in an attempt to purify or "purge" the stem cell product to minimize the risk of tumor contamination.

The CD133+ antigen is a protein contained on or "expressed" on numerous cells in the human body including specific hematopoietic progenitor (blood forming) cells. However, this antigen is not expressed on certain cancer cells including neuroblastoma. A technique using the investigational CliniMACS cell sorting device has been developed in an effort to filter out only those stem cells that express this CD133+ antigen in order to infuse a hematopoietic stem cell product with no tumor contamination potential.

The primary objective of this study is to establish safety of treating patients with a high dose chemotherapy regimen of Busulfan and Melphalan followed by autologous CD133+ hematopoietic stem cell support. Transplants recipients are expected to achieve engraftment as defined by an absolute neutrophil count of greater than or equal to 500/mm3 for three consecutive days by day 42-post infusion. Thus, safety of the treatment plan will be evaluated in terms of failure to engraft by this specific time period.

PROCEDURE

Stem Cell Transplantation

Autologous stem cell transplantation
