Chemotherapy With CD133+ Select Autologous Hematopoietic Stem Cells for Children With Solid Tumors and Lymphomas

Secondary objectives for this protocol include the following:

• To describe CD133+ graft content post-selection and to describe the yield and purity of CD133+ content of the graft obtained.
• To describe the negative selection efficiency of this strategy by assessing the processed product for tumor specific markers, when applicable.
• To characterize the proliferation of clonal progeny of CD133+ cells.
• To characterize lymphocyte and hematopoietic reconstitution (including the kinetics of platelet engraftment) in these patients.
• To estimate one-year disease-free and overall survival in these transplant recipients.
