The purpose of this study is to show that myeloablative hematopoietic progenitor cell
transplantation (HPCT) continues to offer acceptable disease-free survival for select
patients requiring HPCT.
Myeloablative hematopoietic progenitor cell transplantation (HPCT) remains the standard of
care for patients requiring HPCT. The purpose of this study is to evaluate the morbidity and
mortality of myeloablative HPCT at Children's Memorial Hospital. It will also look to
determine the toxicity of a single conditioning regimen consisting of total body irradiation
(TBI), etoposide (VP-16), and Cyclophosphamide for patients with transplant eligible
lymphoid malignant conditions or with transplant eligible myeloid malignant conditions who
are receiving cord blood units, or to determine the toxicity of a single conditioning
regimen consisting of Busulfan and Cyclophosphamide for patients with transplant eligible
myeloid malignant conditions who are not receiving cord blood units.

- Relapsed lymphoma with residual disease that appears to be chemo-sensitive
and non-bulky (<5 cm at largest diameter)
- Venous Access: Three lumens of central vascular access will be required for all
patients entered on protocol due to the need for a dedicated line for continuous
