Autologous Stem Cell Transplants for Chronic Myelogenous Leukemia
1. To study ex-vivo purging of autologous hematopoietic stem cells that will be used to support high-dose chemotherapy in patients with chronic myelogenous leukemia (CML). Major endpoints are neutrophil engraftment and survival.
- To evaluate the toxicity of ex-vivo purged autologous cells when used to support high-dose chemotherapy.
- To evaluate the rate and duration of cytogenetic remissions achieved with this strategy.
- To determine the time to platelet recovery to 20,000/mm3.
- To determine the one-year survival rate.
