 Blood stem cells will be collected when your blood counts have returned to normal about 10-16 days after chemotherapy. The process of stem cell collection takes about 4 hours each time. You will have stem cells collected each day until enough are collected between 1-6 sessions. A machine is attached to the CVL and blood is withdrawn. The blood then flows through the machine, which removes stem cells from the blood. The blood is then returned back to you through the CVL. The stem cells are then frozen and stored. These stem cells will be given back to you after the next phase of treatment to help your blood counts recover after high dose chemotherapy. After enough stem cells have been collected, you will be admitted to the hospital for high dose chemotherapy. You will sign a separate consent before you receive high dose chemotherapy.
