A central venous catheter (plastic tube) will be placed into the large chest vein. The catheter will be left in place throughout treatment. In order to collect stem cells, G-CSF and GM-CSF will be injected under the skin. This will be done twice a day until the collection of stem cells is complete. You will receive Campath -1H through the catheter on Days 1, 2, 3, and 10 of chemotherapy treatment.
