 The purpose of this study is: 1 to try to kill any cancer or precancer cells that are in your body, and to reduce the side effects of a transplant, which we have seen in our previous studies, 2 to see if this treatment with a new recipe of radiation and chemotherapy can suppress your immune system enough for the stem cells to take and grow, 3 to see if the specially prepared stem cells can grow in you without a problem called graft-versus-host disease GvHD occurring.
