Bone Marrow and Stem Cell Transplants to Treat Lymphoma |

Transplants (BMTs) and their cousin the Peripheral Blood Stem Cell Transplant (PBSCT) are
moving from the clinical trial area to mainstream treatment for many cancers, including Hodgkin's Disease and Medium/High grade (aggressive)
Non-Hodgkin's lymphoma. Transplants are used
often for patients who relapse from standard chemotherapy. Bone marrow transplantation (BMT) has been used to treat lymphoma for over ten years, much of that time on a trial basis but |
|||
| now much more in the mainstream. Sometimes lymphoma becomes resistant to treatment with radiation therapy or chemotherapy. Very high doses of chemotherapy may then be used to treat the cancer. Because the high doses of chemotherapy can destroy the patient's bone marrow, | |||
| marrow is taken from the bones before treatment. The marrow is then frozen, and the patient is given high-dose chemotherapy with or without radiation therapy to treat the cancer. The marrow that was taken out is then thawed and given back through a needle in a vein to replace the marrow that was destroyed. This type of transplant is called an autologous transplant. If the marrow given is taken from another person, the transplant is called an allogeneic transplant. Another type of autologous transplant is called a peripheral blood stem cell transplant (PBSCT). The patient's blood is passed through a machine that removes the stem cells (immature cells from which all blood cells develop), then returns the blood to the body. This procedure is called apheresis and usually takes 3 or 4 hours over one or more days to complete. The stem cells may be treated with drugs to kill any cancer cells and then frozen until they are transplanted back to the patient. This procedure may be done alone or with an autologous bone marrow transplant. Studies have shown that PBSCT results in shorter hospital stays, is safer, and more cost effective than BMTs. Some centers have looked into transplants after first remission as a preventative
measure. Lymphoma BMT & PBSCT InformationBone

|||
| Apheresis (pheresis/leukapheresis) is the collection of stem cells for a transplant. Thanks to the people at COBE® BCTTM, we now have a good introduction to stem cell collection. |

Granulocyte Colony-Stimulating Factor (G-CSF) is a
treatment agent used to stimulate the production of granulocytes in the bone marrow.
Manufactured by Amgen under the name
Neupogen® , it is often given
during or after chemotherapy to boost the immune system. It is also used before stem cell
collection to boost the granulocytes prior to collection.Donor Programs
