Bone Marrow Transplants to Cure Lymphomas/Thymomas
  • Whole Body Irradiation to remove endogenous
    immune system and tumor
  • Also total lymphoid irradiation with
    antithymocyte serum
  • Injection of bone marrow from a well matched
    donor to re-establish immune system
  • Regulation of immune response to prevent graft
    versus host reaction.
  • Autologous donation possible if one can purify
    and remove tumor cells, enriching for stem
    cells..
  • Allogeneic donors have advantage of graft versus
    tumor reaction to kill any remaining tumor cells.
  • Allogeneic donors have the disadvantage of graft
    versus host reaction if they are not well
    matched.

Complications of Allogeneic Transplants
  • Transplant related mortality 10 - 15
  • Regimen related toxicity
  • Infectious complications
  • Engraftment failure (resistance)
  • Graft-versus-host disease

Other Applications ofHematopoietic Stem Cell
Transplantation
  • Treatment of autoimmune disease
  • Patients treated with bone marrow transplants are
    often cured of autoimmune disease
  • Bone marrow transplant donors with autoimmune
    disease can pass the disease on to recipients
  • Organ tolerance induction
  • Mice receiving organ transplant and HSC
    transplant together are tolerant and no rejection
    occurs. No immune suppressants are needed.
