Graft-versus-host disease in stem cell transplantation.

Abstract

Graft-versus-host disease (GvHD) remains a major treatment-related risk in patients undergoing stem cell transplantation. Although advances in HLA-typing and graft types have reduced the risk of GvHD, a breakthrough in the treatment of severe GvHD is still lacking. Allogenic stem cell transplant has potentially beneficial immunological effects on the malignant disease necessitating transplantation, and the importance of these effects must be considered when treating GvHD.
