CD34+ selected cells in mismatched stem cell transplantation: a single centre experience of haploidentical peripheral blood stem cell transplantation.

Department of Internal Medicine III, Ulm University Hospital, Germany.


Over the past 3 years we have performed 10 haploidentical peripheral blood stem cell transplants in patients with incurable haematological malignancies and no prospect of a matched unrelated donor within an adequate time period. Conditioning consisted of ATG, TBI, thiotepa, cyclophosphamide and additional radioimmunotherapy in five patients. All patients received G-CSF mobilized peripheral blood stem cell grafts. GVHD prophylaxis consisted of T cell depletion by CD34+ selection; no post-transplant immunosuppression was given in nine patients. Stable engraftment was achieved in nine patients; one case of acute graft rejection was observed. Seven patients developed grade I acute GVHD, and six patients have developed chronic GVHD. Infections were the most significant clinical problem post transplant. Two patients have suffered a relapse of their disease and two further patients have died of transplant-related complications. After a median follow-up of 13 months (range 5-37 months) six patients are surviving in remission. We conclude that haploidentical PBSCT is a reasonable alternative to a MUD transplant.
