Beschreibungen/Notizen

• Allogeneic hematopoietic stem cell transplantation (allo-SCT) is a potentially curative treatment option for eligible patients with chronic lymphocytic leukemia (CLL). However, it is known that cure of CLL is only possible if a graft-versus-leukemia effect is present. Between 1994 and 2007, 48 adults underwent allo-SCT for poor-risk CLL in Sweden. Of these, ten (21 %) patients aged 24–53 years (median: 46 years) received myeloablative conditioning (MAC), based on TBI and cyclophosphamide. All MAC patients had refractory, poorly controlled CLL before allo-SCT (partial remission in 9/10 patients and progressive disease in one). The cumulative incidence of acute graft-versus-host disease (GVHD) grades II–IV was 30 %. Nine patients developed chronic GVHD; extensive in four. Rates of nonrelapse mortality at 1, 3 and 10 years were 0, 10 and 20 %, respectively. Two patients relapsed 36 and 53 months after transplantation. Six patients were still alive after a median follow-up time of 11.5 years (range 5.9–13.7). The probabilities of relapse-free and overall survival from 1, 3 and 5 years after transplantation were 100, 90 and 70 %, and 100, 90 and 80 %, respectively. Nevertheless, our analysis of long-term outcome after MAC allo-SCT for CLL suggests that younger patients with poorly controlled CLL may benefit from MAC allo-SCT.
